I'm encountering instances where my objects are showing banding after rendering in both 16 and 32 bit at 300+ resolution. I'va attached a photo of whats happening. Is it a issue with the 3D model export type from Photoshop?
This glitch is known and it happens with 3D Object that are created in Ps and imported into Dn. Something wrong with lights effects (as I know, and image mode) and there is some suggestion to make light adjustments (color range also) in Ps before exporting.
