sorry for the late response
if I understood the question correctly, then:
I am using it for some distant decorative models (these have other options like CanCollide, CanQuery and CanTouch false, if they are meshes then RenderFidelity performance and CollisionFidelity box)

If you want to see the game im using it for, here it is: (it’s private at the moment however)
