[dragonmike087]

Hi I trying to make a kiwi map and I am making all my own buildings, bridges etc but Ive run into a issue. Im using blender to make my buildings etc and gimp 2 to add textures. When I put a texture into ge it comes up warning (profomace) error .png texture raw format. Can any one please help and also any good videos on texturing a building in blender and getting it into ge Thanks.
