The material has masks for dirt and paint, with a wood base that can be tweaked as well. The default configuration is a pale wood color with red paint and dirt on top. Base values like color and roughness have been setup in a way that's easy to tweak without comprising the default masks.

This product includes the smart material and a quick overview guide to understand how to best use it. The example used in the quick overview guide uses a previous Smart Material I made, which you can find in my store. https://flippednormals.com/downloads/smart-material-worn-painted-metal/
