Hi everybody!

I’m trying to smooth the ColorRamp gradient I’m using in the background for this image, but I have no idea how:

I’d like to smooth this gradient here:

I’ve changed the amount of samples, switched 8 to 16 bits, tried different image formats, used the denoising pass, but nothing. I’m pretty sure it has to do with the nodes setup I’m using

Does anyone know what could I do? Maybe another nodes setup to generate spherical gradients for the background? Any other idea?

Thanks!

Is dither activated?

@CarlG Genius! :slight_smile: It worked! I’m doing my first steps in Blender and I didn’t know this option. Thanks.

This happens with bit depth clipping. The render will come out in linear space and when converted into sRGB, it will lose color range, and thus the smoothness and result in the banded look that you see. High bit depth images such as EXR, HDR, and other formats that support more than 8 bits per channel suffer less.

Thanks for your answer @ajm, next time I’ll try those formats too.
