FlexyTrack is a Blender add-on that adds physics-free Damped Track rigging to chains of bones. When you animate a model, the main bone isn't the only thing that moves. Subsequent bones follow it with a slight offset, producing a natural delay effect that suits moving elements.
To do this, FlexyTrack uses the Damptrack constraint and automates the rigging of a chain of bones. That automation is the heart of the add-on: rather than setting up each constraint by hand, you let FlexyTrack handle the chain so animated bones carry that trailing motion. It's aimed at avoiding robotic-looking animation on parts like a ponytail reacting to a character's movement, fins, or a twitching mustache.
Developed by MignotGeorges and released under the GNU General Public License v3.0 or later, FlexyTrack is compatible with Blender 4.2 LTS and newer. The extension requires no special permissions and is small in size, available through the Blender extensions platform by dragging it into Blender or installing from disk.
