I tried orienting billboards for bullet class projectiles a while back and couldn't make anything work, but then again I barely know what I'm doing and OGRE documentation isn't exactly plentiful. It seems the only billboard that works is the hardcoded bullet trail effect. So if pasik is reading this we need either:
1. Access to the bullet trail stuff so we can make additional variants.
2. Orientation for the bullet projectile, like the grenade projectiles already have.
or 3. Grenade class damage that can consume vests in the same way bullets do (for the health point method).
Any one of those should let us make laser guns that aren't goofy or broken in some way.
