    How do I get a shader to use multiple UV sets (exported from 3d max)? I've got one unwrap that tiles diffuse and uses overlapping UVs. On the same object is a second UV unwrap for the light map. When I bring them into unity, both the diffuse and the light map are using the same UV channel.

    See the documentation on using two UV sets from 3dsmax.

    Basically, current FBX exporters don't export UVs correctly if the material in 3dsmax is Shell type; or if the material does not actually use both UV sets.
