Hey there, I also tried in the 4.15 preview 4 and the problem remain. I went to the most simple way to minimize the possibility of having problems, and I still have the same problem. I made a simple cylinder in 3ds max 2017, give it 1 bone, skinned it, applied the apex clothing and started drawing my max distances, exported both the mesh and the physx file. Once applied in the engine, it just breaks and does weird stuff.
