To get a good uv map is sometimes harder then to model the obj file.

I used uvmapper free when I was modeling in anim8or.
Now I model and uvmap in Hexagon.

Both require lots of planning before making the first polygon.

Sometimes I start the other way around.
First decide what goes in the modeling and what will go into the displacement map.
Then making a rough picture of how I would like the texturing to be.

Think beforehand what parts will shrink or strech when bending.

Only then start the actual modeling.
