This is an extended version of an article which appeared at https://www.gerryanderson.co.uk/ on 28th January 2021 –
60th Anniversary of the first broadcast of Supercar on TV.
Supercar – The Wonder of the Age for Six Decades!
First Broadcast: 28th January 1961
Gerry Anderson TV was a backdrop to my school years in the early 1960s, a favourite when returning home from school. Having seen the programmes from Twizzle, Torchy and Four Feather Falls.. Kaiya Kalamakooya kala kaiya! … and beyond. But my absolute favourite was always Mike Mercury in Supercar!
Supercar is an experimental multi-purpose vertical take-off and landing craft. As well as its ability to fly, Supercar can travel on and under water, on land with a ground effect cushion from its vertical boosters, and even go into space. It is designed to perform a range of missions including search and rescue. Supercar is based at the Supercar team base in the remotely located Black Rock Laboratory within Black Rock Desert in Nevada, USA.
Well… there she is Mike….Supercar! [YouTube Episode 1 (3:25)]
… exclaimed by Professor Popkiss to Mike Mercury as Supercar is finishing a ground test in the first episode still sends tingles through my spine. The tech details were really appealing to my interests in science, engineering and aerospace. All the procedures for the familiar Gerry Anderson “launch sequence” began in Supercar…
Charging port engine, …, 9000, 12000, 15000, interlock on, Fire One
There are lots of superb details. I like the one where Dr. Beaker is examining a Supercar engines test and commenting on the crazing of the ceramic material of the blast shield. Reg Hill did a fine job of designing Supercar and giving it exciting capabilities on land, under the sea, in the air and even into space.
The sound effects for Supercar startup and flight added much to the atmosphere and Barry Gray’s music added a lot to all the Gerry Anderson TV series.. and Supercar has a very rich repertoire of themes and incidental music. The “Mike Mercury March” (aka “Mike’s Theme”) played as Supercar races to the scene of another rescue is wonderful.
While still at school I was so keen that I arranged a petition and got thousands of signatures from locals to send to ITV and AP Films to ask them to produce more episodes and show Supercar more on TV.
Having seen adverts in TV Comic, I was an early member of the Supercar Club which had a tie up with National Benzole “Super National” petrol and produced a flexi-disc with a Supercar story along with the Supercar theme and more Barry Gray music. I still smile when I remember my dad pulling into a National station to fill up, and as we drove away he accelerated fast and shouted out “zooooom”. The annuals each year, several Shipton Plastics “Plaston” PVC models (which we floated in our fish pond and tried to film in action in front of a back projection sheet), Budgie diecast Supercars and more merchandise followed. My dad, who had been in the Navy, even got me a captain style hat like Mike Mercury wore which I mounted my Supercar wings on.
It is wonderful that over the years since then we have been able to get the whole 39 episodes of Supercar from Series One and Series Two on DVD and that many new merchandising items and fan produced materials have appeared to keep the contents alive.
When Supercar was still on air in the early 1960s, I was taken by my dad to a TV trade show at Earls Court on London, as he ran a TV retail and repair store. And as we went around I heard a loud announcement that “Anything can happen in the next half hour”! Turning round to the big screen just in time to see the black and white image turn to COLOUR and STINGRAY appear. So there was plenty to look forward to, even though Supercar remained my interest.
A number of scientists and engineers have noted how they were influenced in their career choices and areas of interest from watching early Gerry Anderson programmes. And so it was in my case too. The Black Rock Laboratory team under Professor Popkiss and Doctor Beaker created Supercar (fictionally) using a grant from the US Air Force and their research people. Reality can follow fiction… I have (in real life) received research funding for my Artificial Intelligence work on planning, command and control of spacecraft and in search and rescue applications from the US Air Force Research Laboratory and the US Defense Advanced Research Agency (DARPA) using the very same research mechanism that funded the X-15 rocket plane (and, one imagines, Supercar).
I have been fortunate to be part of the international community who continue to enjoy Gerry Anderson TV and work with some very creative people all round the world who are also very interested in Supercar over the years.
