Alembic can output cameras. It is critical to be able to import an animated camera into CS in order to 1) follow a moving object while sculpting 2) sculpt for silhouette etc based correctly on the lens.

This along with the importing/exporting of multiple animated meshes (from one alembic file / and back to one alembic file) are the biggest showstoppers of the tool. Correct these and this will be a good tool in production.

Thanks.
