GGX - best way to recreate it for all metals, problems translating to Corona

Corona Corona for 3ds Max General

It’s cool once you start getting creative with it, such as darkening the falloff and adding into AO and adding dirt layers, I had a quick go now and attached setup :smiley:

Wow that tarnished gold material is really good! Would you mind uploading the material here for us to test?

23

You deserve many beers Gestalt !

24

I’m waiting for that baby, really nice effort & examples !

25

GGX Yes… was just coincidentally also watching grant’s advanced shader tutorial today and was about to start experimenting to see how i can recreate it in corona then i find you Gestalt.

WELL DONE

26

I´ve tried to reproduce Grants materials with Corona, and I think it works really well but GGX would be great to have!!

27

do you mind sharing some renders of them Daniel

28

Sure, I will do that as soon as I get home!

Keymaster - Very exciting news, sure something amazing will come of it!
Juraj - Beer is always good, glad to be of service :smiley:

I have just uploaded the base gold material to play with on CML, thought that was the easiest option.
I will upload the Tarnished Gold when I find time to make a custom map as yesterday I just banged in the first dirt map available and it may not be freely distributable, just want to be sure.

Have to flag up Grant’s course, it really is that bloody good, totally recommend signing up and completely transferable to Corona.
Bit like Corona in it’s intelligent, no nonsense, “if you’re gonna do it, do it properly” style!

Tarnished Gold uploaded to CML.

31

can not find iton CML …can to provided the link please???

32

Sorry, yep you will have to wait for CML to administer them.

Here is a render of my attempt at copper, not 100% satisfied with the result.

I hope it is ok that I used Grants shaderball hehe..

The reference images showed several types of copper, some more pink and some more orange. So I went for a more orange type.

Nice :- )

I kept his ball too btw, no reason to change it. It’s the nicest ball I’ve seen to date so why even bother.
Seems like great HDRi you used there, mind say what is it ?

35

Ok

36

(not 100% satisfied with the result) That’s why i jut REQUESTED for direct implementation of GGX in corona
and also as juraj said many gaming programs are implementing PBR/PBS (Physically Based Rendering/Shading) why Not we can expect ggx in CORONA :confused:
as we all know how well corona is made …believe me i am using it since one year not even one crash till TODAY…
HOWEVER …IT WILL TAKE SOME TIME …Ondra Karlík can Do it

37

Thanks! :smiley: Yes his shaderball is great! Sure, I used “Chelsea Stairs” from hdrlabs.com, tried a few and found that it gave a pretty good result.

I was asked to upload a render with a material created the way Grant explains in his tutorials, it was not my intention to say that the request was not useful or anything.
I agree that GGX would be great to have implemented in Corona.

38

Thanks Daniel, I totally forget about HDRLabs existence. The way the one you chose shows the highlights completely rocks.

39

The materials being produced in this thread are amazing. That’s probably the most realistic CG copper material I’ve ever seen!

do you mind also posting the shading network for this material, really amazing