60 years later and Supercar is still in my life via the detailed and accurate 3D models produced 25 years ago with friends and collaborators around the globe and still looking good today as computer graphics have improved. The fan produced resources and computer models created with others internationally has enabled me to create virtual world and virtual reality experiences to continue to enjoy Supercar, to visit the (virtual) Black Rock Laboratory and take Supercar out for a spin in flight simulators and space simulators.
Mick Imrie in the UK in the late 1990s created Supercar and Black Rock Laboratory 3D computer models, originally in Cinema4D and subsequently ported by others in the Gerry Anderson Model Makers Alliance (GA-MMA) to Studio 3D Max, Lightwave, etc. See Supercar 3D Model – Mick Imrie and Austin Tate – 1998
Shane Pickering, a private pilot in New Zealand, in the late 1990s worked on schematics and internal details for Supercar compatible with the TV shows and annuals. See Supercar Schematics – Shane Pickering and Austin Tate – 1999.
Brian Douglas, a Microsoft Flight Simulator enthusiast in the UK, worked with me in 2003 to improve the visual appearance and flight dynamics for the earlier versions of Supercar for Flight Simulator I had created. See Supercar for Flight Simulator – 1996-2003.
Kez Wilson at Misc!Mayhem in Texas created the Supercar Comic published in 2003, working with script writer Michael Wolff, and I was happy to help with its production using our 3D models used to get accurate outlines for rotascoping of some image panels. I met up with Kez and Graydon Gould, the voice of Mike Mercury, at a Fanderson event that same year. See Supercar Comic – Kez Wilson and Michael Wolff – 2001-2003.
Playing Mantis in the USA produced the Johnny Lighting miniature diecast Supercar models originally in 2001 with colouring reflecting “The Little Golden Book” drawn images. Working with their designer Alan Pletcher I was able to give a little input to improve the later versions for colour and details to better reflect Supercar as seen on TV. I was fortunate to get deliveries of each new variant and limited edition that came out over the following years.
I have also had fun interactions with Martin Woodhouse (who along with his brother Hugh wrote the stories for Supercar series one), Dirk Maggs and some of the good folks at Fanderson.
The fan produced resources and computer models created with others internationally has enabled me to create virtual world and virtual reality experiences to continue to enjoy Supercar, to visit the (virtual) Black Rock Laboratory and take Supercar out for a spin in flight simulators and space simulators.

Firestorm VR Mod is a version of the popular Firestorm Viewer for Second Life and OpenSimulator with modifications to provide VR capabilities for VR Head Mounted Displays (HMDs) via SteamVR. Firestorm VR Mod 22.214.171.124831 is now available from https://github.com/humbletim/firestorm-gha/releases (Assets)
|Table of Contents|
|Usage||Black Edges||Black Display||Settings||FPS Advice|
|Fn Keys||Xbox||3D SpaceNav||Source||VRLand Test|
Firestorm 126.96.36.199831 includes support for EEP (the Environmental Enhancement Project), support for the Chrome Embedded Framework Live Video Streaming, and various improvements for OpenSim support.
Peter Kappler maintains “P373R VR Mod” source code modifications to allow the Firestorm Viewer to work with VR headsets at https://gsgrid.de/firestorm-vr-mod/ – go there to download his latest viewer add on modification source code and for his usage information, advice on trouble shooting, etc.
@humbletim has created an automated scripted build system initiated by @thoys using GitHub Actions (GHA) which merges Peter Kappler’s VR Mod code additions into stock Firestorm and which can autobuild a release executable version. See https://github.com/humbletim/firestorm-gha/. Look under the Releases tab for the Firestorm VR Mod 188.8.131.52831 entry and then the installer for Firestorm VR Mod 184.108.40.206831 for various platforms is under the “Assets” chevron.
VR Mode instructions are available via prompts in the viewer or via information on https://gsgrid.de/firestorm-vr-mod/. In short…
Firestorm VR Mod shifts the display in VR mode to an edge if the mouse or pointer is placed towards an edge or corner of the viewer window. This is to allow easier access to menus, user interface buttons and HUDs. It can be confusing though if you enter VR mode and find that part of the view is black. It is usually because the mouse is placed towards a corner or edge. Just move the mouse back to the centre of the screen and the full VR view should appear.
