As 3D Artist Thomas Bittner explained, this Auto Scapula lock for dog and horse limbs will help animators put the body weight onto the scapula without having to counter-animate. While the Maya part in the video is currently available in the latest Kangaroo-Builder version, the artist hopes to publish Unreal Engine rig builder later this year.
Kangaroo-Builder is Thomas Bittner's custom framework for rigging in Maya, a dream project of an ultimate rigging toolset, a complete system that includes rig builder, tools for face rigs, a pipeline for collaborating and sharing within your team and creating backups, skinning, weight maps, and geometry tools.
You can get a first impression of the main Kangaroo-Builder tools by watching these videos and then check out all 30 tutorials provided by the artist:
