Holy crap, I just noticed one hour ago there's a Save/Load option in the UVW unwrap modifier that saves or loads uvw's from a *.uvw file. Why did nobody tell me!!! :rotfl:
It took me 30 mins to debug the file in a hex editor, change my exporter in another 30 mins and bam, instant multi UV data into Max.
Crap... :rotfl:
On a side note, this obviously won't help users that work in other 3d studio's, so my question is, are there similar functions in ie. Maya/Blender?? If yes, I prefer going this route instead of multi obj-files. All you need is one obj-file, and one uvw file (regardless of number of channels as far as I can tell now)...
I find this very humorous and annoying at the same time... So Maya/Blender users, please look for a similar function and let me know...
