Mirror a mesh - problems with textures

Hi ive got a problem. I mirror a mesh in the Z axis, textures show on the right side until I click play, then the textures flip to the otherside?!? If it shows fine normally why does it change when running your blender game??? I mean I can flip the textures then they will flip the right way when playing the game, or have a texture both sides, thats fine its just I would prefer everything to look the same when you are editing/playing your game. Thanks

Duplicate the object go into edit mode, then select all the vertices and mirror it on the corresponding global axis and tada looks the same in 3d vieaw as in gamemode :smiley:

Thanks!!! Got it working, looks gr8!
