This may seem ignorant to the source code changes, but is there any way to make the beam PCX's tile? I have made a rather nice rainbow beam using Photodraw and Paint's pixel editing (to create black patches in the beam), but it is all stretched out along the beam length and it looks terrible.
Also, I think I know where that muzzle flash came from. It looks like a certain wall hit in Descent 3. I'll try again to make a nice beam.
