7. Now we are going to add the UV coordinates for the polygons that make up the inside of the leg to the "player" UV map. Deselect any currently selected polygons and select the surface for the inside of the leg in the statistics panel. Choose "create new UV texture map", then select the existing "player" UV map and create a "planar" type map on the X-axis for the selected surface. Last, move the UV-coordinates out of the active UV area.
How To:
To deselect any existing polygons, Left Click in any empty space in the left menu. Now select the polygons that make up the inside leg surface in the "statistics" panel as we did before. At the bottom right of the screen you will see the map controls: W T M (none). Press the "T" button and from the pop-up menu select "new". In the "Create UV Texture Map" dialog, use the drop-down arrow by name to choose the existing map "player". Set the Map Type to "planar", the Axis to "X" and Settings to "Automatic". Press "ok". To move the UV coordinates press "t" or in the top menu select "Modify" then "Move" in the left menu. Now drag the polygons right in the UV Texture view.
