Loads the geometry from a pop network back into this Geometry object as points.
This SOP uses an external POP network to run a particle simulation. It will import the state of the external POP network using the provided parameters. By connecting SOPs to the inputs of this SOP, one can override the Context Geometry which is used by the POP network.
Tip
To jump to the POP network, press 
on a POP Merge node tile
and choose Edit POP Network. This also sets the View Operation
parameters of the POP viewer to match those of the POP Merge node.
Context Geometry
All POP networks can have 'Context Geometry'. These context geometries are set in the parameters of the POPNET, the Particle CHOP, or the Pop Merge SOP. In the Pop Merge SOP they can also be set by wiring OPs into the inputs of the operator. These context geometries can be referenced by the following POPs: Source POP, Collision POP, SoftBody POP, Attractor POP, Creep POP (All of which have the parameter - Geometry Source > Use Context Geometry). So, instead of hard-coding a specific piece of source geometry or collision geometry, a single POP network can be used by several Pop Merge SOPs to generate several different outputs, depending on the geometry input into the Pop Merge SOP.
Parameters
| POP Path | A path to the POP to cook. If it points to a POP network, it will use the cook POP of that network. |
Standard
| Start Time | Time at which simulation starts, based on seconds using the FPS of the scene. |
| 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. |
Input Geo
| 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. |
