how to reduce noise in these glosssies

this is for animation - there’s too much noise in them glossies

have tried medium-animation and high-animation IR maps

brute force: subdivs 12
DMC: noise 0.005, multiplier 4, min samples 12, adaptive 0.8
(mitchell netravali aa)

I can’t seem to get it any better than what you see
I wonder if its because of a medium res HDR used for reflect environment
(but of course to change reflect map will alter the look, which I can’t do )
otherwise lighting is spots and some environment skylight

any tips?

Higher material Reflection Subdivs?

Lowering the DMC noise threshold and increasing the max subdivs for your AA should provide you with cleaner results, just make sure you are using ADMC AA.

DMC: .0001
ADMC AA: 1, 20-40

These values work for me most of the time.

this was my first thought to.

my reciepe:

ADMC image sampler, AA filter off (for stills)

sampler settings: min 1, max 100

noise threshold: 0,001 - 0,01 (noise vs. speed setting)

and for color mapping: don’t affect colors on, otherwise noise in shadows will stay, because of linear gamma correction.

pushing the material subdivs worse for rendertime than universal settings, because it “brute forces” everything then, universal settings only slow down for the noisy parts, that’s the beauty of it.

Yep, did a quick test raising the material subdivs here and it had no effect. I always use the Universal method because it always works, although it might be a bit slow for some people. Tried the Universal and it cleared up the noise great with the don’t affect colors:



thanks guys - that’s certainly the solution - perfect

but .. it hits my render times too hard!
I have to do HD render and frame time goes up by a factor of around 4 however much I massage the settings - the frame gets a lot more of the blue ribbon later - and there’s no budget for external render farm

so back to adaptive image sampler..
but 0.003 in dmc and don’t affect colors is an improvement