This was an issue in earlier versions and is mostly resolved now… but it can still occur with some headsets. In case you encounter issues with a black HMD display… Peter Kappler suggests the following:
Firestorm VR Mod installs into its own folder and uses its own user Settings directory so that the VR Mod viewer can be installed alongside the standard Firestorm viewer. Note that if you want to import existing Firestorm accounts/settings you have to manually copy them over between AppData/Roaming/Firestorm_x64 and AppData/Roaming/FirestormVR_x64 folders.
As usual, Ctrl+TAB initially sets up SteamVR (and HMD support as needed), TAB is used to toggle VR mode on or off, F5 lets you select and step through the various VR HMD or user specific settings for IPD, texture shift to register the left and right eye images, and focal distance to change depth perception, etc. F6/F7 are used to increment and decrement each setting selection.
Peter Kappler suggested the following process to establish suitable settings for your HMD:
If you see a lot of hover tips showing under the mouse it could be that the debug setting “ShowHoverTips” is set to TRUE (the default) which may show something constantly under the mouse even for inert unscripted objects. You can turn that off via Debug Settings or via Preferences > User Interface > 3D World > Show Hover Tips. Via that same preferences panel, you might alternatively prefer to lengthen the delay before hover tips are activated.
In VR Mode it may be useful to show local nearby chat in “bubbles” over each avatar’s head. This can be done via Preferences > Chat.
You do need to ensure you have a good frame rate to have a comfortable VR experience. The Firestorm VR Mod Viewer will not work well if the Second Life/OpenSim region you visit cannot normally be displayed in 2D with a decent frame rate. In VR mode you can assume you will get roughly 50% of the frame rate that shows on the 2D normal screen. At low frame rates bad flickering will occur in VR mode. My suggestion is to look at the frame rate (in Firestorm it is displayed in the upper right hand corner of the viewer) and to adjust the graphics settings (especially draw distance, shadows and quality sliders) until you have around 100fps (and definitely more than 50fps) and then try VR.
Peter Kappler also suggested: Particles… a fireplace is going to eat 20 to 30 fps! So turn them off for VR.
In some situations the rendering of Linden Water, the water surface and its effects, can significantly reduce frame rates. In an environment that makes sense, such as a meeting room, disabling Linden Water can boost frame rates. Do that via Advanced (Ctrl+Alt+D) > Rendering Tyles > Water (or keyboard shortcut Ctrl+Shift+Alt+7).
Tips from David Rowe for using the CtrlAltStudio VR Viewer (which is no longer maintained) may also be relevant:
If you have issues with some of the Function keys (F5 or other Firestorm VR Mod keys) not working… look to see if the F keys involved are mapped to active “Gestures”. You can find a list of the gestures you currently have active and the keys associated with them using the “Gestures” toolbar button… or the Comm -> Gestures menu item (Ctrl+G shortcut).
An Xbox One controller as used with the Oculus Rift (or an Xbox 360 controller) can be enabled, as usual, in Firestorm via Preferences -> Move & View -> Movement -> Joystick Configuration -> Enable Joystick.
You will probably find the controls are under or over sensitive, or some buttons and triggers don’t do what you expect. See this blog post and the image here (click for a larger version) for some suggestions as to how to amend the settings…
You might want to enter “-1” rather than axis “5” as an indication that axis is not mapped. With the setup suggested the “A” button toggles between the normal avatar view and “FlyCam” mode allowing you to move the camera separately to the avatar.
As with all versions of Firestorm, the viewer supports other forms of “joystick”. One is the 3Dconnexion SpaceNavigator (aka SpaceMouse) which is a “3D mouse” supporting both avatar motion and by clicking the left hand button the separate “FlyCam” camera control.
My recommendation is to install the SpaceNavigator just by plugging it into Windows and receiving default Windows drivers for the device. I do not install any special SpaceNavigator drivers as suggested on the Second Life Wiki, some of which are incompatible with Second Life viewers.
This version of Firestorm VR Mod 220.127.116.11831 is based on the Firestorm source code at Commit r63477:5b44308aee43 (Wed, 02 Dec 2020 21:32:05). Firestorm source is available at https://vcs.firestormviewer.org/phoenix-firestorm. Look under “Commits” and select the branch for Firestorm_6.4.12 (link here).
