TOptional< TArray< TPair< int32, FCollisionResponse > > > ShapeCollisionResponses
Remarks
When per-shape collision responses are changed at runtime, state is stored in an optional array of per-shape collision response settings. If this is not set, the base body instance's CollisionResponses member is used for all shapes.
