Emit from Null

This compound emits new particles from a null's centre.

Plug this compound's Emit output into the ICETree node. This compound should be plugged in to the first port of the ICETree node because you usually need to emit particles before any other node or compound can be evaluated.

For more information, see Emitting Particles from Nulls [ICE Particle Simulations].

Tasks: Particles/Emitters

Output Ports: Emit

Enable

Turns the particle emission on and off.

Emission Parameters

The other Emission parameters are the same as the Emission parameters in the Emit from Geometry compound.

Null Name

The name of the null that you want to use as the emitter. Plug the null's Out Name output into this port.

Initial Values

These parameters are the same as the Initial Value parameters in the Emit from Geometry compound.

Direction and Speed

The other parameters are the same as the Direction and Speed parameters in the Emit from Geometry compound.

Randomize Direction Start Angle	Randomizes the direction of the particle as they're emitted within a range as defined by the start and end angles. These values are in degrees.
Randomize Direction End Angle	The end angle of the range in which particles are randomized.
