Building the Firework Head in Unreal Editor for Fortnite

Begin the firework by building the firework head. This emitter drives the other emitters and sends event information to them through an event, signaling them to work at specific times during the effect phase.

1. Click Properties on the empty emitter and the Details panel will display the properties for the empty emitter.

2. Enable Required Persistent IDs. In this example, Required IDs help other emitters to reliably reference this emitter's particles.

   

Emitter Update

Emitter Update modules occur every time the emitter ticks on the CPU. Modules in this group should compute values for Particle Spawn or Update parameters in this frame. Modules are executed in order, from the top to the bottom of the stack.

These settings determine the number of effects spawned and how many times the effects spawn.

1. Select the Emitter Update group to open the Emitter Update module settings in the Details panel.
2. Click the Plus icon next to Emitter Update and select Spawn Burst Instantaneous from the dropdown menu. The Spawn Burst Instantaneous settings automatically open in the Details panel.
3. Ensure the Spawn Count setting is set to 1. This causes the emitter to spawn one particle at a time.
