Interior UV Coordinates

An interior uv is a uv map specifically for use with a vehicle's windows. Interior UVs map an interior texture to the window areas and add perspective and depth to the interior. Interior UV coordinates are similar to standard UV coordinates, the only difference being the window maps.
