The idea goes like this. having the possibility of having units that cycle through a series of skins (.tga files) as they are produced. Basically this means that artists can make variations very easilly (changing the tone, details, etc) to give the game more realism and personality without too much effort or strain to get this variation.
This means we could produce horsemen with horses of diffent colors, one blacksmith could have a mustache, and the next one that is produced has none, but has black hair instead. Dragons could come in various colors (I can make color variations in 2 seconds in gimp, I've tested this out on a couple of occasions.
So this means no extra modeling, just tweaking of the skins (.tga files) and some code to cycle as units are produced.
Hopefully this could be programmed in a way that the game autodetects multiple skins (ie the filename + numbers 1-n or 0-n) or in a way that this info could be included in xml files.
I hope this doesn't require too much programming, because I think it would be cool, in that it would add a lot of variation in the game very quickly. At least I know I'd be productive in that area.
I'm curious to hear what you all think.
