I recently begun to research about this and tryed to get a real nice looking metallic effect and think im getting there!. The good thing about this mat is that it lets u mix more then 10 layers at the same time!
So for a real car paint u have a verry blurry base layer, normaly light grey or white! then the base coat were the color is, then ontop of that the metallic and then the clearcoat.
So if there is anyone that has any exp in this one! can post ur shader renders to share with other and with settings!
Here is the silver paint that im working on! Since last update i added a paintbump in the clearcoat layer to give it a little ripple in paint as in real world. Add a xyz_uvmap on every bodypart to show it corect and u might have to change the tiling to match your area.
I want the ones that are trying this paint out or want to take it further, Show some progress in THIS thread. That way wee keep it in the same place and will help the new ppl to find it too.

ps... AND PLEASE!!! Credit me in forum post for the paint.. Thats the least u can do for me ...
well the last production showcase here on the board was done with vrayblend materials mostly :
But as you will hopefully understand i wont be posting our settings heh. Am willing to post tips if you run into any problems.

Hi there Instinct.
Ahh ok thas nice to here, U know a god source for som tips or can u make a quick laydown on the basics of the build up of the material! i think i got it but the right parameters are confusing me abit
well your basic outline above was pretty spot on. a basic layer, a colour layer (or metallic with lossie) a clearcoat and eventually a flakes layer. via the mask map slots you can add falloffs to your likings. Mind you that the default mode is not additive but blend (wich is a lot more correct then max's shellac wich is only additive) but at first it's a bit confusing. it's a lot of trial and error to get the experience and understand what parameter affects what (as tweaking one falloff will also affect the other layers of course for example)

Ye, i got some exp in real paints on car and try to think as real as poss and i think im getting somewhat a near result of what i have in mind!
Not a bad start i'd say. could you post screenies of the material settings ? Would make things easier to judge.

Hi and verry thanx for quick reply.
The buildup is pretty simple. Im rendering right now so i dont whant to stop it
But the thing is that this blendmtl only has 2 layers! like a normal shellac, Thats whats bothering me. Is there any need for one more?
It has a base with a gradiant map in diffuse from a spot of grey to almost black. And in the spot of light grey i added a "speckel" to give all the light areas some flakyness. For the reflection its pure white to black and fresnel falloff. As for the reflection gloss its on 1 but controled by another falloff from almost white and other collor slightly darker making a little spill light visible..
Then there is the top coating wich is set to a blend level of 80 to show more of the paint beneth..
okay..for starters it depends what kind of material you are heading for (metallic/clear). Generally i would suggest not to fresnel the VrayMats inside the blends, but instead put the falloff into the Mask slot of the VrayBlend. Also i usually dont falloff the metallic layer. Yours looks rather sharp still in places wich makes it look rather steelish then metallic.
