I want to automate RBD destruction simulation in an HDA in Unreal. Any tips or tricks to make that work? The RBDSolver node seems to not like being in an HDA.

The goal is to feed geo from Unreal to the HDA through the Object Merge node and pass it through an RBD Material Fracture, then RBD Solver nodes, and export the simulation through the Labs VAT output node.

Edit: It works if you add a File Cache node after the RBD Solver node.
