Could you please explain it further?

Contribution clamping basically works as a firefly filter.

If it is enabled, and the max contribution is low, then it won't allow bright spots (fireflies) onto the render.
As the max contribution gets higher and higher, brighter and brighter spots are allowed.
So a max contribution of infinity corresponds to contribution clamping being disabled.

Since it is clamping bright spots, it does introduce bias into the render. Because of this it will be off by default. (We want Indigo to be unbiased by default).

However it should be a very useful tool for artists, to remove fireflies from their images in a simple and efficient way.

An example:

It is unbiased by default! Biased user interaction is needed to turn it on...

kkkk

BTW, through an hack I've made light layers to work on gpu, one must render it first on cpu, tweak the igs file so that it sets gpu, and then one resume the render and presto! Light layers!

Much improved from the first Beta build!!
CPU Rendering seems faster (LOT) then before.
GPU render (correct me if i'm wrong) feel and behaves MUCH smoother! Specially on startup!
Feels like data stream is much more optimized and more efficient then before.
AND Indigo (App itself) is remaining pretty responsive during GPU rendering, which is a huge plus!

-Clamp contributions : LIKE A DREAM!

And the many more improvements i didn't even get too.
All in all very solid build!!

@Ono my two FirePro's are sending you and the Glare team hugs and kisses they feel much cooler now. :D

Check out the test scenes and render times below from Oscar and Arthur.

the painting in the back is... ehm... black O_o
Is this issue repeatable?

Same issue with your scene on v4.0.37 two days ago. And actually with v4.0.38. For cpu is right.

Give me a sec to re render and check it. Mr Zom-B ^ . ^

Unfortunately it remains black, but texture seems OK.
I had this issue only with cutout materials on GPU (but that was because GPU didn't rendered alpha in 4.37.

The problem is not with your scene i think it's because you used a .png and maybe the surronding area in the pic is too bright (white) and it recognizes it as an alpha.? Not sure.

Yeah the black image is a bug to be fixed.
