Output Generator Nodes

The output generator nodes output the different types of particle systems you can use.

Geometry Replicator Node

GeoReplicatorNodeLook01

The Geometry Replicator node generates geometry primitives onto the particles.

GeoReplicatorNode01

Geometry Replicator Parameters

Parameters

Description

Active

Toggle: Controls whether the Geometry Replicator Node is Active or Inactive.

Face Active Camera

Toggle: If this is active, the y axis of the geometry being replicated will face the camera for each replica.
If this is inactive, the particle or shape used will use its local orientations.

Orient With Active Camera

Toggle: If this is active, the y axis of the geometry being replicated will face the camera for each replica, and the x axis of the geometry will be vertical relative to the camera.
If this is inactive, the particle or shape used will use its local orientations.
If active, face active camera is ignored.

Rotation

Rotate the particle in X Y Z in degrees.

Aim

Aim points the particle in a specific direction in x,y,z.

Up

Change the ‘top’ value of the particle in x, Y, Z.

Scale Multiplier

Multiply the particle’s size in x,y,Z

Filter Object Index

When this is non negative, geometry will only be copied to the particles with this object index.
when this is negative, geometry will use the object index value in the emitter node.

Geometry Replicator Visualization

Output to Mesh

Toggle: When active, this node writes to the prim(s) specified but the ‘outputs mesh’.
When inactive: no prims are written to the particles.

Orient With Active Camera

Toggle: If this is active, the y axis of the geometry being replicated will face the camera for each replica, and the x axis of the geometry will be vertical relative to the camera.
If this is inactive, the particle or shape used will use its local orientations.

Rotation

Rotate the particle in X Y Z in degrees.

Aim

Aim points the particle in a specific direction in x,y,z.

Up

Filter Object Index

When this is non negative, geometry will only be copied to the particles with this object index.
when this is negative, geometry will use the object index value in the emitter node.

Visualizer Node

VisualizerNodeLook01

The Visualizer node outputs point visuals to the viewport only. There is no representation downstream and there is no data in the stage.
