Hi, do DOPs work in HDAs? I've been trying for a while to use some sims to deform geo but it seems to not work.
I assumed it would be okay since the landscape sim works with a timeshift to lock the frame. I've tried sop level vellum solver and also inside a dopnet but they seem to fail to output when I'm generating the HDA in Unreal.

I have this exact issue as well. Trying to make some simple vellum sims and timeshift/lock sim to frame 1 but getting sim errors with the HDA.

This also happens to me. Have you found a workaround?
