I have a 3dsmax scene set up with Physical Shaders built on PBR material approach. When I render the scene in Arnold using CPU rendering, it renders perfectly fine. When I switch over to only GPU rendering, the actual textures are NOT rendering. Almost every object in the scene is white. I tried converting on of the Shaders from Physical to an Arnold Shader type using Arnold Standard Surface. I then put all of the appropriate textures in the respective slots for normal, reflection, diffuse etc. Still, the textures do not show. What am I doing wrong?
