I was thinking about UV mapper Pro, but now all I think I need is some UV texturing tutorials for Blender. Playing around with texture painting in blender made me realize, there is a whole world here I need to learn.
 I was hoping that I chould get away with just learning 3-D texture painting, but had noticed it don't have a clone tool. I need that to do photorealistic textures.
Thank you for your prompt responses.

PS.  Is there any good tutorials for UV texturing in blender?
