Apex cloth collision with scene objects

I finaly managed to get some apex clothing up and running. Collisions with the attached skeleton are also working fine. However, I would also like the clothing to collide with other rigid bodys and colliders in the scene.

Another member is talking about that problem here: Apex cloth does not collide with objects in the world - World Creation - Epic Developer Community Forums

It seems to me, that he somehow got it working. But I can’t figure out how he did it. Can somebody shed some light on that issue? Thx in advance.
