I set up a skeletal group in Matinee.It moves the skeletal mesh and plays a anim squence in the meantime.There is another skeletal mesh stands in its way.This skeletal mesh just plays a anim squence and it’s not in the Matinee.But the first skeletal mesh just passes through the second one with out any overlap or hit.These two skeletal mesh are from the AnimStarterPack so the physics asset should be OK.And I leve the collision preset as PhysicsActor and check “Simulation Generates Hit Events” and “Generate Overlap Events” check box.
