Basic question-What is the advantage of doing layered material? What is the maxiumum layered materials and sublayers one could do? Is layered material like 2 or more images/colors mixed together to make one?
As I understand it to this point each layer has unique properties that work together to provide a certain material look, no?

Hello Patricks, I understand the busy part. Thanks for that explanation.
Yes, you have been most helpful.
I have been reading the material info. It's starting to sink in. It's one of those things you just have to do several times until it sinks in.
I have to go now, it's my birthday. I sometimes go away for periods and not able to keep up with the board daily. I apologize for my late answer.

Thanks for all you support,

lapx

Hi and first of all thank you for making the guide.

I'm used to create shaders or material the "old way" (scan line render) so all these physics and optical rules are new to me. Among that my physics knowledge is poor (well, let's say average...).

I did understand quiet well the 2 main rules you explain (Energy Conservation and Fresnel Reflection) and the advantage of using Procedural Fresnel for dealing with both rules at the same time (after reading and testing showed materials at least 2 times...).
But still there are some explanations that I did not understand well enough to be able to use them.

Example 1 - Page 13th of the guide :
"Now that we have created our basic plastic material, adjusting it for our needs is very easy because we only have to give it the appropriate diffuse color and adjust the shininess value to make the reflection more blurry or more crisp,...".
Should I adjust the shininess value (according settings showed on page 16) on the Matte/Phong Diffuse color layer or on the Matte/Phong Reflection layer ? Or should I create a 3rd layer for that ?
I have tried these 3 solutions but was not able to reproduce similar results as on page 16 (Specular Shininess).

Example 2 - Green glass on page 22 and 26 :
Don't seem to be done the same way according to the explanation but give same result (apparently). First (page 22) seems to use Dielectric Glass (according to the title) while the other (page 26) seems to use 2 Matte/Phong layers. Have tried both but was unable to get the same nice green glass that you got. Kind of, but not the same...

I think these kind of things (these are just 2 examples among others) could be best described.

Patricks, be sure that this is not to criticize the good job you've done with that guide ! It's just that I think it might even get better...
(I might even translate it in French one of these days when I will be sure to understand well enough all the physics concept behind).

Thanks for all and very best regards.

Example 1 : in the Matte/Phong Reflection channel. ( ~10 is very blurry, 10 000 is perfect reflection)

Example 2 : re-reading tutorial...wait...

Thank you both Alex & Patricks for fast reply.

Unfortunately I won't be able of KTing today...

But I will re-read and re-work these points of the Guide as soon as possible (Monday I guess) because I can feel that one has to clearly understand and master the Material Editor in order to take full advantage of KT.

Best regards.

Hello !

I hope I am in the right topic.

you will help me if somebody was able to explain to me how create material from zero and how create material library from nothing.
I read the guide but i don't find somethink about.
thank you for your answers.
