I have set up a growth animation in Houdini and sent it over to UE4 over Houdini engine in HDA, but I can't animate the asset. The animation is not there basically, or I'm too blind to see it :\

In Houdini, I basically keyframed a parameter in the timeline. I tried to export that parameter to UE4 to animate it the same way in sequencer, but I can't see it there as well.

Not necessarily have to do it in Houdini Engine but the FB https://19216811.cam/ [19216811.cam]X export time is insane and when changing something it's a nightmare to export...

Does anyone have a best-practice workflow for this? I'm probably missing something in mine.

Houdini Engine will only generate a static mesh, alembic skeletal mesh workflow might work for you?
