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.
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.
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.
A path to the POP to cook. If it points to a POP network, it will use the cook POP of that network.
