Hello, I have a little bit of a problem with a model. It says the alpha channel of the texture is packed within the blue channel of a 3 channel composite. Meaning there is a colored picture and they placed the opacity map data only in the blue channel. How do I isolate the blue channel in Cinema 4d Materials, to use only the blue channel of the 3 color composite to affect the alpha (opacity map)? Thanks in advance, anyone?
