Why we like it

NLA Tools earns its spot for addressing a specific gap in Blender's default NLA Bake, which covers only Location, Rotation, and Scale values — this add-on extends baking to bone custom properties. It is listed under the GPL and available free here.

What is Nla Tools?

NLA Tools is an add-on built specifically around Blender's NLA Editor, adding features aimed at speeding up work with it. Its main focus is baking: Blender's default NLA Bake handles only Location, Rotation, and Scale values, so NLA Tools adds a bake operator that also bakes custom properties on bones, such as a Rigify IK/FK switch. This is aimed at workflows that rely on layered animations.

The add-on also includes a Restrict Bake mode that tries to keep user-inserted keyframes when baking, along with a Blend operator for NLA strips, where Shift-click adds the default NLA blend, and a Delete Locked Properties command that removes keyframes of locked properties for selected NLA clips.

Further operators cover X-Mirror NLA Strip, linking selected NLA strips' action to the active strip's action, and extracting bones from NLA strips. An experimental Match NLA Strip operator can apply effects such as root motion. It is licensed under the GPL and lists Blender 4.4 as its supported version.

Who is Nla Tools best for?

Nla Tools is best for blender animators working in the NLA Editor with layered animations and rigs that use custom properties to drive IK/FK switching.

How much does Nla Tools cost?

Nla Tools is completely free to download and use.

Frequently asked questions

Does NLA Tools work with Blender 4.4?

NLA Tools lists Blender 4.4 as its supported version and is built specifically around Blender's NLA Editor. Its operators — the custom-property bake, Restrict Bake, the Blend operator, Delete Locked Properties, X-Mirror, and the others — all work inside that editor. If you are on a different Blender release, check the developer's page to confirm compatibility before installing, since the version listed here is the one stated for the add-on.

Why bake custom properties instead of using Blender's default NLA Bake?

NLA Tools addresses a limitation in Blender's default NLA Bake, which bakes only Location, Rotation, and Scale values and leaves custom properties out. Its bake operator handles custom properties on bones, such as a Rigify IK/FK switch, which matters for workflows that rely on layered animations. The add-on also includes a Restrict Bake mode that tries to keep user-inserted keyframes during baking. Together these operators are aimed at layered animation work in the NLA Editor.

Is NLA Tools free?

NLA Tools is listed as free in this catalog, and the developer also offers it for free on Gumroad. Licensing is stated as GPL. For current terms or any changes, check the developer's page, since availability can shift over time. The add-on is also noted as a Dev Fund Contributor entry. It is designed specifically around the Blender NLA Editor, so the tools it adds focus on that part of the workflow.

What NLA strip operators does NLA Tools include beyond baking?

NLA Tools includes several strip operators beyond baking. There is a Blend operator for NLA strips, where Shift-click adds the default NLA blend, and a Delete Locked Properties command that removes keyframes of locked properties for selected NLA clips. It also offers X-Mirror NLA Strip, linking selected NLA strips' action to the active strip's action, and extracting bones from NLA strips. An experimental Match NLA Strip operator can apply effects such as root motion.
