This is my version of car paint material.
Tried to find simple way to do it. Only two layers used here.

Base layer gives colour and flakes.
Second layer is for varnish only.

What do you think about it?

...and as you see, it's not a car.

Thanks!

Very nice - and pointy

[chrisvconley]

Very cool! I think people are starting to get the hang of the Maxwell material system and explore its possibilities.

Constructive crit: Not sure how you are trying to do it, but the finish is missing the sparkle of the metal flake in the paint. This looks a bit more like a evenly distributed blotchy rash.

I wish I had a suggestion for getting the flakes to sparkle, but you're ahead of me!!!

Thanks for sharing!

chrisvconley: "evenly distributed blotchy rash?"
That what it is. I don't have good texture for flakes, but
i was just trying to make this basic material. Now i should
find better texture and add sparkles somehow?

Thanks for your crit!

Well there's no way you can acheive a 100% real glitter with the maxwell material only. It's not in the reflectivity parameter but in angle of the light that gets reflected from the grains in the glitter/sparkle material.

hybaj,

whaddya mean "There's no way..." ?!!!

That's not the spirit!

Let's see what we can come up with...

[sandykoufax]

Cool material!!

something like a pearl.

[Hybaj]

Well i was looking for a way to do it with the material only but it just seems impossible to make it pyshicaly correct. But hmm you're right it's not the spirit. I just woke up and i think i also just came up with a quite physicaly correct way to do it

[Jozvex]

Bump mapping for just the flake layer perhaps?

Your quote is true as long as long as Normal mapping is broken.
As soon as this is fixed, it is indeed very possible.

Yeah normal mapping is probably one of the ingredients but hmm it's going to be much harder than that.. probably

[3dtrialpractice]

normal mapping for flakes?!? why? why even bump map it.. are flakes really raised up and such? huh I would figure just a seprate layer to control their reflection....

LarsSon.. I think this is the BEST flake shader done so far.. as far as showing off great big nice "bling bling" flakes.. maybe too excessive for most car paints but if ya wanna go for a Big flake look this one is great..

care to share your techniqe?