With Firestorm VR Mod Peter Kappler uses a coding approach which injects VR capabilities into the Firestorm Viewer to make the mod easier to maintain in future and for others to repeat or adapt. The source is available from his web page at https://gsgrid.de/firestorm-vr-mod/ [Local Copy].
Impressively, the source is written in a way that it requires only some editing in the llviewerdisplay.cpp and adding 2 files to the project. All changes are marked with #####P373R##### comments. Peter also included the openvr header and lib files you will need in the rar. For information about the rest of the files you will need, read how to compile Firestorm at https://wiki.firestormviewer.org/fs_compiling_firestorm.
Note that the VR Mod source remains stable since version 6.3.3 with no changes are needed for insertion into Firestorm 6.4.12.
The GitHub Actions (GHA) source by @HumbleTim used to combine Firestorm source and Peter Kappler’s P373R VR Mod addons and build it using Visual Studio 2019 is available via https://github.com/humbletim/firestorm-gha (Firestorm_6.4.12_VR Branch)

[OpenSim code development from 2008 to 2017… Youtube]
Firestorm 18.104.22.168792 (15-Nov-2020) is now at Release Candidate stage and undergoing final QA testing. There are improvements to the handling of OpenSimulator “hop” addresses, especially to ensure that the current grid is inserted into Hypergrid addresses rather than always (incorrectly) using the original login grid.
This is an issue that has been outstanding for some time in virtual world viewers that support access to OpenSim. See, for example, Firestorm JIRA FIRE-10549. My own test page for hops has been tracking progress on this for over 7 years and is at http://www.aiai.ed.ac.uk/~ai/hg.html
To show you how far this has moved things forward in the latest Firestorm viewer… here are tests starting with a local login avatar (e.g. on AiLand) and a login avatar on OSGrid (a well used open grid) and then using the following hop addresses in the address bar. It includes hops to OpenSim software based on various versions including 0.8.2.1 (now over 5 years old code), 0.9.1.0, 0.9.1.1 and 0.9.2.0 dev (the latest in development version) grids, and even some grids with “Modified” code. Of course I deliberately avoided grids I know will fail (see later)… but note one of the hops is for OSGrid which separates the hg.osgrid.org GatekeeperURI and login.osgrid.org LoginURI and does assume the default :80 without including it in the address. PROGRESS
Start via your own local avatar login on a grid on any recent, properly configures Grid and region. E.g., for me that is an Ailand avatar login on AiLand…
Start via local OSGrid avatar login at, e.g., Vue-Port region…
Also note that due to a separate OpenSim/OSGrid issue, repeat returns to some 0.9.2.0 grids need TWO teleport tries to work. First reports “You appear to be already logged in. Try again”. Second always works. See http://opensimulator.org/mantis/view.php?id=8802
Problematic or Failing Grids/Regions
Grids that separate their LoginURI (e.g. login.zetaworlds.com:80) and GatekeeperURI (e.g. hg.zetaworld.com:80) are still problematic – and it may be that the Simulator Features OpenSim Extras GridURL is incorrectly set via the grid’s configuration. GridURL is set from the Robust GatekeeperURI overridden by the region’s config-include/GridCommon.ini GatekeeperURI.
OSGrid appears to work in hops and it is another example of a grid that separates its LoginURI (e.g. login.osgrid.org:80) and GateKeeperURI (e.g. hg.osgrid.com:80) but in its region config-include/GridCommon.ini it adds aliases to the GateKeeperURI to its LoginURI. This may indicate that the viewer is not yet properly picking up the GridURL/GatkeeperURI and using it for all Hypergrid teleports.
Some DreamGrid-based grids seem to have some issue and also fail… e.g., I cannot hop to one of my own experimental grids (not running all the time):
Some regions on OSGrid (e.g. Lani) will ALWAYS give “The region you tried to teleport to doesn’t exist anymore” message, which I am exploring with the region owner. OSGrid Lani region is not reporting its GridURL in SimulatorFeatures SimulatorExtrtas. It appears to be on OpenSim code from 2015.
