Help: Noise in Interior Image

[braddewald]

I've been getting some really fine/granular noise that makes my glossy reflective surfaces look "snowy," especially if they have a dark diffuse color. The problem is always worse when I have a VraySky in the scene. I don't really know what's causing it and would really appreciate it if anybody could help me out. I've attached a screencap of the noise and of my vray render settings. Thanks!

Bump up the Global subdivisions multiplier. Most likely the lighting does not have enough subdivisions.

I think your interp samples are way to high also.

I´d leave the noise threshold on 0.005 but would take the adaptive amount down to 0.7. Good luck.

I noticed your AA filter is turned off? I've never seen it that way before, or heard of a recommendation to turn if off. Though, there's 1,000 different ways to render, I'm curious to why that's checked off. I don't think it's the problem, but it did stand out.

 

Sometimes, in interior images I've gotten around the sparklies by switching from linear color mapping to HSV. Linear can sometimes blow out bright spots, especially in the case of reflections of an exposed sky or a light near a surface.

Have you tried increasing the materials reflection glossiness subdivision?

 

I think that your render settings are way too high. This way you gain by 5% better quality picture in cost of plus 500% render time. Is it worth it? Increasing materials reflection glossiness subdivision should be more effective.

That's another way without increasing your overall setting.

Adding more light directing on the noise. (For these lights, you just increase the samples and decrease the brightness.)

Doing this should not increase the overall time to render since you didn't increase all the setting but just that area.

been doing this and it's help me alot. Hope this help.

Cheers!
