What are the uses of a topology 3D model for VRChat?

A topology 3D model for VRChat creates optimized avatars and environments that run smoothly, animate naturally, and support VRChat’s real-time social VR experience. It ensures avatars deform correctly with movements (like facial expressions or gestures) and keeps polygon counts low to prevent lag—critical for seamless interaction. For new creators, quad-based topology (avoid triangles in bending areas) works best with VRChat’s rigging tools, balancing detail and performance.
