To make this work properly, I'm going to clone some layers and flatten them and then do some copying and pasting between channels. Right now in my overall container map, I have my specularity groups on and my diffused groups for rust and base blue and green are hidden. I'm going to hold Ctrl while I pick a Rust spec and Spec base, that way I select both. I'll hold Alt and drag them down as copies. I'll turn off the originals and press Ctrl+E, flattening down both of those groups into one image. I want to make sure the order is right before I flatten. Now I'll take those and select them by pressing Ctrl+A, Ctrl+C for copy and I'll go over to the Channels palette. Right now all I have is a Red, Green, and a Blue channel; there is no Alpha, no…
