Unintended realism of dust specs

[Streetwise]

I've got an issue of white dust specs showing up on the surfaces of some furniture. I'm on 3.30 at the "default" settings, but using Adaptive. Seems like there was a check box somewhere that fixed the firefly issue, but I can't seem to find it.

Thanks.

I think you are looking for "max ray intensity" under Global Switches

Thanks. I see that it's already checked and at 20. I'll have to mess with that.

I get these annoying specs from time to time when using GGX brdf.
Everything else in the scene is nice and clean, but one or two ggx shaders just can't lose those speckles, especially at glancing angles.

Using crazy high min shading rate seems to clean them up.
Haven't tried max ray intensity

Im not 100% sure but it might be the same issue i had here: http://forums.chaosgroup.com/attachm...0&d=1458057964

Specially with GGX, if i use ward or blinn it's way faster to clean them up.

I've always found i get this if there's an over bright texture in the scene, so for example an image with it's output cranked up too high. You can either find the texture causing it (if that is the case here) or if you're really struggling you can turn on clamp output and set the value to something like 2.0 (<- this is a last ditch resort, avoid this if you can. You will lose any range to your final render)

It might also help to turn off "reflective GI caustics", seeing as how the speckles appear close to very reflective objects.

No luck with that, Vlado. I ended up cranking the min shading rate from 6 to 12 as Viscorbel suggested. That solved the issue for me.

Thanks.
