Hi Szabolcs,

looks like you can do this,

In your mia_materials Anisotropy tab you should have a 'Channel' attribute. This lets you point to other UV sets than the default one.

0(zero) is the default UV set, 1 is the first UV set you added yourself etc.

If you hover your mouse pointer over the 'Channel' attribute in the Attibute Editor it says, "Anisotropic base angle comes from the U direction of the chosen texture space."

Other values you can use, anisotropy_channel can also have the following "special" values:

• -1: the base rotation follows the local object coordinate system.
• -2: the base rotation follows the bump basis vectors
• -3: the base rotation follows the surface derivatives
• -4: the base rotation follows a vector placed in state>tex prior to calling mia_material

Also have a look at these two threads for more info about MR and UV sets, http://forum.mentalimages.com/showthread.php?t=3906 http://forum.mentalimages.com/showthread.php?t=5695
