johny, jure not believe talat'swords, is a fool! want our knowledge!!!

talats is dangerous, he speaks for 10 hours /day with me on the phone instead of studying kray!!!!

please Help them so I can return to my quiet life

[talats]

please Nico, be quite, or you'll finish to break my plane to make me say their secrets

At with % of luminosity i should set my lumiball?

Hmm i use about 200-400%...

[Janusz Biela]

Small update for You:

1/ Lumi ball outside (150-200% lumi with Sunsky or colour blue)
2/ Exponential 2.2 , recurse 20, Power in Kray 0.5-0.7
3/ If You have time please use QMC FG 800/0
4/ You must put Area Light in window light blue colour Inverse distance 2 fallow ~5 m with Power shader 1-10 (You must check: when scene is dark pleas increse Power Shader) of coarse inside room - NO OUTSIDE! just a few cm from window
Area light is for increse brightnes inside becouse 200% lumi ball is too small (but we can`t increse it becouse You recive too strong light near windows area.Second : from Area You recive good shadows and after that You don`t need Strong setup FG in Kray. Jure show You
oversample command (this is the best in this moment) interior renders are CREAZY FAST"
http://www.kraytracing.com/forum/downlo ... &mode=view under 4 min on my 8 core.
When You use oversampling You don`t need Strong FG (sometimes enough is 200/400!)
AA is much faster - becouse is small FG, blurr much faster becouse FG is small etc, shadows GI much better becouse You recived extra samples etc...

5/ Desaturate shader on the floor (50-100%)
6/ maybe extra window from backside or left/right side camera
7/ maybe extra light from lamps (IES, spherical light in lamps etc...)
8/good texturing (dark surfaces 50% diffuse, bright surfaces maximum 80%)
9/ good idea how make light inside

[talats]

This is my last render (about 45 minutes) and all the settings. I'll try later your settings.

[talats]

Jhony, with % the area light in the window?

[Janusz Biela]

Jhony, with % the area light in the window?

You must use EXPONENTIAL without LWF.
Area light depends effect. You can use 100000% with 0.001 m
oversamling info please read up from Jure.

[talats]

That's the last render made with parameters of Jonhy about the lights and of Jure about the FG...
The light now it's better, but I still have spotches in the corners.
Time rendering 21 minutes.

Here we are...

same lighting of image below, 600000 photons, FG from 1000 to 2000, AA Hight. 34 minutes of rendering.

Ok the settings look good. But you have this big over bright area on the ceiling which looks really bad. You also need to tweak your surfaces now because you have some surfaces completely black and some over bright... Keep working, you'll get there!

Which are the surfaces completely black and which completely bright (except the ceiling)?

[Janusz Biela]

You have overbright ceiling and sun area on the floor.

prerender 1,2,0.01;gradients_neighbour 0.1

What does it means? And what it does exactly?

[Janusz Biela]

prerender 1,2,0.01;gradients_neighbour 0.1

What does it means? And what it does exactly?

better is:

prerender 1,2,0.05;gradients_neighbour 0.05



switch`s prerender:

1 - percent detection (1 is 100% , 0.5 is 50% of all samples) best is 1

2 - how many passes (1 is default , this no work, 2 is two passes - You recive extra samples), I thing 2 or 3 is maximum

0.05 - treshold of detection (smaller bigger dettection)


gradients_neighbour 0.05 - blurr engine for samples (0.1 small blurr but faster render, 0.01 stronger blurr but slower render)


Now when You recive new extra samles You can use smaller FG in Kray for example:
prerender 1,2,0.05;gradients_neighbour 0.05 You can use FG 200/600 min/max spacing 40/1000 , FG blurr 0 (or small 1-2)

Now render is very fast (becouse You have small FG) and You have good GI shadows silimar to QMC.
Of coarse You need experiment with this. You can use 10 passes:
prerender 1,10,0.05;gradients_neighbour 0.05 and after that very small FG: 10/50
And ultra fast AA and blurr becouse AA depeds from FG (small FG - fast AA, blurr etc...)
