Jim, I can see where doing a rotating lawn sprinkler would be difficult. Perhaps I misunderstood what the problem is. As I picture it your sprinkler will consist of 2 particle sources. They will rotate around a pivot point half way between them and will both face away from the pivot point toward the outside of the circle. You need to make a keyframe describing the position and heading of each particle source for each frame of the anim. Sparks will then generate the particle streams based on these keyframes. Is this pretty much what you're trying to do? If so, why don't you e-mail me a scene file you've done by hand. (About 30 frames will do.) A long time ago I wrote a program to generate paths for VistaPro that had some simple motions built in. It may be possible for me to modify it to write LightWave scenes. If it looks like a lot of work perhaps I'll upload the source code. It's written in Cando but it will easily translate to basic (that's what I designed it in) and should be simple enough to convert to ARexx. Jeff H…
