"exsposure" is mainly to set the bright parts of the image and gamma is to set the dark parts. Try that and you will get much better images It's a missunderstanding that gamma "should" be at 2.2 Also use Cone filtering at 1.5 + Fullscreen Grid AA 3 to get it fast and nice. The im...

Thanx for the feedback guys. Yeah i was a bit surpriced myself since kray is single threaded Yep will try grid3 + limidr; and increase blurrays and then post the scene here.

Inspired by some modo scene. Hdri only, stochastic AA.

oh and captain, i see you use old 1.611. Try 1.612 wich i dont think have those black little squares bug.

Quick and dirty explanation: 1. Create an irradiancemap by using precomputed and be sure it saves to disk. 2: Copy that file and be sure your 2 started lightwaves point at each of the GI files, NOT the same file. 3. activate save GI both so it will both read data from the GI file + update it with mo...

Very nice! Maybe some more translucensy on the green leaves would make it even nicer

From the manual:
"smoothprecachescale ratio"
This sound to me like an very important function wich i guess highly affects quality. I would like this function abit further explained if possible.

From the manual:
"postprocess autoexp,strength"

I would like this function a bit better explained since i really dont understand how to use it and when. Maybe some examples could clear the smoke.

Wow that could be an interesting shot when it's done. Is all Glasgeomtry singlesided? Have you turned off FG reflections/refractions? It looks like that since the glass is pretty dark and it shouldnt. Always leave FG trans/refr on. The squares you see is probably a documented bug that i guess comes ...

Nice to see that you got such a good result with standard settings in Kray. Great render and design.

Looks very good. Is that a combination of arealights + radiosity?

Welcome and nice to have you onboard Marky!
I have also read it a couple of times
Are you saying that the multiply function isnt working properly, that there is a bug in the way it calculates and therefore get's to dark?
OR
Is the multiplied surface cancelling Sunlight and skylight?

I just want to fill in that this type of lowlight setup will take ages to render in any renderer. Nice images and thanx for sharing pienri.

Nice to see your example. What values did you use? Have you used your usual well proven technique with photonmapping? 6Hrs sound very long and i miss shadows around/behind the paintings on the wall.

Final! for this little tutorial anyway. Thanx for being patient with me.
I upped FG to 4000 and rendered with undersampling 2 fullscreenAAx8 - 46minutes.
