Apex cloth wrong computes vertex normals

Hello.
Using Apex cloth in my project, I ran into the problem of vertex normals on simulated meshes. When simulating, they look crumpled due to incorrect rendering of normals. I tried various methods of creating an apex file, importing a mesh, versions of the engine. The same problems are observed in the Content Examples project on some meshes. Is this a bug?

Hi, did you find a solution for this? strangely in Content Examples on my end (UE4.16) there is no problem with that particular asset, but I have problems with our own skeleton mesh. Vertex normals on extreme concave shapes just go crazy when unfolded, making big patches of strangely lit surface.

No, I stoped trying to figure out the problem. I decided to wait for new versions of the engine.

Yeah, hopefully it will be fixed. At the moment I’m tweaking each problematic vertex manualy to look ok when unfolded (they are ugly mess when not, fortunately nobody sees it :)) which is a pain. But at least it works.
