Component:SkinnedMeshPositioner
More actions
The SkinnedMeshPositioner component drives a slot's transform so it stays locked to a specific triangle on a SkinnedMeshRenderer.
Normally you can attach things by parenting them to bones, which works okay. But for parts of the skinned mesh that are weighted to multiple bones and/or are affected by blendshapes, this will cause the object to "drift/slide" relative to the mesh. This component fixes that by computing the transform from the actual skinned mesh transform![1]

ComputeParameters:ButtonEventHandler
|
ButtonEventHandler | ✓ | Calculates parameters to position the slot at its current position, rotation & scale, relative to the nearest triangle on the specified SkinnedMeshRenderer |
Usage
To use this component, you should position a slot so that it is placed where you would like it to be anchored on the SkinnedMeshRenderer, attach this component to that slot, fill in the Skin field with a reference to the SkinnedMeshRenderer and select the Compute Parameters button in the Inspector. Once pressed, Resonite will fill in the TriangleIndex field with the index of the nearest triangle on the SkinnedMeshRenderer to that slot, fill in the BarycentricCoordinate, LocalPosition, LocalRotation & LocalScale fields with the values to keep the slot positioned where it was, relative to the selected triangle, and set the PositionDrive, RotationDrive & ScaleDrive fields to references to the respective slot fields.
