# Fire

The Fire tab allows you to configure the precise timing of pyrotechnic charge activation for each drone. Up to three separate charges can be triggered per drone, and you can define the duration of each trigger. This feature enables accurate synchronization between pyrotechnics and the show choreography.

> ***Note that pyrotechnic effects are not visible in Blender. The tool only schedules the trigger timings; the actual visual effects must be handled externally during the real-life execution of the show.***

The `Fire` panel is used to control the IO Star extension board for fireworks.

The board has 3 channels, to trigger up to 3 fireworks.

`Duration` is the duration of the impulse step to trigger the firework (by default 40 ms).

To trigger a fire:

1. Select the drones to trigger
2. Move to the desired frame
3. Set `Duration`
4. Click on `Fire 0`, `Fire 1`, or `Fire 2`

{% hint style="warning" %}
You cannot do two fires on the same frame on the same drone.
{% endhint %}