Fails with “The region you tried to teleport to doesn’t exist anymore”
Edit the logcontrol.xml file in the Firestorm install folder… on Windows for the 64bit Firestorm release that is for example C:\Program Files\FirestormOS-Releasex64\app_settings. Go to the bottom and see a line with “import” in it. COPY that line TWICE leaving those there now in place and change the extra lines to GridManager (no space) and SLURL.
You can then explore the way in which the viewer creates each hop or “SLURL” by searching for “#SLURL#” lines in the Firstorm.log files created for each run of the viewer which is put in a location such as C:\Users\yourname\AppData\Roaming\Firestorm_x64\logs.
You can also explore what information a Grid/Region is giving back to the viewer when teleports occur. This is communicated on a call by the viewer of “setSimulatorFeatures” (look for that string in the Firestorm.log file) and returned in XML format by the destination “root” or “main” region and each “child” region within the viewer draw distance range. This contains OpenSimulator specific parameters in an “OpenSimulatorExtras” section.
Hypergrid destination regions are temporarily mapped to the source grid local map at any value of X and Y < 32. This range is reserved so large regions can fit. Region corner is parked at y = 0.
avatar_skeletonV3.blend replaces avatar_skeleton_with_custombonesettings.blend, and has two armatures in the .blend file… use the avatar_skeleton.xml armature for rigging to export as Collada for Second Life and OpenSim.
These notes are a reminder of the process to use Blender to take the Ruth2 v4 mesh avatar, add an “armature” for rigging and go through the process of exporting Collada (.dae) and importing to Second Life/OpenSim. It follows a very helpful tutorial on 4th November 2020 by Ada Radius and Kayaker Magic on Discovery Grid.
Simple Process Guide
Open Blender with a new project, remove default cube.
Check if Edit > Lock Object Modes is ticked tick and if so turn if off. Save as defaults for future via File -> Defaults -> Save Startup File.
Add Ruth2 v4 mesh parts dev kit via File > Append Ruth2v4Dev.blend and select the “Object” mesh part you want to work with.
In Outliner, if present Delete Light and Camera.
In Outliner, if you have a mesh part named “headMesh”, it is just the Second Life/OpenSim classic avatar head shape for comparison purposes and not part of Ruth2 v4. Delete that too.
Rotate mesh 90 degrees on Z axis to face right in front orthographic view (as armature already is as you will see later when you append that).
Use Object > Apply > All Transforms to ensure all subparts of rotated outer container/mesh are transformed.
Add armature via File > Append avatar_skeleton_with_custombonesettings.blend and select “Object” avatar_skeleton.xml. When using “Append” in Blender always bring in the “Object” which will pull in any related items needed, i.e. to avoid confusion, you should not try to only bring in the separate “Armature” part in this case.
Select avatar_skeleton.xml and choose “Edit Mode”. Select > All, Armature > Bone Roll > Clear Roll.
Return to “Object Mode” and in outliner, select mesh first and then avatar_skeleton.xml. The armature must be the last thing selected. Then use Object > Parent (Ctrl/P) to get Parenting options. Set to “Armature Deform”. Parent should then be shown as avatar_skeleton.xml.
Now carefully check all the mesh properties as described in the Ada Radius guidance notes.
In the sample mesh part I was checking the Ruth2v4 (head, body and hands, no feet) had the required single Armature Modifier, but also a “DataTransfer” Modifier to Ruth2v4FeetFlat. “DataTransfer” and “Weld” may be able to be left in as according to Ada Radius… “those are Modifiers that do apply well on export from Blender and import inworld. Not perfectly, but well”. So I left that in. Ada adds…
The Data Transfer Modifier has several uses. In this case I use it for separate objects that we want perceived as a single object inworld. With the settings I used, it matches the face corner normals to the target we point it to. It works fairly well, depending on inworld lighting and how well the textures match. If you see a modifier called “Weld” it’s the same thing
Export to Collada
Select the mesh part you wish to export… note its the mesh part which is now parented to the armature… i.e. do NOT select the parent armature.
File > Export > Collada.
For rigged mesh items (like the Ruth2 avatar mesh parts themselves, or rigged mesh clothing) in the Extra tab you must ALSO tick “Keep Bind Info” (otherwise the mesh in Second Life/OpenSim will look like a spindly deformed alien when imported).
