I decreased mine to 7%.įinally, since we are dealing with a forceful explosion, remember to enable the motion blur switch on the layer as well as on the composition. You can keep them all more evenly spread out by lowering the Velocity Random property under the Emitter tab. This is often caused by the Velocity Random property being too high, causing the particles to travel different distances from their point of emission. I felt the final distribution of the particles was a little bit too random. Playing this effect back you will now have white particles shooting out of the emitter and slowing down to form something that looks like fireworks. Increase your air resistance until all of your particles stay within an area that is more realistic for a fireworks effect. You will find this property under the Physics –> Air tab. In Trapcode Particular we can simulate this physics behaviour by increasing the Air Resistance property. They are being slowed down by friction with the air. If you watch real life fireworks going off you, will see that the sparks that shoot out of the explosions tend to slow down quickly and then slowly sink downwards. However, due to their velocity they now travel much too far and end up being all spread out over the screen. The particles are now emitted with a lot of more force.

You can do this by increasing the Velocity property in the Emitter tab for the Particular effect. Next we need to amp up the velocity of the particles since a real fireworks explosion has a lot more power and speed. If you now play back the effect, you should see a burst of white particles being emitted. This will cause Particular to emit 6000 particles per second for a single frame only. To do this, expand the Emitter tab of the Particular effect and keyframe the Particles/sec property.Īdd 3 keyframes to animate this property to go from 0 to some large number (I used 6000) and then back to 0. Instead of a continuous stream of particles, we want a powerful short burst at the time of our fireworks explosion. The first thing we need to change is the way the particles are being emitted.
