Anybody have an idea on how to implement "laser-blast" effects? Specifically that semi-transparant neon glow. My guess: model the core of the laser as a 3d rectangle, then use semi-transparent rectangles around it to create the glow. Will this work? cheers

Or just use a sprite which always rotates around one axis to face the camera

By "sprite" I take it you mean a texture-mapped quad? Good idea.

Similarily, I was thinking of making 4 blended quads in an "+" pattern around the laser core. Then I wouldn''t have to the rotation.

Thanks!
