Does it recommend a specific Write Defaults setting?

It recommends choosing one approach project-wide (typically Write Defaults OFF) to prevent animation conflicts and undefined behavior.

How does it handle the 256-bit parameter limit?

It includes budget patterns that calculate bit usage for Bools, Ints, and Floats to ensure your synced parameters stay within VRChat's limits.

Can it assist with PhysBone configuration?

It offers clear guidelines on bone counts and collider limits to prevent your avatar from being hidden due to poor performance ranks.

Does this skill help with Quest optimization?

Yes, it provides specific triangle, material, and bone count limits to help you reach Good or Medium performance ranks on Meta Quest.

Game Development

Streamlines VRChat avatar creation by providing standardized patterns for Avatar 3.0, performance optimization, and expression systems.

About

This skill provides expert guidance for building and optimizing VRChat avatars using the VRChat SDK and Unity. It offers structured patterns for implementing Avatar 3.0 features, including expression menus, synced parameter budgeting, and complex animation layers. By providing specific performance metrics for both PC and Meta Quest platforms, it helps developers achieve better performance ranks through optimized PhysBones, mesh decimation, and material atlasing. Whether you are setting up eye tracking or debugging complex state machines, this skill ensures your avatars are performant, compatible, and feature-rich.
