Ok I am bored this scene. Time 18 min.

Fantastic time, fantastic output! All we need now is johny quick 'render settings brain dump' so we can fully understand how you do do this

Hi, how can you get this such white-blue color of the walls?
what amounts for:
luminosity? diffuse? reflection blur?
Gamma, exposure? tone map exponential?
what color exactly? 255,255,255???

YES PLEASE!!!! TELL US MORE ABOUT YOUR RENDER SETTINGS cause everytime I see your posts and great renders but never lots of details about how...!


2ND QUESTION:

vsele wrote:Hi Johnny....how did you get the scene into LW? I've tried with the latest FBX Plugin from autodesk for Max 2008 but I can't get the texture loaded along with the model in LW......what am I doing wrong?

Procedure:
1/export object from 3Dmax to obj.
2/If You have max 2008 please select export to obj. file, if You have max 2009 please select export with Lightwave setup obj. (avilable in new max exporter menu)
3/if You had max2008 please use Accutrans tool http://www.micromouse.ca/ , open obj. file and save as lwo file, if You have max2009 You can open obj file stright in Modeler - but I thing much better is when You open always it under Accutrans.
4/rescale under Modelere whole obj. to 2.54%.
5/You save all oryginall UVmaps from max, but sometimes avilable is only one UVmaps for all surfaces (but this is no problem).

How can I save uvmaps from max??

Thanks for help!

If You need white walls You must put desaturate Shader on the floor (same trick in V-ray).
But please don`t use strong setup (close 100%) becouse tottaly You kill colours in render and after that You receive white colours (render must have warm filling...) 40-60% is OK.
Diffuse write again: max cunt is 80-85% (exap: floor diffuse 75% , reflection 10%)
I use Sunsky+Sun (only for small light and reflections + Area (blue colors) in windows with Power Shader. Exponential 1.4-1.6 , 20 bounce light.
But this is very important: good setup textures and good idea for position light.

Just export scene to obj format. Sometimes I received bad UVmaps but this is very rarely.


Desaturate shader:

Thank you very much for these precious informations!!

One last thing, when you say 20 bounce light, do you mean Kray header command recurse=20 or Lightwave native Ray recusion limit to 20??? OR totally something else lol ????

Thanksssssssss again!

recurse 20;

... but You can 1000 (I thing this is maximum for Kray engine)

very nice comparison. the vray version has a wierd dark shadow under the seat. looks unnatural.

when i try to use exponential parameter 1.4up the colors become desaturated, washed out and there's loss of detail. 20 bounce light doesn't that make the light stronger and you lose shadows, etc?

I thing good way is in PowerShader in Area light (maximum 3) Power for Sun (maximum 5)
Exponential over 2.0 and Power in Kray setup under 1.0 (0.5 to 0.7) with recurse 20

I didn't get this. Exponential exposure or paramater? what's power in kray under 1.0?

This scene done by you and phedian I assume didn't use power shader but still have very good white like the room is filled with lights but i'm sure there's few lights in there. not overexposed or overbright, too.

Exponential around (2 - 2.4) Parametr always 1.0.
Power in Kray is in PHOTONS TAB. This tool make contrast (smaller - bigger contrast, deeper shadows, closer raytracing render)

Thanks johny. Now I get it.
