3D model eyes often look weird in VRChat due to poor eye rigging, misaligned eye tracking, or unoptimized shaders/textures that break natural appearance.
- Poor rigging: Incorrect bone setup makes eyes move unnaturally—VRChat needs precise rigs for lifelike motion. - Misaligned tracking: If eye bones aren’t placed right, the avatar stares incorrectly or fails to follow gaze. - Unoptimized shaders/textures: Low-quality or incompatible shaders remove depth, making eyes look flat or fake.
To fix, recheck eye bones in Unity or use VRChat-friendly shaders like Poiyomi to resolve alignment or texture issues.
