Right okay, and if I want to use an existing standard combat icon for someone else so that they can be both an npc and a monster there's no way to point to the right icon so I have to make a copy it then.
So how do I extract the icon I need? I'm not at home right now but I had a look through the folders before and couldn't see the combat icon pic files, maybe I missed them.
I usually use Dan Autery's wonderful SHOW
program (although these days I have to run it through DosBox because of incompatibility with Windows eight). It allows you to scan most sorts of art files, including *.tlbs, and make a copy, if you want, in pcx format.
If there's a piece of default art that I want a quick pcx of, say a monster combat icon, I would use SHOW to go to UA's Disk 2 (or Default.dsn, if I had UAShell installed), and click on Cpic.tlb (which holds all the default Monster and NPC combat icons). I would scan to the one I wanted and then use the command to make a copy (which creates a pcx file that I could then put into UA's Art folder and then Import it through UA's internal editor over the combat icon I wanted replaced).
If I saw a cool combat icon in somebody else's mod that I was playing, I could use SHOW to scan (slideshow) the Cpic tlb files in their design folder (*.dsn) until I found the one I wanted and make a copy.
I also use SHOW to quickly scan art packs that have been Uploaded to the UA File Archive. It is an invaluable tool for FRUArtists. (Thank you, Dan Autery!)
