If rotating the arm and projection paint again, there will be a overlapping seam, particularly like this one as the texture are in rectangular shape, I think DP3D with TW is suitable for fractal type, or skin type as these textures have no visible seam when painting in overlapping area after rorate to next angle. it is all about UVMap, TW is cool to create good UVMap, but I still like to use UVMapper by Steve before importing into DP3D.
