Alright, let’s assume I have a plane, keyframed to move along the x axis. I also have a particle system setup so the plane leaves a trail of particles. The assigned material is a halo with an ipo set so that the halo’s size and color gradually change over time.
Issue: All the halo’s (the ones assigned to brand new particles and old ones alike) recieve the changes along world time. For example, If I have particle A emitted at frame 1, and particle B emitted at frame 50, and the material set for the size to expand from small to large and from white to black over fifty frames, particle A and B will both be black on frame fifty.
I was wondering if there’s a way to set the particle material to react to the particle’s lifespan. This way particle A will be small and white at first, and become large and black at frame fifty. at the same time, particle b will be emitted, small and white (frame 50) and become large and black in fifty frames (frame 100).
I hope this is clear, I’m at school so I can’t upload an illustration of what I mean.
EDIT:
hopefully this clears it up. ignore the smokieness of “what I want” i meant for it to turn out like the black Halo’s in the second panel. I was just too lazy so I used actions when I made the picture.
