Ptex diffuse

The exported paint layer from Mudbox does not display properly.

Paint colors in Mudbox.



Mental Ray render once the Ptex map is applied in Maya.



As you can see the vector displacement map works fine.

I had to apply a Mental Ray 'Physical Sun and Sky' to even get to see it. Without this setting, it just renders black. (Alphas were the only proof that it was rendering)

This is the Hypershade, Am I missing a node?
