How do I remove noise/grain in water reflection?
« on: January 20, 2019, 09:23:08 AM »
I'm having a senior moment but I can't remember how to remove noise/grain from water reflection.

There is a thick bank of cloud that is being reflected but this is already at a fairly quality (2).
Render is set to 0.7 Md and 5 AA.
Is there something in the "Render subdiv settings" maybe?

Scratches head, maybe a second cup of coffee would help ...

thanks

“Defer all shading” in render settings should allow anti-aliasing to clean up the noise. The noise itself might be caused by voxel scattering quality (GI Settings), ray marching quality (cloud) or atmosphere samples, but in any case deferred shading with high AA should take care of it.

If using path tracing on surfaces, deferred shading is used automatically.

Thanks that seems to work.
Hmm, I had that enabled in an earlier version. Must have switched it off for a speed check and forgot to re-enable it.