Import – Mesh Upload to Second Life/OpenSim
Import to OpenSim/SL via the Mesh Uploader as usual. Make sure to use the Second Life only version of the viewer (with Havok Physics) if uploading to Second Life. Make sure to tick “Include Skin Weight” in the Options/Rigging tab if it is not already preselected.

Note on Starting Apache Web Server via DreamGrid
On first and every subsequent startup two DOS boxes appear for OutworldzFiles\Apache\bin\rotatelogs.exe. Fred Beckhusen notes that Apache brings up two black boxes for the “loggers” – one for errors, one for activity which cannot be supressed. If Apache is installed as a service, the DOS log windows go away. This also lets Apache run your web page/blog/wordpress even if your grid is offline.
Also, there are two popups in OutworldzFiles\PHP7\ext\php_curl.dll for procedure entry point “libssh2_scp_recv2”. Fred Beckhusen points out that those error are from the OpenSim maps, which needs PHP curl. PHP will not run curl without loading a obsolete version of OpenSSL.

Now that Ruth2 v4 is released (see this blog post), it may be time to explore some of the clothing options available for her. Ruth2 is a low-poly open source mesh avatar for OpenSimulator and Second Life. There are a number shopping areas which provide “group gifts” free to anyone who is a member of the store group. Often group membership is free or low cost.
Remember Ruth2 v4 herself can be obtained at no cost via the Second Life marketplace or the inworld location…
Maitreya “Lara” fit clothing works quite well on Ruth2 v4, though not an exact fit. Using some alpha masks with the bakes on mesh body can be made to work pretty well. So start with Maitreya fit (or “Medium” or “Small” fit mesh depending on the style.
Join the Adamms Clothing group, activate the tag and look for the group gifts on the central plinths.
There is a large set of group gifts available in the centre of the store. Make sure to join the Seniha original group and activate the group tag.
Duck Girl Mesh Clothing for Ruth2. Use the “Ruth” versions where provided, or try the “Altamura” or “Maitreya” versions for close fit otherwise.
Now that Ruth2 v4 is release (see this blog post), it may be time to explore some of the clothing options available for her. Ruth2 is a low-poly open source mesh avatar for OpenSimulator and Second Life.
Remember Ruth2 v4 herself can be obtained at no cost via the OSGrid RuthAndRoth region. You can also find some teleporter boards to various OpenSim Hypergrid locations there… along in some cases with some preselected items from the many that are available. A number of useful additions, such as potentially relevant alpha masks” are also included in the selection boxes.

This page is to provide resources related to the Nani branch of OpenSim to assist in testing OpenSimulator. This branch is developed by Nani with support from Hyacinth Jewell of HG Luv Grid. Details of the Nani OpenSimulator version can be found at https://mosthugs.win/
Nani OpenSim was branched off from the OpenSim 0.9.1.0 Dev Master on May 5 2018. Nani release versions reflect the release date. E.g. 20.6.11.
An example Nani-based grid is Alternate Metaverse (AMV)…
Bakes on Mesh (BoM) on Nani Grids
The 8th October 2020 update to Nani OpenSim makes BoM work more compatibly with viewers that use Second Life/OpenSim 0.9.2.0 style BoM (left hann image). In Firestorm 6.3.9 and beyond users should see BoM equipped avatars correctly. Users using Firestorm 6.0.2 will see fall back coloured faces on BoM avatars (right hand image).
It looks like at the current Nani software release (8th October 2020) that a manual rebake is necessary if you change anything that affects the BoM layer, such as adding classic clothing items or alpha masks. So bakes are not being updated and pushed back to viewers.
There is a mechanism by typing /#bom me in local chat for you to let others around you still using Firestorm 6.0.2 to see BoM avatars. You see this message in local chat:
BoM detected! You may not appear correctly to people with older viewers. If you would like to use our bake feature... type in chat /#bom me ..and you will appear normally to people with all viewers.
There are a few glitches still with the baked head not working or not hiding the underlying classic avatar. But its getting there.
From 11th September 2020, OpenSim can be built using .NET 4.8 as well as the current default .NET4.6. .NET 4.8 and the necessary compiler tools can be made available by installing Visual Studio 2019 Community Edition.
