# Emitter

## Description

Emitter is a drawing and particle emission canvas that creates animated particle systems as you draw. Unlike the Canvas tool, Emitter generates particles that emit and animate from your brush strokes.

## Setup

1. Open the Emitter tool
2. Adjust emission settings
3. Click record
4. Draw on the canvas
5. Add the recorded asset to the timeline

## Options

**Count**\
Number of particles generated per emission

**Distance**\
How far particles travel from the emission point

**Distance Variation**\
Randomizes the distance each particle travels

**Lifetime**\
Duration each particle exists before disappearing

**Scale Up Duration**\
Time it takes for particles to reach full size after emission

**Initial Size**\
Starting scale of emitted particles

**End Size**\
Final scale of particles at the end of their lifetime

**Birth Rate**\
Speed at which particles are emitted

**Color Variation**\
Randomizes particle colors with seed control

**Color Burn**\
When enabled, it equalizes the color burn over the layers

**Easing**\
Easing curve applied to particle motion and scaling
