This node is a subnet that contains a 
ROP Fetch TOP node and
a ROP Network with a 
Geometry ROP node. The parameters on
the Geometry node are promoted onto this node’s interface. Relevant parameters
from the ROP Fetch are also available, including controls for using this node
to cook work items for a distributed sim.
The subnet also contains a SOP network as a dive target, which can be used with the ROP Geometry. By default the built-in SOP network is disabled, and will only be used when the Use External SOP toggle is turned off.
Tip
If the SOP network you are cooking with this node is threaded (such as most simulations) you will be using most of the computer’s CPU resources. For this reason you should ensure that only one such work item is cooking at a time.
For the 
Local Scheduler, this means adding the
Single job parm on the ROP Geometry Output node and toggling it ON.
For the 
HQueue Scheduler, this might mean adding
and setting the CPUs per Job job parm.
