is it Possible to use more than Five Material Functions (Base,R,G,B,Alpha) in a Layered Material?
you can extract a very large amount of masks from rgb textures. you could - for example - compare the channels of your mask texture with the channels of a sample color and make a mask from that.
there are most likely more ways to go about that with less instructions and nicer masks, but that’s just what came to my head :X
// i changed the threshold for the equal in the if nodes to get a wider range.
Awesome Thank you!!! I`m new to all of this node thing and cant be this creative with it. But if i got you right, this is a filter which extracts the blue color from the texture.
