Ahhh, sorry, didn’t mean to provide an improper response.
I actually don’t know if you can make the collision show up with faces. The mesh-outline does detail the faces, but past that you don’t get much from collision except what channel you hit on, the thing you hit, and the results from breaking that hit…
Can you make a duplicate mesh in the form of the collision-mesh and turn it on/off? IIRC the collision is just that, only collision. It’s not a mesh like in the sense it has materials, etc, it’s really more a volume one tests against vs intent-to-draw. A regular mesh would be draw-able like you want (If I understand correctly).
