I’m desperate because in my renderings i’m constantly getting paletted gradients instead of smoothly dithered gradients. It happens especially when i try to render slighty bowed surfaces, regardless of the renderer / render settings / Materials and light sources. Saving to 16 or 32bit depth won’t change anything.
I know MR does ignore the Dithering settings in the preferences, but its almost the same problem with the scanline renderer.
In the attached rendering i increased the contrast in Photoshop to make it more obvious.
Any ideas on how to get smoothly dithered gradients are highly appreciated =)

I can’t reproduce your problem. Maybe you could attach max file.

I believe the Gradient ramp procedural map is an 8bit map, so you’ll always get banding like that. Best to make a gradient in photoshop instead on a 16bit image if you see banding.

Hey guys, thanks a lot for your effort in hunting down this phenomenon.
I attached a simple Max9 Scene with an Omni Light and a slightly bent Plane with a carpaint Mat applied. When i render the scene i receive those non dithered gradients no matter which settings i use for MR.
@ Neil: I’m not using a procedural gradient map anywhere in the scene. It even seems like the artifacts occur regardless of the render settings, materials and light sources.
Any suggestions are highly appreciated !
thanks,
Rasmus
