Well, I think I tried that. I’ll describe what I did first:
I created a null and a light, renaming the light Motion Path 2
I plotted out the points on the null, then pickwhipped the position of Motion Path 2 to the position of the Light. The particles didn’t follow the path =\
I don’t think that Particular recognizes that it’s parented to other keyframes.
Is this what you were describing?
