Hey Folks,
I would like to ask the funs of the materials, please start the discourse about the Corona's materials setup.
If you have a really good material setup, or you have a question or observing please don't hasitate, just share with the forum.
I think I'm not alone, who really like the materials and shades.
And maybe this is a good starting point to make the Corona's Material Library. I beleive for the great viz you must to knows everything about the materials, shades, colors, and I think one of the most important...about the reflections!
Firts off al I'd like to share a good site, where you will find a good monography about the real materials.
This is the next:

I really greatful for Neil Blevins for him site.
Cheers!
Anybody?

Sure :- ).
Lately, there seems to be a lot of interest in custom BRDF models, esp. one called GGX. Currently only as plugin shader for Vray, Vlado kind of promised they are looking into integrating it.
Seems to both make metal reflection behaviour realistic, but simplify the workflow of what currently constinutes blended layers when attempting metal reflections. Pretty interesting I would say.

Here is the first shared material.
I tried to make water droplets now. I'll see how it's working...

Well,
nice site and intresting stuffs. For me looks like the ggx already in the Corona. In the raw render has a much more reflections for my eyes than VRay. For me was the problem with a VRay, all the time I seen...that's "just" CG. Not really correct reflections.
Opposite this in the Corona, the materials and shaders look like more reflected...more full on life. And I feel space on the pictures, but it's depand of PP.
Maybe two sliders should be good in Corona's Specular highlights options, which one able to changeing the setup between the Pong to Cook-Torrance. I mean on for the color's shader and another one for the blurry...Or is it not working like this ? :)
And how's about the Abbey in Corona ? That's an really good option, because that's make absolutelly real glasses and crystals...

Would it be possible to control glossiness using a graph? It would look more or less like this:
-
it is unfortunately not as easy as plotting a graph. But different BRDFs are possible.

It's sound good and rewarding... ;)

Hi,
I tried something, and I would like to share with the forum for put to the vote.
I made two leather renders in Corona, and there has only one difference between those.
One made with a normal gray bitmap in the reflection channel and another with center color of diffuse map. Other channels and setups still same....
Here is the resaults...what do you think, which one is the realistic reflection? :O
Thank you and let's gives your opinion...
-
IMHO the first one look more natural
-
+1 for the first image
-
...and here I made a "corrected" gray reflection with changed the level and glossines...:)
-
I vote for the first one GREY Reflections

Hi mates,
Here I would like to share my material library for my Nyári konyha scene.
I made in Corona V5, so this is not advanced setups, just basics. Originally I made in VRay with much advanced setups.
I hope it's help for somebody else...
Any comments and observing are welcome.
Cheers!

Hi,
I wanted to share some good and important infos for the correct texturing...
Maybe this is new info for the fellows, maybe not, but I want to say: Thanks Mr. Austris ! :)

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 :]

pretty cool

Hello,
I got this product. Do you have any good instructions or idea for the liquids ?
Thank you very much! :)

Thanks I need to start working on liquids in glasses.

Hi Alex,
How's goin' the liquids in glasses?
If you have any resault, cpuld you share with me?
Or do you waitn' for the A6?
-
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,
Thanx, I will try your setup for my orange juice test. Now I try to get something looks real orange in the glass, but always gonna to fake...There is no real color and no "weight" in the color...
-
put a fall off map in the refraction. try this or invert it.

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.

Fail

Fail
:D
A6 detto...

Hi,
Last night I'd played a bit whit an complex old brass material...
What do you think ? Any advice ?
Cheers !
