Does anyone know how to create a color variation mask like the ones you can find in UDK for their moss and plant masks? We used RGB masks on one of our projects, but they were to mask out specific parts of objects. The ones I am finding in UDK are more noise based. I'm sure I could create noise in Photoshop and just start…
all you have to do is feed a greyscale mask into the alpha of a lerp, and have one lerp input be your texture multiplied by the image or constant 3 you want to use for colour variation and the other input be your plain image. here is a quick example in one of my materials where im using a mask to colorize the brick grout.…
ah i know what you want this is what i did with my vertex paint mask. i plugged this into the alpha of the lerp for all the textures i wanted vertex painted, the what it does it make the grout with some clouds variation fill in first by the vertex paint followed by everything else. I can set the intensity low on the mesh…
Thanks a lot for taking the time to post your shading networks and for explaining what you are doing! I have used something similar to what you describe here at work (although I only had to setup the textures, so it's helpful to see how your creating the shading network). What I am actually asking is how they made the…
