For Vircadia. Please fix.

The Hifi and Vircadia avatars are both not compatible with Hifi/Vircadia.
The bone naming is incompatible and the .fst doesn't remap them.
The best way to fix this would be to rename the bones in Blender according to: https://docs.vircadia.com/create/avatars/avatar-standards.html#skeleton

Keep in mind that an fst file is optional and only needed for remapping bones, attaching scripts, or adding "flow".

Upgrade Blender-chan to version 2.93 and make Blender-chan compatible with every known platform where 3D models can be used, both in Virtual Reality and Augmented Reality.

High Fidelity: Vircadia / TivoliVR / Overte

Probably a rebuild from scratch? instead of making the current model and bones HiFi-compatible, take and analyze an existing working HiFi-compatible avatar and go from there? Memo: where exactly is the "good" HiFi-avatar?

Unity: VRChat and ChilloutVR

The HiFi bone names shouldn't interfere with Unity. After model is imported, expressions can be added from the SDK packages.

Godot: V-Sekai

I am not sure where I can find an SDK for V-sekai. Perhaps this is similar to Unity with VRChat?

Virtualcast / Cluster

#4 #7
Generating an VRM should do the trick for both of these. As a matter of fact, a single VRM could work for many of the AR applications as well.

New functions

・Has every splashscreencard included from the pre-open source era (Blender v2.01 beta) to present (Blender 2.93 LTS)
・The splashscreencard carries information about each version of the Blender.
・The avatar also carries information about the History of the Blender Foundation, along with the logos of NaN and old Blender artworks.
・Blender 1.60 field/UI 展開

Blender History

Amiga Ball of 1989 with snakes → raytraces into Traces logo (indicates where the camera is) → NeoGeo Logo
Traces logo → Blender version 1 logo

Cluster is not available on Linux so this is going to be a pain to implement.

Generating a VRM file should do the trick.

When exporting an avatar for Hifi it makes sense to embed the textures. This makes it easier to use and faster to load.

Here are some example export settings with some explanations:

• (1) You should save your settings in a preset to make it easier to export the avatar for testing. (This preset does not update and has to be overwritten when you change something)
• (2) Setting the "Path mode" to "Copy" and checking the box next to it, embeds the textures into the exported FBX file.
• (3) Blender adds leaf bones by standard which are useless, make stuff more confusing to work with, and I think even get updates through Hifi's avatar mixer and therefore use slightly more bandwidth.

Please.
