Foot Lock earns its place in the superhive library for a focused job: clearing foot slide from mocap takes with a three-button workflow and non-destructive, NLA-based editing.
Foot sliding is a common challenge in lower budget motion capture setups, and Foot Lock is a Blender add-on built to clean it up. It lets you lock a character's feet in place during animation and adjust how long each lock lasts, so you can refine mocap data without redoing takes.
The add-on works from a simple three-button design. Locking a foot automatically generates a Non-Linear Animation (NLA) strip, and you set the lock's duration by scaling that strip in the NLA workspace. You can fine-tune placement by adjusting the location and rotation of the empty object tied to each lock. Foot Lock works with IK rigs, FK rigs, or a combination of both, and edits are non-destructive, preserving the original mocap data.
Foot Lock supports Blender versions 2.8 through 4.5 and is not compatible with Blender 5.0 or later. It's compatible with various mocap setups, including Kinects and iPiSoft Motion Capture Studio. The add-on is released under a GPL license, and a demo video is available.
Foot Lock is best for cleaning up foot sliding in motion capture animation within Blender, particularly footage from lower budget mocap setups.
Foot Lock is completely free to download and use.
Foot Lock supports Blender versions 2.8 through 4.5 and is not compatible with Blender 5.0 or later. If you're on a supported release in that range, you can use the add-on to lock feet and clean up sliding in your mocap animations. For newer Blender versions, check the developer's page to confirm current compatibility before installing, since the listed range stops at 4.5. Staying within the supported versions helps ensure the NLA strip creation and foot-lock tools behave as intended.
Foot Lock works with IK rigs, FK rigs, or a combination of both, so it fits a range of character setups. Once a foot is locked, the add-on generates an NLA strip and an empty object whose location and rotation you can adjust to fine-tune placement. Because editing is non-destructive, your original motion capture data stays intact while you refine foot positions. This makes it usable whether your rig relies on inverse kinematics, forward kinematics, or a mix of the two.
Foot Lock is compatible with various motion capture setups, including Kinects used with iPiSoft Motion Capture Studio, as well as other mocap systems. It targets the foot sliding that often appears in lower budget mocap workflows, letting you lock feet in place and adjust each lock's duration by scaling its NLA strip. Since it edits non-destructively, you can experiment with foot placement without altering the source data. The add-on doesn't depend on a single capture system, so it can fit into your preferred pipeline.
Foot Lock is listed as free here and is released under a GPL license. For current licensing terms or any pricing details, check the developer's page, since these can change over time. The add-on cleans up foot placement in motion capture animation within Blender, using a three-button workflow, automatic NLA strip creation, and non-destructive editing that preserves your original data. It works with both IK and FK rigs and supports Blender versions 2.8 through 4.5. A demo video is also available.
