I think I've found it.
If you go to character>race
you can click on an existing race, bringing up a load of tabs for their colors and parts. if you go to "tinting" you can add new types of warpaint.
Thank you, and yeah, I discovered that myself, but when I add any new war paints, they are always stretched across the face in weird banding effects. The editor also screams at me about the wrong size dds files. It says it wants 256x256, and even though I've sized my dds files to 256x256, I'm still getting that warning.
I finally gave up. If you manage to actually get any new war paints into the game, please share here your process and if you encountered the same problem as I did.
