Run this script from "File->Export" menu. A pop-up will ask whether you

Known issues:<br>
Doesn't handle multiple materials (don't use material indices);<br>
Doesn't handle multiple UV textures on a single mesh (create a mesh for each texture);<br>
Can't get the texture array associated with material * not the UV ones;
