Box Emitter component as seen in the Scene Inspector
Box emitter is a component that is used in conjunction with Particle System and Particle Style. It allows for adding particles into a Particle system with a rate, and does them inside or along the outside of the box area specified. The particle starting colors are lerped based on what corner of the cube the particle generated is closest to.

persistent
|
Bool | Determines whether or not this item will be saved to the server. |

|
Float | the min value of the range of particles to be emitted when activated. |
BurstOnActivatedMax
|
Float | the max value of the range of particles to be emitted when activated. |
BurstOnStart
|
Bool | Shoots a burst of particles when the component is spawned in. |
Size
|
Float3 | The size of this box emitter. |
EmitFromShell
|
Bool | Enable emitting particles on the outside of the box instead of from any point within the volume. |

DirectionTransformMode | How to determine the transform of the particles |
RandomDirectionWeight
|
Float | How much random velocity to add to the particles. |
DirectionPostTransform
|
Float3x3 | The direction the particles should face as an extra matrix transform after the final particle starting direction has been calculated. |

Usage
Used in creations using particle systems as a source of particles.
Examples
Useful to make fireflies in an area, for a calming nighttime aura. It can also be used to make leaves fall from trees by making a box around the tree leaves, or as wind particles in a breezy field.
