I need a way to mask by color ID (splatmap) from one texture. I have 8 colors (red, green, blue, cyan, magenta, yellow, black, white). I need to perform a mask based on these colors… same way as software SUBSTANCE PAINTER makes with color ID.

For the moment I tried with a Cop2Net (composite network with chromakey, colorcorrect, levels, etc) with no luck.

¿¿Any ideas on how to only mask an specific color??

Thanks in advance.
