Short description of error
The UV Map node does not seem to give the correct results, no matter what UV Map is chosen.
Exact steps for others to reproduce the error
Open the attached file
Switch to rendered view (Cycles).
Note the while lines on the model.
Note in the material that the texture node set to "Panel_Lines.png" is taking input from the UV output of the Texture Coordinate node.
Change the input of the texture node to the UV Map node.
Note the White lines do not display, no matter what UV map you select in the UV Map node.
I believe this is incorrect behaviour. The texture coordinate node uses the default UV map. The result should be the same using the UV Map node when set to the default UV map.
