Applying IPO Time to particles

Is there any way to apply a time ipo…or that type of effect to particles?

Fixed it…didn’t realize I had to use the Objects Time IPO.

Be aware that the IPO curve for particles is relative to the particle´s life. So, if you curve starts at frame 1, the effect will occur every time a particle has 1 frame of life. If you set have a keyframe at frame 246, the effect won´t occur exactly at frame 246, but 246 frames after the particle is born.

I’ve noticed that…and can’t seem to get the effect I’m looking for…oh well…more experimenting.
