I have a Maya 2018 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?
Check the Arnold log. My bet is that you are using shaders that are not supported on GPU
Used Aistandart Surface
With sub-textures and just color.
Where can I see the registry of working nodes by textures?
For Ass and GPU to work fine?
And how are these textures and sub-textures loaded? What shader nodes are you using?
Please check the Arnold log for errors and warnings.
Where can I get a detailed Arnold log?

See the sidebar
And if you want to know what shaders are supported on Arnold GPU, see this page in the MtoA documentation: https://docs.arnoldrenderer.com/x/sYwsBQ
That page has links to a list of all supported features.
