Fluid Effects > Create 3D Container with Emitter >

Emitter Name: Type a name for the emitter.
Parent to Container: Turn this option on to parent the emitter to the container. When the emitter is parented to the container, selecting the container automatically selects the emitter automatically.

If you intend to put your emitter on a motion path, you should create or add it unparented.

To unparent an emitter, select the emitter then choose Edit > Unparent.

Basic Emitter Attributes

Emitter Type

Select an emitter type.

Omni: Sets the emitter type to an omnidirectional point emitter. Fluid property values emit in all directions.
Volume: Emits fluid property values from a closed volume. You pick the shape from the Volume Shape option.

NoteIf you select Volume, make sure the emitter is bigger than one voxel.

Density Rate (/Voxel/Sec): Sets the average rate at which Density values are emitted into the grid voxels per second. Negative values remove Density from the grid.
Heat Rate (/Voxel/Sec): Sets the average rate at which Temperature values are emitted into the grid voxels per second. Negative values remove heat from the grid.
Fuel Rate (/Voxel/Sec): Sets the average rate at which Fuel values are emitted into the grid voxels per second. Negative values remove Fuel from the grid.
Fluid Dropoff: Sets the dropoff value for fluid emission. For Volume emitters the dropoff specifies how much the emission drops off as you move away from the volume axis (dependent on the volume shape). For Omni emitters the drop off is based on the emission point and radiates out from Min Distance to Max Distance.
Cycle Emission: Cycling emission restarts the random number stream after an interval in frames, specified by the attribute.

Setting Cycle Emission to Frame and Cycle Interval to 1 causes the random stream to restart every frame. Cycle Interval values greater than 1 can be used to generate cycles for games work.

This resets only the random stream used by the emitter. It does not reset the random number stream used by MEL, shaders, and so on. Note also that the Frame option resets at most once per frame. However, over sampling does not affect the results.
Cycle Interval: Specifies the number of frames between restarts of the random number stream. See Cycle Emission. Has no effect if Cycle Emission is set to None.

Distance Attributes

Max Distance: Maximum distance at which new property values are created from emitter. Not used for volume emitters.
Min Distance: Minimum distance at which new property values are created from emitter. Not used for volume emitters.

Volume Emitter Attributes

Volume Shape: Sets the shape of volume the emitter will use if the emitter is of volume type. Has an effect only if emitter type is Volume. Otherwise volume controls are disabled.
Volume Offset X, Y, Z: This is the parent attribute for the translational offset of the emission volume's center from the emitter's origin.
Volume Sweep: The arc of the volume emission. Used for sphere, cone, cylinder and torus.
Section Radius: Applies to torus volumes only. Defines the radius of a section of the torus.
