Spawn on Trigger

This compound emits a particle explosion of new particles when a trigger value is reached in a state system.

Plug its Execute on Trigger output into a Port on the ICETree node or into an Execute on Trigger port of a State compound, if you're using a state system.

For more information, see Spawning Particles Upon Trigger [ICE Particle Simulations].

Tasks: Particles/Spawning

Toggles the activeness of this compound.

Spawning Parameters

Target Cloud Reference	The point cloud whose particles you want emitted when the original particles collide with an object. Use the Explorer button to find the point cloud or enter its name in the text box.
Target Cloud Name	Name of the point cloud to which you're spawning.
Number to Spawn	The number of particles you want to create (per second) when the trigger value is reached.
Delete Source Point	Deletes the source particle from which the spawned particles are emitted.
Enable Spawning from Spawned Particles	Toggles the continuous spawning of the spawned particles. If this is off, the particles spawn only once upon emission.

Direction and Speed

Inherit Particle Speed	The spawned particles inherit the speed of the original particles from which they are spawned. If this value is 1, the speed equals the speed value of the original particles.
Spawn Direction Start Angle	The Start and End Angles create the angle area in which the particles are spawned around the point of emission. Angle values of 0 - 360 is the full rotation range.
Spawn Direction End Angle	The End Angle of the angle area in which the spawned particles are emitted.
Spawn Speed	Speed of the spawned particles in Softimage units per second.

Set Initial Values

State ID	Gives each State a unique ID so that the particles in that state can be easily identified. If there are two states that have the same ID, only the state that is plugged in first into the State Machine will be evaluated.
Initial Value	The particle attribute you are setting for the spawned particles.
Initial Value Reference	You can add an attribute here to change an aspect for the spawned particles, such as their Size, Mass, Shape, Orientation, and so on. Enter the attribute name here or use the Explorer button to select the spawned point cloud's attribute name.
Execute on Spawn1	Executes whatever compound is plugged in here at the time that the particles are spawned.
