My polygons currently have 3 textures. Each is actually a small section of a larger texture. As I can select all 3 sections freely then 3 sets of u\v's *must* be in use.
Because I'm using animtexture I personally set the u\v's in the 0-1 range to show the whole texture and blitz works out the real u\v's internally.
This system only works with each of my tiles being a separate object. But I want to have multiple tiles in the same mesh, sharing the same surface. For this I have to do manually what Blitz does for me, and thus I need access to more than 2 sets of u\v coords.
