I have just read Krusty's basic instructions, looks like they were written for AH2. In it he says to download the hi-res pack, there doesn't seem to be one for AH3 so I assume there really isn't one.
I have been trying the layering process, I can create the layer, reduce its opacity so I can see the base layer. My question now is, do you zoom in to see the lines, if so how do you deal with the pixels? I think I get how to make the panel and rivet layers, do I need to mask them at this point?
