POP Network surface node

Contains a Particle node network.

This node lets you embed a particle network inside a Geometry object. See particle network nodes.

You can reference any geometry you connect to this node’s inputs as “context geometry” inside the particle network.

The DOP Import tab lets you override the output of the SOP with the result of a DOP Pop Geometry.

Parameters

Start Time	Time at which simulation starts
Preroll Time	At start time, simulation has already been running this long
Initial State	Geometry to use as initial state of simulation
Random Seed	This value is used to initialize the pseudo-random sequence used by the simulation. It is useful for generating different simulations from the same network.
Oversampling	How many times to cook in between frames
Max # of Particles	Controls the maximum number of particles that can exist in the simulation at any given moment. A value of 0 means particles can always be birthed.
Remove Unused Points	Remove the points associated with dead particles. This can reduce the memory footprint of the simulation. On the other hand, disabling this option can improve performance by recycling points. Changing this option can affect the point numbers associated with individual particles.

SOP N

The path to a SOP to use as Context Geometry N.

The display or render SOP can be specified using paths of the form object_path/display_sop or object_path/render_sop, respectively.

DOP Network	The DOP Network to extract the particle system from. If blank, will not attempt to extract anything.
Object Mask	Specifies the objects within the DOP Network to extract the simulation from. Only the first object matching will be used.
Geometry Data Path	The name of the subdata that contains the pop simulation to extract from DOPs. It should be of type POP Geometry.

Example name	Example for
