Hi,
I asked some developers a while back about the discrepancy between interactive performance in Houdini Engine for Unreal vs. other implementations like Unity and Maya. Unreal was far far slower. I was told that the mesh rendering enhancements in Unreal 4.22 would allow Houdini Engine for Unreal to have parity with the other implementations. I've started testing HE in UE4.22 and it does seem much faster than before, but it still doesn't have the interactivity of the other implementations. You can't see meshes update as you are adjusting parameter sliders. It seems like it's locked into “On Mouse Up” type update mode. Is that the expected behavior? Dialing in your values without any visual feedback is still a major disadvantage vs the Unity and Maya versions of Houdini Engine.
