Ok, so i've been looking all around the web on how to do this and i can't find any working method. I've tried using the tool made by Prall but doesn't seam to work.
I tried to find any information on how to use the export tools supplied with the Source SDK but couldn't find anything.
I'm running the 8.5 version of Maya. If anybody knows how it's done i would be verry happy if you could share that information with me.
Worst case scenario i'll have to learn XSI instead, since this is what valve uses and i guess it works way better
