texture uv, i think what the guy in the quote means is that you need to aquire a UV Snapshot of the UV points for the texture painting.

I've only ever done this with a poly mesh, what you do is open a split panel (Prespective/ UV Editor) then select the mesh.

Edit Polygons -> Texture -> Automatic Mapping -> Options

Set details of the type of texture you will be using- e.g. set based on whether your textures will be high res or low res.

In UV Texture editor, go to Polygons (POLYGONS IN TEXTURE EDITOR) then to UV Snapshot. set it up to the specifications you want then hit OK.

Import to Photoshop and then paint it.
