Photon multiplier shader issue

[mathewlp_forum]

Hello ladies & gentlemen!

I'm trying to illuminate a scene with just one source of light coming from my ceiling.
I use material 100% luminosity, with shaders Indirect rays multiply and photon multiplier but I still can't get a good result...why
help please!!

[mathewlp_forum]

More information:

LW 9.6
Kray 2.0
Photon mapping Lighmap
FG preset High (without AA)
Tone map exponential 1.5,1.5

I'm would like to get better contrast results for the walls, see attached pict. (This render is without any shaders,with many light sources and with skylight)

Could You share Your scene with laps and without furnitures (only basic walls + lws)
I will prepare this for You and share on forum.

[mathewlp_forum]

All right...let me 10 minutes

the aim is to illuminate this scene as it should be in reality , it means without exterior natural lights and without reflection blur on the walls...

[mathewlp_forum]

Ok here is the scene + my render (medium preset)

thx

Please find atttached the ceiling drawing completed object file with all lighs. (material lights)

Tips:
1.Forget Lumi poly (better are Area lights) btw. Power on Lumi surfaces don`t work (bug in code)in Lighmap mode, but Area works ok.

2.Add evrywhere Area Lights with difference power or without (windows, small lights, kitchen lights) sometimes for small lamps Power Shader 100 is not big and can increse brightness in rooms from small lamps.If You recive Light Splotches please increse PhotonNumberMultiplier - 500 is good but sometimes this need change to up: 20.000.... or biger.

3. Don`t change EXPOSURE (always 1.0)

4. If You have dark area don`t tweak setup of Kray - just drill new window or add lamp.

5. 15-20 bounce light is minimum for good warm colours

6.If You need stronger contrast please decrese PARAMETR in Exponential (1.6-2.0)

7. If You use Power Shader You don`t need strong setup blurr (200/600 is very good)

8. FSAA G4 BOX 0.7 for me is the best AA wit limitdr.

9. IMPORTANT: don`t use Specular! please....

Great!!!

You help me a lot with all theses tips I THANK YOU VERY VERY MUCH

nice render!!

I'll show you my final render...

Yes becouse empty rooms are ugly

[mathewlp_forum]

lol right!

Euhhh after openning your scene there were error messages...why? Do you have a newer version of kray? Cause I have the 2.0 one...

[mathewlp_forum]

FUUUUUUUUUUUUUUUUUUUUUU......................KKKKKKKKKKKKKK (sorry )

But you can't imagine how happy I am, I get FINALLY great results for my renders!!!!!!!!!!!!!!!!!!!!!!!!!!
I was working on it since monthes!!!!!

really a big thanks to you johny my friend!!

please look to first pre-final render! (still missing some area (example wood tablets...) but I don't care I'm so in a hurry to show you !!!)


whhaaaaaoooooo so happy

ps: look render time for this HD resolution , hehhehe!!!

This errors are standart becouase I have InternalBeta (but without BIG changes in render) ... don`t worry abount this.
btw. If You know any Shader, setup, command in Kray You can made much better quality then V-ray in 3-8 times faster render.... of coarse You must have Great Ideas.

btw time render (14 min) this is normal for me and ofcoarse I can faster .

[Janusz Biela]

btw last big trick:

Kray is very physics render (sometimes I thing This is Maxwell but 20 times faster...) Don`t use fakes (specular, pixel filter, strange setup : lumi on wals, reflection over 100% blurr over 100%, double glass surfaces, strange NODEs, etc -----> just basic setup and maximumum 80-85% diffuse without reflection, with reflection You must decrese diffuse) If in real world something have 60% diffuse and 5% reflection diffuse try it in Kray.

Ok final render
