My tips

Guided Sim:

• When using a simple guided sim connected to the Solver's Guides input you need to disable "Use Preconfigured Setup" in the Solver's advanced settings. That option I guess is needed when you use the RBD Guides node to set it all up.
• When using a POP particle system as guides, the points themselves are not enough, it requires full primitives, not even particles connected into poly lines. Use Connect Adjacent or CopyToPoints to get some geo moving.

RBD speedup

Redshift can be really slow with degenerate primitives created by Voronoi Fracturing. Unpack & add Clean SOP before sending to RS.
Also delete all unnecessary attributes before unpacking, especially sim attributes generated by the RBD solver. Each attribute adds a little bit of time to the unpack and to the RS scene extraction!
