At our studio we are using the UE v1 plugin and have geometry generated from UE Splines wrapped inside BPs.
These go through a relatively complex HDA to create static geo.
I've noticed that it can happen that if spline points are modified rapidly across several Houdini Actors, it can hang the HAPI process and potentially crash UE.
It makes me wonder how the Houdini Engine plugin handles this case: lots of changes across multiple actors all happening before the engine can even finish processing one network change.
More importantly, are there known issues where this can lead to hangs/crashes? Some of our Houdini Actors use multiple splines and we've seen some crash dumps that suggest the arrays of input splines can get boggled between actors during processing, possibly resulting in the hang/crash.
Thanks for any thoughts.
