I startet using AE for really simple animations a couple of weeks ago and rigth now I`m having the following problem... I am trying to make a flow of smoke with the Particle World and everything looks fine but when I render it the smoke is moving way too fast. I tryed to decrease the velocity but this didn`t change the speed at all. Actualy by decreasing the velocity the only thing that changed was the form of the flow and now it doesn`t even looks good.
So that`s my problem I will be really happy if somebody helps me.
The easiest way to change the speed of the particles is by right click the particle layer > Time > Time Stretch > Increase the Stretch Factor percentage to your desired speed. Then RAM Preview a couple of frames to see if you got your desire speed.
