Animation System Gotchas

• general
  • a mesh can have either morph or skeletal animation, but not both
  • only one morphanimation (with hardcoded name "default", get with: entity->GetAnimationState("default")) per mesh, blending multiple morphanimations is not supported
  • bone rotations are blended as follows:

    Quaternion q1 = Quaternion::Nlerp(Quaternion::IDENTITY, rotation1, weight1);
    Quaternion q2 = Quaternion::Nlerp(Quaternion::IDENTITY, rotation2, weight2);
    Quaternion blendedQ = q1 * q2;
    

• d3d11 and gles2 rendersystem
  • maximum number of bones per skeleton: 40
  • uses indexed vertex blending
• psp rendersystem
  • maximum number of bones per skeleton: 8 (limited by the hardware)
  • no indexed vertex blending (not supported by the hardware)
