Hi community! I was just wondering if anyone has any tips to remove graininess from reflections when using PBR (or at least point me to a thread… I cannot seem to find one…) So far, it looks like I have had to do this to come kinda of close, but it kills my render times:

Pixel Samples: 32 32
Min Ray Samples 1
Max Ray Samples 32
Noise Level 0.0001

Reflect limit 1
Raytracing Bias 0.1

Thank you in advance!

I suppose you have blurred reflections? If so, try to increase reflection quality in shader, in case of default mantra surface shader.

You should not have to put your noise level to such a small value. Set your min-ray samples a bit higher (3 for example), and pixel samples lower.
Just pixels samples of 5x5 is often more then enough.
You could have a look at the material you are using for your reflections.
You might want to just take a bit more samples just for this single material and avoid an overall increase in rendertime.

Hope this helps a bit. If you post your scene we can of course be much more helpfull.

Hey guys thank you for the tips! I cannot post the scene unfortunately due to being from my work . However let me give these a shot and see if it works

The reflections are indeed blurry and I setup my ref quality to 10. The slider max). Perhaps I can try pushing is a bit further

Thank you for the advice!

Hey guys, is there a way to set a falloff for the reflection distance?! Say that after a certain distance from a reflective surface, the reflection rays get discarded to save on processing and render time.

Cheers
