I am trying to recreate some metal with black paint, but cannot seem to get it working.
How ever i try, i still get a brushed metal with "grey" paint.
I two layers, one is the brushed metal, the other is a pure black material, with reflectance at 1,1,1, and ref 90 at 4,4,4
roughness is 99. I am using a weight map to blend the two.
no matter what i try, i still get a silver sphere with a mid grey paint.
if anyone can help i would be greatful, thanks.

I'm not quite sure what exactly you're after.
Is it something like this:

Or this:

Or just something black and shiny???
Would be nice if you post some reference photos to make it clear.

THanks for the reply
Here is a ref that illustrates what i am trying to achieve.

as you can see, there is Black paint on the metal detailing the logo, numbers etc.
I would like to know how you can achieve this. As i said, when i use a layer for the metal,
then a layer for the black paint, and use a wieght map in the black paint layer. the black still comes out greyish.

You have to use the weightmap for BOTH layers, inverted in one of the layers.
Then you can adjust the layers as two independant materials.

kurt,
that did it. Perfect.. not sure why i did not think of that...
I need to really sit down and learn this stuff.
Question, does anyone know if Mr. Verta has released the 3 installment of his mat training vids?
watched the first two, but cannot see to see the third set anywhere...

Ehh...sorry guys :oops: , I was actually talking about weightmaps, just called them clipmaps - you sort of use a clipmap for metal and an opposite clipmap for paint, so there's the point.
But in fact you CAN go with pure clipmaps if you'd like to: double geometry + 2 single-layer MXM's: one with a metal clipmap, the other with the paint clipmap :mrgreen:
