I have a Particular light streak (giving off streaks & spheres) that I would like to have enter the screen, then forward motion & particles slow to a freeze, and then have the particles drop & bounce to the floor. Been looking for a workflow & have been working on a solution. Anyone know of a tutorial? Thanks.
Animate the move of your Emitter at a constant speed. Precomp - enable Time Remap and adjust timing to get the desired effect. You will need to tweak the gravity and particle birthrate and speed to get the effect you're after.
