Timeline with Alembic track does not work

Hi all,
I am experimenting with Octane on unity. I use a timeline with some alembic tracks but the octane recorder does not update the alembic object.
I use the official AlembicForUnity plugin (https://github.com/unity3d-jp/AlembicForUnity)
Other objects are rendered with the correct animation, but alembic objects stay frozen at the first frame
Even with the realtime render preview window open I can scrub along the timeline and see all animated objects move except the alembic ones (they do update if I disable and re-enable them).

It seems like the octane plugin does not sense the alembic mesh needs to be resent to the octane render process, is there a way I can force the mesh to be resent? Perhaps it could be added to the ProcessFrame method in AlembicForUnity/AlembicImporter/Assets/UTJ/Alembic/Scripts/Timeline/AlembicShotPlayable.cs

We're working closely with Unity on this issue. There is no signal from Unity when a mesh data has changed, and without this, we would have to resubmit all data to Octane just in case something has changed. It would grind the applications to a halt, and you could never render more than a single sample (as Octane would reset every time data got resubmitted).

Due to these problems, we currently don't support these kind of animations.
