Hello,

I have built an HDA for use in UE5.1
All data is created in Houdini and sent to UE5 (there are no UE5 inputs those seem to crash unreal for me (separate topic)).


I want to expose a few settings (width, length, vellum settings) on a curtain and simulate it for 100 frames, then send that geo to UE5.
Currently it is just sending the geometry from frame 1 to Unreal.
How do I tell the HDA to simulate for 100 frames?
Is there a "frame number" parameter, I'm missing?

Any help is appreciated.

Cheers,

Add timeshift node after vellumsolver and set it to whatever frame you want as output or... switch Simulation Type in solver from dynamic to Quasistatic. and if you don't turn off Enable Automatic Resimulation it will update automatically so no need to press Reset Simulation.
