Blender + APEX SDK cloth: collision problem

I’m trying to to import a character with APEX cloth into UE4. I’m using Blender and the APEX SDK clothing tool. I’ve seen all the tutorials but I’m still having a problem with the collision in the clothing tool. Generating convex collisions for all or some of the bones results in an error and doesn’t work. Generating capsules doesn’t allow for enough precision and the cloth always ends up inside parts of the mesh that weren’t covered by the capsules. Any tips ? Can’t I just work with the mesh itself as the collision volume or import a proxy version with much less polygons ? Is the collision information for the cloth imbedded in the .apx file exported from the apex sdk or is it recalculated again in unreal when I generate a collision volume there ?
Thanks :smiley:
