How to use:

• Add the "Geometry Cache Decal" component as a Child of GeometryCacheActor.
• Attach decals in Unreal Editor

1. Set decal material.
2. Set decal generate-type as "BoxRegion" or "UVRegion".
3. Adjust the decal's region until it matches your needs.

• Attach decals at runtime

1. Call the blueprint function "LineTraceAttachDecal", the decal will be attached to the line-hit surface of the Alembic animation.

Precautions before buying:

• For GeometryCache with multi-tracks, you may need to reimport your GeometryCache with "Flatten tracks" checked.
• Generate decals in "UVRegion" only works when your alembic animation has continuous and uniform UV information.