OpenSim using .NET 4.8
Then use runprebuild19.bat and compile.bat
OpenSim using .NET 4.6
For continued use of .NET 4.6 OpenSim also needs:
Then use runprebuild.bat and compile.bat
Visual Studio 2019 Module Installation
Install individual modules at initial installation time or later via
Visual Studio 2019 -> Tools -> Get Tools and Features -> Individual Components
For Diva Wifi addon module language resources generation, you also need to ensure that the PATH environmental variable has resgen.exe and al.exe tools on the path.

Ruth2 v4 Revision 2020-09-02
Based on Blender Mesh from https://github.com/RuthAndRoth/Ruth2 (was Ada Radius Draft 11). Use a viewer which supports Bakes on Mesh, e.g. Firestorm.
Ruth2 is a low-poly mesh body specifically designed for OpenSimulator and which can also be used in Second Life™. It is built to use standard Second Life UV maps using a scratch-built open source mesh by Shin Ingen, Ada Radius and other contributors from the RuthAndRoth Community. Ruth2 v4 is the fourth version of the mesh avatar updated to be built and rigged using Blender 2.8 and with improved documentation of the workflow to make it reliably repeatable and credits to all the asset creators involved.
BAKES ON MESH
Ruth2 v4 is provided as a single mesh that is designed to work well with Bakes on Mesh. It has a simple alpha capability without needing separate mesh parts and alpha masks can be worn to give more control over hidden areas. rather than use Bakes on Mesh, skin textures may be applied, but you should then add a full body alpha mask to hide the underlying system avatar.
The “Ruth2 v4 – Mesh Avatar” box contents are designed so that they form a complete initial avatar using Bakes on Mesh. You can switch to your own shape, skin, eyes and hair and/or use the HUD to change your appearance. Some example hair, underclothing, hair bases and a range of alpha masks are provided in the “Ruth2 v4 – Extras” box. Skins as used in the HUD and more can be found in a “R2 Skins – Female” box.
Ruth2 v4 uses a single combination HUD, created by Serie Sumei, for alpha masking, skin and eye texture application, finger and toe nail colour, and other features. The skins and eyes that are available are set via a notecard (!CONFIG) in the Contents of the HUD which can be edited to incorporate your own skins (11 slots are available) and/or eye textures (5 slots are available).
The Skin Alpha Mode can be changed between Alpha Masking with cutoff=128 (the initial setting) and Alpha Blending. Depending on the Alpha Mode that is used on hair, clothing or other attachments that use partial alpha it may be useful to be able to change the setting used on the mesh body to avoid some parts not displaying correctly.
Ruth2 v4 – Mesh Avatar – This is the normal distribution box and is designed so that once unpacked its contents can be “worn”. It contains basic “classic” avatar shape, skin, eyes or hair to form a complete outfit, but these can be replaced with the users own preferred content.
Ruth2 v4 – Mesh Avatar Business – A special version of the Ruth2 v4 Mesh Avatar for G-Rated or Business usage is provided with a modified body shape and skins which have simple baked-on underwear.
Ruth2 v4 – Extras – This is a box of useful extra elements and options.
Ruth2 v4 – Resources – This box is not normally needed. It contains textures and other resources with original UUIDs as used within the other assets. This can be useful if moving the assets across grid, or to repair elements.
Ruth2 v4 – Mesh Uploads – This box is not normally needed. It contains mesh for all Ruth2 v4 elements as originally uploaded and before attaching a root prim or any texturing.
R2 Skins – Female – Skins and related skin textures as used in the Ruth2 v4 HUD and alternatives from https://github.com/RuthAndRoth/Skins.

KNOWN ISSUES AND TROUBLESHOOTING
Ruth2 v4 is designed to have low “avatar complexity” when worn to reduce lag. Asset sharing of the meshes and textures has been encouraged wherever possible with all assets made freely available to allow for reuse.

Linden Lab are moving Second Life from their own servers onto the Amazon Cloud – a process known as “Cloud Uplift”. This will take place over an extended period during 2020. Some regions are already operating “In the Cloud” on the “Aditi” Second Life test grid. See this Blake Sea is now up on Aditi – Second Life Blog Post.
