nice! Try flipping the normals of the cone. if you have a camera normal shader (I reccomend getting these in your engine if you have a code monkey handy) you can make a falloff to remove that sharp edge. As the polys turn away from the camera they fade out. I make my muzzle flash textures really subtle and use more planes.…
Doesn't autosprite2 align itself along the vertical axis and then rotate the plane towards the camera? AKA billboard? EDIT: Your Daveness, Cheapy is his own code monkey.
