  Determines the depth of the emitter shape.

• - emitterMode

  Specifies the emitter mode.

• - emitterPosition

  The position of the center of the particle emitter.

• - emitterShape

  Specifies the emitter shape.

• - emitterSize

  Determines the size of the particle emitter shape.

• - emitterZPosition

  Specifies the center of the particle emitter shape along the z-axis.

• - lifetime

  Defines a multiplier applied to the cell-defined lifetime range when particles are created.

• - preservesDepth

  Defines whether the layer flattens its the particles into its plane.

• - renderMode

  Defines how particle cells are rendered into the layer.

• - scale

  Defines a multiplier applied to the cell-defined particle scale.
