Hello,  
I am relatively new to Maya, and am still better at modelling in Lightwave than in Maya.  
So I am attempting to import models from LW in obj format. Problem is, it seems impossible to apply bump&nbsp;maps to these in Maya.  
I double checked by creating a simple object in Maya, exporting this as obj to LW, then re-exporting it as a new obj from LW. This object happily accepts a bump map once imported back to Maya! So there must be something fundamentally different in the way the objects are created.  
What am I missing?

Any help would be greatly appreciated.

No, it doesn't. I have even gone down to the&nbsp;lowest possible complexity and tested with a non-textured cube, but to no avail.