Inara Pey, as often, has provided very helpful blog posts on the Cloud Uplift and her testing with her extensive range of vehicles to try out region crossing to see if that is improved.
Some Entry points on the Aditi test grid where boats and seaplanes, etc. can be rezzed to test are:
Blake Sea – Atlantic (secondlife://Aditi/secondlife/Blake%20Sea%20-%20Atlantic/245/219/16)
Supercar on Blake Sea on Aditi in the Cloud
Supercar looks fine in the Cloud and region crossing looks good. I deliberately flew into a region on a corner with void beyond, and not surprisingly found myself ejected with my vehicle safely returned to my “Lost and Found” folder. Supercar is rumoured to be capable of flight at very high altitudes at Mach 5. Other aspects of the test are “CLASSIFIED” 🙂

GenCon (https://www.gencon.com/) is a (normally physical) convention for tabletop gamers (like Duungeons & Dragons) with extensions to all sort of other role play games. It has been running since 1968 when it started in Lake Geneva, Winconsin, USA, and is usually held in Indianapolis. Due to CORVID-19 the even is being held virtually from July 30th to August 2nd, 2020. See https://www.gencon.com/online.
VRazeTheBar is organising a set of GenCon events on regions in Second Life. The Welcome Region is already open until July 30th at http://maps.secondlife.com/secondlife/Welworn/96/223/97 and will provided access to the multi-level gaming areas when the conference runs.

Mozilla Hubs is a virtual collaboration platform that runs in a web browser on desktops, tablets and mobile devices. It can support wireless standalone VR headsets. Desktop VR setups like the Oculus Rift are supported via a WebVR compatible browser (e.g. Firefox). See list of supported devices.
Simple 3D spaces can be selected from an initial range, or created in a tool called Spoke. Other users can be invited to join in the room using a shared URL. The room can have 3D objects, media and video screen facilities, etc.
Avatars are very simple and can be selected from a set provided. Default names are assigned to users unless the user changes that (saved locally on each browser used).
Lost Horizon has been created by the team behind Glastonbury’s Shangri-La festival within a festival, and in conjunction with VRJAM and Sansar to be “the world’s largest independent music and arts festival in virtual reality. Lost Horizon is a REAL festival in a virtual world. A fully interactive and multi-stage event to explore… raising money for The Big Issue and Amnesty International”.
ShangriLa – Glasto – Day 1 – July 3, 2020
The Tech: I was using Oculus Rift via Sansar to attend the festival. Access worked quickly and without glitches. After arrival at the ShangriLa entry portal, there were teleport portals to the four stages (Gas Tower, Freedom, Nomad and SHITV) and the Art festival area. The performers looked like they were performing against a green screen so they could be placed into the stage area of each performance space, and appeared as 2D video streams on stage. The stage area was unreachable by users so the illusion was maintained.
On entry through the portals to each stage or experience the user was placed in a sharded version of the experience. Users will normally end up in an arbitrary shard. Each shard had a Sansar official helper who was there to answer questions in chat (nice feature), a different official in each shard as far as I could see. There were perhaps 40 to 60 avatars in each experience, though a lot of NPCs were scattered around to make it look much busier. Voice was active in each shard so people could chat (or shout) over the music. Emotes can be used for dancing animations. The entry area can be bookmarked as a “Favourite” location, and if selected prior to teleport, the “instances” available can be listed along with the number of avatars in each, prior to selecting a specific one to enter. The specific instance URL can be shared with friends to let them join you without ending up in a separate shard.
The experience was very well designed and performed better in comparison to the VRChat-based Jean-Michel Jarre VR concert on June 21st, 2020 [See Blog Post].
ShangriLa – Glasto – Day 2 – July 4, 2020
The festival continues to work really well. It may be worth noting that larger performing groups need to be careful they don’t step outside the field of viewer before their green screen. Make some marks on the flor for the area covered by the camera. Otherwise the outermost performers can get clipped by the edge of the frame breaking the immersive effect, which is otherwise good, so long as you don’t get close to the stage and loom from one extreme side at an angle. Then the performers can look a bit flat 🙂
It is also nice that the community is not so large that you are likely to bump into old friends from Sansar, Second Life or OpenSim, which enhances the community festival experience.
