Old Sofa Material

Initially it was a simple exercise that my professor gave me. I continued to work on it until reaching this result.
This material is fully customizable. It's 100% substance designer.
Params:
~Leather/Weave choice
~Leather/Weave color, saturation and luminosity (also avaible on buttons and tiles)
~Dirt level, color and opacity
-Scratches amount and opacity
~Normal, height, roughness and ambient values
You can use this material in Unreal Engine 4 and set this params in real time!

Hope you'll like it!
