I'd like to split one network into subprocess' and assign them to specific Nodetrees. General idea is to have
Custom Execution Trigger on every subprocess to improve overall performance.
But how to transfer values between trees?
I can write/read values in Object ID properties, but they has limited use case, throwing error for Meshlist/Splines:
only floats, ints and dicts are allowed in ID property arrays
Also what is this interesting button Go to parent nodetree (green highlight)?:
