Re: Trying to make this Oxidized type Brass material
Here's my result.

AO doesnt work as expected. When you have dirt on a small number it looks ok, but, when you increase it, it spreads over the whole coin very subttle....

I want it to be small but really intense...., but cannot get it like that...

cheers

thanks, but no much more intense. Attached what i have (I made it pink to show) - The intensity must be super strong, but not spreading over the whole coin.

No combination of Color Spread and Ray Directionality in my sample file will get you where you want to be?

Wow ok.....you did it totally different than me...makes a huge difference!?

Why are you using it as a layer mask?

Thank you....

Attached my updated render. (Unsure why it works this way using a layer mask, but so glad it does!)

Re: Trying to make this Oxidized type Brass material
Nice to hear it works for you. It is one of the cases where material tweaking without the IR would be a major PITA ;)

A layer mask lets you choose the base and the dirt color better.
In the end, you can also use this method to e. g. use different IORs (brass and patina) or more.
