Short description of error
I'm on the latest nightly build and still there are some showstopping issues with linked objects that have alembic cache files applied to them. If you retime the cache via the override Frame option on the original file to be linked, the animation on the linked files goes poof.
Exact steps for others to reproduce the error
Open the provided scene file. (
Retime one of the objects' cache via override frame and save over.
Link in the group that contains the object you retimed previously into a new scene.
Scrub and see nothing happening.
You can return to the provided file, uncheck override frame and relink to see that the default animation from the abc file functions. It is the frame override that gets unread once checked and animated.
