textures in Gile[s] or Tattoo

Hi, I'm looking for a tool to help paint textures on compound surfaces, like small boats. After looking at Tattoo and Gile[s] it seems that I could adequately paint textures in Gile[s] and get the great lightmapping features.

Does someone have recommendations for texturing complex models? I'm not wild about painting directly on the unwrapped 2D textures...


thanks-
Paul
