[UV Packmaster] Efficient UV packing solution for Blender (C++ based, multithreaded)

Hey.

Whenever I try to use UV Packmaster on one of my more complex meshes, uvp.exe crashes. It just happened with the recent V2 demo in Blender 2.8, but it also happens with V1.91.3 in Blender 2.79.

Any ideas what this can be?
