First attemt for texturing, forgot to hide the UV Snapshot layer in photoshop when exporting so you can still see the lines.
This is the tutorial I used to teach myself UV mapping.
After laying out the UVs I use the PSD Network in Maya to export the UV Map to Photoshop. In Maya you can create a PSD Network (UV Texture Editor -> Create PSD Network). This let you create a photoshop file directly from within Maya. And with a single click you can make every update in photoshop immediatly visible in Maya.
