Hi to anyone reading.
Im starting to use cycles, it has been a lot of brain pain atm since i have never used nodes to composite textures.
What im trying to do is something you would do on photoshop pretty easily: combine canvas with different blend modes.
I want to emulate dirt over a wall without using external maps, just procedurals. The process would be like the following on the image, blend the clouds with different blend modes over the default diffuse color ( I have been using the node MIX to do this but i just cant get it to work)
any help will be much appreciated.
