Okay, so I took a look into this and I've been able to get it to show a single image, just by replacing "CivilzationVAtlas.dds" with whatever the filename is of the dds you want to use - only works with ingame images though. What I need to try and figure out now, though, is how to point to something which shares a filename - if I point to "CivilzationVAtlas.dds" it shows me the one for the relevant expansion, in this case the factories for BNW. If I want to point to Atlas from Vanilla though, I can't, because the filename is the same as the BNW one. Any idea how to point to Vanilla's one?
