How to Make Your AI Unique
written by Springheel
Running into clones of the same AI over and over again can damage a player's suspension of disbelief. Beyond that, it's just plain boring. Luckily, there are some fairly easy ways to make your AI look a little different from each other.
Skins
An easy--and quite effective--way to make your AI quite different from each other is to use an alternate skin. A skin is basically a different texture from the default. It could be as simple as changing the colour of an AI's tunic from blue to green, or a totally new texture that changes the clothing entirely (though obviously the basic shape of the model remains the same).
At the moment, not very many of The Dark Mod's AI actually have alternate skins to choose from, but things will improve slowly.
To use a different skin, you need to add the key/var "skin" "[skin name]" to the AI in the entity window. You can browse for skins in D3ed, but existing skins will not show up in the "Matching Model" section, so you would have to scroll through the existing skins to find them (they should be under "characters") (look this up). I don't know how this works in Dark Radiant.
Attaching Different Head
Another option is choosing a different head.
