try these unifed settings:
min2
max100
quality 3

User shaders are buggy. they don't play nice with unified sampling. specially environment shader, bump up the samples to 32 and try a unified setting of: min of 1, max of 32 and 2 or + for quality.

If it's not enough bump up the max value.

Don't forget light relative scale.

Thanks for tips, 100 samples on unified and light cleared most of the noise. But I don't think it should work like this, probably this shader is bugged.

its working correctly. you always need samples (local) to solve noise for user_ibl. or what are you expecting?
the builtin_ibl is working better with unified (and because it prebakes the env compared to user_ibl), but you also need more samples to solve the noise.

your unified samples were really low, to low to solve things that needs more rays to cleanup. and you cant replace these low samplevalues with a high quality value.

Here my test with 32 samples in the ibl env, and 1-50-2-0.02 in the unified sampling ones.

Nice,

so I've made a test with these settings and...

Oh snap

you have to use your own settings to get good quality, there are no general good settings for all situations.

and can you show a 3dview snapshot of your scene? it looks like there is shadowing everywhere in your rendering, so i am right when i guess you are using objects around that are casting shadows? if yes, then you need more rays to solve the shadowing, especially with your hdr with nearly uniform lighting.

Send the Scene. and check your Linear workflow, I saw that it isn't set correctly.

Nox · Post by **Nox** » 18 Apr 2013, 22:12

Linear workflow is not set for this, yes. Scene very is simple (uploaded here).

here: http://www.sendspace.com/file/q2xwy6 I used an SIBL HDR. bump up unified sampling to 1-50-4-0.02

last one looks better, quality is more like i would expect. ;)

Thx, I found that turning on linear workflow helped to clear most of the noise. O_o

Guys I just made a video on the shader, really basic, to get people started.
Cheers.

oh dear, someone still use this thing? ;D

Isn't better to use sIBL?

more like is better to not use MR at all
