Bad material on mesh

Hey guys!

I have small problem here. Do anyone know, why my material on new mesh looks like this? Material looks good on other meshes, and I don’t think that I exported them before with different settings…

It looks like an issue with UV’s, it might be related to lightmap UV’s

Actually, they were not lighmaps, but you guided me on the right path. Somehow the second empty set of UV maps sneaked into the mesh (I probably did it myself, but I do not even know when, stupid me…) Many thanks!
