Re: Indigo Renderer 4.0.38 Beta Release
yo,
when activating Clamp contributions, in GPU mode using 2 units, some squares are present in the picture (randomly)
if only one gpu is on it's ok
if clamp is off and 2 gpus are on it's ok

Re: Indigo Renderer 4.0.38 Beta Release
Contributions clamp is equivalent to denoise of Renderman and other render engine?
Re: Indigo Renderer 4.0.38 Beta Release
Did you try 1 unit with two GPUs ? Maybe they scale together ? I'm asking in the dark.

Re: Indigo Renderer 4.0.38 Beta Release
je suis pas sûr de ce que tu demandes, là... regarde la copie d'écran ci-dessus, il y a 2 contrôleurs gpu distincts, si j'active les 2 avec le clamp ça fais le damier, un seul gpu actif avec clamp c'est bon, que ce soit l'un ou l'autre gpu
1 unit = one GPU in my mind
I have two units inside this machine, if both are running and clamp is activated, i got check pattern, sometimes after 2/3 mins that dissapear but sometimes not

meant contribution clamping was sort of a parametric option, which setting I inferred to be susceptible to scaling with the number of GPU units running.Added controls to mode configuration area in render settings.
Sorry, that's what it is to shoot in the dark !

Re: Indigo Renderer 4.0.38 Beta Release
The GPU renderer uses tile rendering internally, and it seems there might be a problem with the brightness of the tiles when multi-GPU-rendering + clamping.

You hacker! :D I'm quite surprised that works to be honest.pixie wrote:kkkkZom-B wrote:Me too..... don't turn it on!!!! its my new favourite setting... myyyyy precious! :D
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!

So was I, namely because now I can't get the scene to load in neither windows linux or osx (fresh scene).Oscar J wrote:You hacker! :D I'm quite surprised that works to be honest.pixie wrote:kkkkZom-B wrote:Me too..... don't turn it on!!!! its my new favourite setting... myyyyy precious! :D

Hi
This scene is particularly suitable to test the novelty "Clamp Contributions".
Transparencies, reflections, refractions, colored shadows, glass material, and caustics. Sunlight hours pm. 14.30 yesterday the local meridian. Clamp contributions, active, Max contribution = 100.
Well fireflies are not there!

Re: Indigo Renderer 4.0.38 Beta Release
Could we have the "math" under clamp contribution?
My goal is to understand how far is an unbiased image with that parameter.

Re: Indigo Renderer 4.0.38 Beta Release
Create a specular material and set the desired value, compare it with the default, you'll see that the higlights will be dimmer. I don't know if that answers your question, but the practical effect is that it will 'wash' away the light reflections.Jay-ko wrote:Could we have the "math" under clamp contribution?

PS- having made the test I see that it does a bit more than dim the high lights, the specular itself gets darker.
Re: Indigo Renderer 4.0.38 Beta Release
@pixie> anyway, this very interresting. thank you!
I found a new feature from my side :p, afer a resume:
Then I opened the same igi file with 3.8.23 and I can save png and jpg without surprises.

Re: Indigo Renderer 4.0.38 Beta Release
BUG OSX :Transparent materials (if the have color ((tabulated data)) to them ) lose the color data if rendered on GPU.
Re: Indigo Renderer 4.0.38 Beta Release
yes, tabulated data is one of the few things still not running on the GPU.Originalplan® wrote:BUG OSX :Transparent materials (if the have color ((tabulated data)) to them ) lose the color data if rendered on GPU.
Its not a bug, but a missing feature :D
