The unwrapping progress is going well, i am slowly but surely getting there with the main body just a few more polys to unwrap and the body is done then ill move on to the tracks and wheels next. I should have the body done by the end of today if not tomorrow and hopefully have the whole model unwrapped within the next few days so i can start texturing. To help with the unwrapping i have been using the peel, break, weld and reshape tools to get an accurate UV. If the mapping is distorted then i peel the mesh, break certain faces so i can position them correctly and weld them to the corresponding polys, i then reshape the finished uv until the squares are all even on the mesh. sometimes it takes a bit of manual labor, moving the edges and vertices to get the mesh right.
