So ok, I implemented both ways, for Max users, they can do the 'easy' method of importing .uvw files. Then there's also the fallback option to import/export using additional .obj files per uv-channel.
Also the number of provided options should give everyone the flexibility to use any 3D studio of choice.
Export works fully, import about 95%. Then the inevitable QA checks, and then release. ETA, probably a couple of days.
