I'm testing out Arnold for a project which will require a lot of volume rendering. Ideally would like to be able to do it on GPU. I've created a test scene using the WDAS cloud, following https://docs.arnoldrenderer.com/x/2IaMB
I've rendered out a frame using CPU, and then GPU. The only difference between the two is the device.
The CPU frame looks great, the GPU one looks pretty bad:
Is this a limitation of Arnold GPU? Or is there some additional setup required for rendering volumes on the GPU?
