I was wondering how to turn off image tiling for textures in the game engine. My UV map would make it tile right now (i.e. it's bigger than the map), but I can't figure out how to turn tiling off. I'm using the game engine with GLSL enabled.
In the UV Image Editor, bring up the properties toolshelf with N and under Game Properties, under the Clamp group, tick X and Y, you can now scale your map larger than your image without tiling your texture..
