Female RPM Avatar Eye Deformation Issue with Viseme Animations

We’re experiencing an issue with our RPM character implementation where female avatars’ eyes become severely distorted (bulging/oversized). Here’s the specific setup:

  • Using RPM Character component to handle facial animations and visemes
  • The component manages:
    • Lip sync animations via visemes
    • Head tracking
    • Eye morphTargets for blinking/expressions
    • Animation state transitions (Idle/Talking)

The issue:

  • Male avatars render and animate correctly
  • Female avatars show extreme eye deformation
  • Eyes appear significantly enlarged and bulging out
  • This occurs consistently with female models while using the same animation setup that works fine for male models

Current implementation:

  • Using standard RPM character setup with skinned meshes
  • Handling morphTargets for eye animations
  • Managing animation states through useAnimations hook
