Vellum has this notion of putting geometry and constraints in separate data objects in DOPs, which complicates updating both Geometry and ConstraintGeometry in sync using wrangles and VOPs, since they can write only to the input geometry.

What's a good approach for, say, creating new geometry and constraints for it purely in DOPs? One use case would be doing something like this https://vimeo.com/247761862 [vimeo.com] in Vellum instead of POP Grains, where new geometry and constraints are made based on the current simulation state.

So I eventually figured out a way, but it's kinda obscure.

Apparently the SOP Solver can be set up to input AND output multiple data objects by enabling “Invoke Compiled Block”. Turns out a compiled SOP network can have multiple outputs. Who knew?

Maybe will be usefull.
