Using Unwrap UVW with multiple texture files for one character

[Anonymous]

I have a character, but the texture is divided into two files. I added one unwrap uvw texture for torso. Now I need to texturize legs and arms from another file. How do I do  this?

So far for my character I made multi/sub material with 3 materials in one: face+specular+bump, torso+specular+bump, legs and arms + specular + bump. I have only one "unwrap uvw" modifier in stack now, it's set to work with torso texture so half of my character is textured, and I don't know how at the same time use the same uvw modifier to unwrap other textures for the same character.

When I try to switch to map channel 2 in unwrap uvw modifier for the second texture I get this message

So the answer is to bake unwrap uvw texture into mesh and then unwrap other textures.
