ParticleData 

The ParticleData Helper is used to get many aspects of the currently selected particle Group so that this information can be passed along to other operators and conditions.

ON - (Bool) This input data stream determines whether the operator is considered 'on' or 'off.' You can connect other operators to this input channel such as a Bool Helper to activate/deactivate the whole operator.

Time - (Time) This input data stream is used to define the local time for the operator when the user wants to override the default system time.

Particle - (Particle) This input data stream reads in the currently selected particle group that is to be used for it's data channels. The data stream MUST be connected and will be highlighted yellow if it is not.

Position - (Position) This output data stream provides the position of the particles for other operators and rules to act upon.

Velocity - (Velocity) This output data stream provides the current velocity of the particles for other operators and rules to act upon.

Life Span - (Life Span) This output data stream provides the life span of the particles for other operators and rules to act upon.

Age - (Age) This output data stream provides the current age of the particles for other operators and rules to act upon.

AgeRelative - (Scalar) outputs the particle age between 0 (birth) and 1 (death).

Size - (Size) This output data stream provides the size of the particles for other operators and rules to act upon.

Rotation - (Rotation) This output data stream provides the rotation of the particles for other operators and rules to act upon.

Alignment - (Alignment) This output data stream provides the alignment of the particles for other operators and rules to act upon.

Mass - (Mass) This output data stream provides the mass of the particles for other operators and rules to act upon.

Scale - (Scale) This output data stream provides the scale of the particles for other operators and rules to act upon.

Group - (Group) This output data stream provides the current particle Group the particles belong to for other operators and rules to act upon.

Shape - (Shape) This output data stream provides the shape information of the particles for other operators and rules to act upon.

Position +dt - this will give you the position for the current sub-sample calculation

Alignment +dt -  this will give you the alignment for the current sub-sample calculation

CH: is displayed whenever a data channel is used in the selected particle group
