Hi elmaster200. It's a custom model, using a custom texture. The custom textures are Lightning1bRed.blp, Lightning2bRed.blp and Lightning4bRed.blp (and possibly LightningBallRed). They also need the right custom path specified in the import screen (just 'Lightning1bRed.blp', 'Lightning2bRed.blp', 'Lightning4bRed.blp' and 'LightningBallRed' respectively - same as in the import screen).
By the way, if you're going to be using resources from my campaign in your maps, please give me credit for them.
