This task is for user feedback and possible design decisions for D1783 (alembic_basic_io branch).
A quick and dirty, WIP, documentation can be found here.
Here's a quick description of the state the Alembic implementation:
Support as import/export
Exports the scene (or individual objects) as an Alembic archive similar to FBX and Collada.
Import is limited, since geometry streaming is not be supported, only the first frame (time 0.0, in Alembic terminology) is loaded. Perhaps it is desired to expose some setting to choose which time to load.
Support as an extra format for "Mesh Cache" modifier
This reads data for the object the modifier is attached to from a given Alembic archive. The object's path is in the Alembic archive needs to be passed to the modifier as well. For now, only mesh objects are supported.
