Diifrent UV for diffrent channels

[mart1jn]

You can mix textures by enabling "Mix textures" in the texture tag. Don't enable this for the first texture.
You can have more UV-tags on one object. A texture(tag) will use the first UV-tag to the right of it. (If there is no UV tag to the right it will use the left-most one)

So in your case it could be:
color-texture(Mix Textures off), UV-tag for the color, bump-texture(Mix Textures on), UV-tag for the bump.

Hope this helps

cheers

Thanks! I did tags and two materials, one for color and one for bump. I checking export to OBJ, but when i import OBJ to 3dsmax and see there UV channels, i see only first UV map. How to store model with 2 UV maps?
