I first looked at VRChat on desktop and the Oculus Rift in 2014 (see this blog post). Things have moved on a lot since then. This blog post brings together some links and resources related to VRChat.
Note also that VRChat now uses the web site vrchat.com rather than the earlier no longer available vrchat.net.
Avatars can be created in a range of tools and made available in VRChat.
- Ready Player Me. See my blog post.
- Also MakeAvatar and Taffi.
- Uploading Your First Avatars (YouTube Video Tutorials)
As well as a wide range of environments or “worlds” created by others, you can create and upload your own environment.
