Help ripping Xenoblade 1 (Wii) Maps

[Sir Teatei Moonlight]

Can you please clarify what you mean by that? Obviously their UV maps are wrong, but I'm not sure what that has to do with layering different textures across each other...

explain through example: the Bionis' right arm

   
so here's the right arm without any snow textures

   
this is snow texture 1

   
this is snow texture 2, using a different UV map on the same mesh

   
and this is them layered together for the final result

if you use the same UV map for both textures, one of them will be wrong, and so the final result will be wrong
