Hello,

First of all, I'd like to thank you very much for Juraj the info about the BRDF, because his opened my eye. Thx!

Well I really hate the maths, but I have to dig into the BRDF, because I belief this is one of the most important for the correct reflections in CG. And I seen a lot of really strong and ughly reflections in the Gallery. Mine too, but I want to learn the correct way and this BRDF is interesting...and  I think this is IMPORTANT like the anisotropic reflections for the metals...

If  you disaggred with me...don't hasitate, just share your mind!

Cheers folks!

so, how does Albedo translate it self into making shaders?

If diffuse has a texture, then does the value of the gray scale matter or its percentage? 0.0 to 1.0?

I know blacks have to be above 5,5,5,?
and whites below 220,220,220,

If i really want my blacks to be black, i don't hesitate to turn them down to 2-3. And if this not enough i do lower value. But i respect whites and try not to mess with them :]

Kinda Ok. Here are some Randers. I am attaching the material In a max file. you can change the color of the liquid and all that good stuff.  The top of the glass is broken/rough/spiky, dont cut your lips.

Hi Alex,

before I have tried the refraction with faloff and the result a bit less colored than the color gradient in refraction.

Here is the render with your suggestion and if you should to try, here is the scene for max2014.
Maybe I got something wrong...or I have to try some noised gradient in the refraction or translucency.
I think I have a small misunderstood how's working the refraction and translucency together.

I think without SSS this is the mission impossible... O_O

Ill try it out, but orange juice is like milk, in translucency factor. Corona A5 needs SSS. Without it, its war with the material editor.
