While I render just fine bump maps with the native maya renderer with mental Ray i can't see anything. I used a 5+ value for the Bump Depth (I even reached 50!!!) but nothing, then I entered some values in the Bump filter (between -4 and -7) but still nothing.
I use default maya shaders with noise as a bump map via bump2d
Any suggestions?
(Sorry for my english)
I have been this problem because a was using
multiple uv set .
And the bump can only work with
the default UV Set of an objet
Apply a good UV on the UV set Default and after U can
render your Bump.
Good luck
again sorry for my bad english
