Context and Problem Statement
Yin works a lot in webxr, and noticed in the avatar ecosystem (VRchat, secondlife, etc.) most of these avatars are too high quality.
What tools have we come across that have enabled lightweight avatars?
Describe the proposed option and how it helps to overcome the problem or limitation
To try to make things work for webxr, yin is interested in lightweight avatars in as many ways as possible. exploring avatars that are as parametric as possible.
Describe how your proposal will work, with code, pseudo-code, mock-ups, or diagrams
Find ways to define volumes as parametric, and textures based on vectors instead of bitmaps.
Frame time: Using a mobile chip gives less headroom re: polys that can be dropped. Download sizes. How long does loading take.
Yin doesn’t love blender, more focused on web based tools fit for mobile processors and reasonable download speeds.
Yin has been looking into procedural materials as a lightweight mechanism.
There are two systems, skeleton system and blendshapes. Conversion of blend shapes to skeletons is possible.
Can also describe a quad subdivision workflow.
- quad based subdivision of detail
https://github.com/godotengine/godot-proposals/issues/784 - procedural materials
- bake blendshapes to skeletons
- Fire is researching CSG based extraction combined with sliders. https://kacperkan.github.io/ucsgnet/ https://github.com/eliemichel/DagAmendment
Positive Consequences
Works on the most widely accessible HMDs.

If this enhancement will not be used often, can it be worked around with a few lines of script?
Heavyweight avatars is a systematic problem.
Is there a reason why this should be core and done by us?
Avatars is our special area.
