Materials Showing in CPU rendering but not GPU Arnold rendering

[Anonymous]

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?

How big are the textures?

Any errors in the log file?

Hi I am having the same issue but in maya I was wondering if anyone had a solution?

Hello,

I was wondering if you had a solution to this as I'm having the same issue with gpu not rendering physical materials but cpu does fine.

Thanks.

Hi, I have had that problem too and I solved it by changing deprecated nodes for the new ones then it was solved.

In my case it was the old "layer_color" I replaced it with the new "layer_rgba".
I hope this helps,

Diego

Hi Diego,
what do you mean by "deprecated nodes"? Are you talking about Arnold materials? Are you saying you replaced the "physical" materials with Arnold Std surface materials?
Thanks.

Hi, I am relatively new in GPU rendering in C4DtoA and many of my materials that I had whit CPU stopped working in GPU, then I saw that it was because some of the materials had nodes from previous versions of C4DtoA and when I changed them for the corresponding current nodes they worked with GPU, it happened with Displacement node, Layer shader and some others.

im totally new with MAX and your answer was really good, thank you @diego6S3FN, yes i had to modify some of the materials, it helped... and then another problem showed up and now my HDRI picture and reflections are all blue.... ^^' but your solution worked thank you 🙂

I'm not familiar with C4D so I can't be much help. Cheers.
