By the way, the plasma cannon metal shader isn't all that appropriate. Change the bitmaps in the powerups/flamethrower ammo to fp/plasma cannon/metal if you want better results (and then swap the shader with that one).
***Please be aware that the plasma cannon model metas are unstable- keep backups of your mod before EVER inserting a plasma cannon model of ANY kind. Don't worry, if you didn't, then read this tutorial.
