Aligorith’s Lair: Rigger Service Announcement – Time to Update Your Rigs Again

Aligorith’s Lair: Rigger Service Announcement – Time to Update Your Rigs Again.

In the same vein as public service announcements, I’d like to take this opportunity to alert riggers out there to some recent changes to the RNA/Py-API that cause some rig breakage from 2.56 to 2.57.

A recent commit (r. 35764) by Campbell will break ShapeKey Drivers and/or ShapeKey Animation, as the “keys” collection in the “Key” ID-Blocks (i.e. container for ShapeKeys) has been renamed to “key_blocks”, to avoid conflicts with Python’s builtin datatypes.

Recommended Remediation Procedure:
Run the “FCurve/Driver Version Fix” operator from the Help menu.
– You will need a build of at least r.35804 35808 to do so, as Driver F-Curves were not fixed by this operator prior to this commit
