@ Julian & Leonard, Thank you guys. I will check your scenes and explanations when I get home later.
@Ciaran, It does, but only so for the particles with strands. Particles without strands get filtered out of the logic. So even though I can work out the orientation I need from the location StrandPosition's, when I set self.Orientation, it only sets it for the strandy particles, not the others. That's my main problem. How do I force my set on self.Orientation to be on the original particle IDs?
