You can import pre-made uv templates easily. (I.e. use the standard Posette, Vicki, etc. templates.) Deep Paint 3D is wonderful for making complicated textures. I'm saving up my pennies to get it. I don't see a reason to get Texture Weapons as I have UVMapper Pro, though even UVMapper basic would take care of the need for Texture Weapons, from what I've seen.
