Hi I have a different issue now, I've decided to try exporting some of the models to Blender.
However, I ran into the UV map problem. For reference, the UV map here:

Different colors for different UV channels it seems
When I export it to Blender, using the psk tools from
here, I get this instead:

That only the first channel is used is one thing, but the UV channels from the other materials aren't imported into Blender. Is there any way to work around this problem? I only use Blender though since I already used up my trial for 3ds Max and I don't want to buy it.
I used build 730 of UModel if that helps.
