VRChat Avatars Skill

Version: 1.0 Stack: VRChat SDK, Unity

VRChat's performance ranking system means avatars ranked "Poor" or "Very Poor" get automatically hidden by most players' safety settings — your carefully crafted avatar becomes an invisible robot silhouette. Too many materials break batching. Too many bones eat CPU. Mixed Write Defaults cause unpredictable animation behavior. And Quest has dramatically stricter limits that require a separate build, not just the same avatar with fewer polygons.

Building within Good rank limits from the start means your avatar is actually seen by other players. The parameter budget and PhysBone limits aren't arbitrary — they're the line between visible and invisible.
