Hello, I am very much new to Maya, just switched from Blender. I am facing a problem which I am not able to solve. The problem is some of the Mental Ray materials are not working for me. For instance I can successfully use Mia Car Shader but when I try to apply dgs material for my objects, I get error while rendering and the objects with dgs shader doesn't appear in rendered images. When I click on Mia Car Shader it instantly appears in Material Tab in Hypershader but dgs shader does not appear in Materials Tab. Please look at the video I am uploading with the thread to see what I am trying to say.
