Written entirely in Python and released under GPL-3.0, QuickPath RKNZ earns its place in the blender_extensions library for turning motion paths into a live, customizable, and organized viewport system. The developer reports testing on Blender 5.1 and 4.2, with a legacy branch covering 3.6.
QuickPath RKNZ is a lightweight motion path visualization addon for Blender that draws the paths of bones and objects directly in the viewport. Its real-time live update recalculates paths whenever you move a keyframe, and you can toggle that behaviour on or off from the top of the panel.
Instead of scrubbing through every frame, the addon samples bones and objects by evaluating F-curves and constraints directly. For rigs using supported constraints such as Copy Location, Copy Transforms, Child Of, and Damped Track, calculation is near-instant, and complex rigs fall back to a frame-set method automatically. Each path can be customized on its own: set the color, adjust line width, add sizeable dot markers, and enable separate before and after colors. The selected entry gets a soft glow in the viewport to identify it at a glance.
Entries can be grouped into named folders that collapse and carry shared front and visibility toggles, and checked entries support batch operations for applying parameters, recalculating, or clearing cached data. Per-entry frame ranges work independently of the scene, while a global range recalculates every entry at once. The addon is written entirely in Python and released under GPL-3.0.
QuickPath RKNZ is best for blender animators who want live motion path feedback on bones and objects, with per-path customization and folder organization instead of a flat, manually refreshed path list.
QuickPath RKNZ is completely free to download and use.
QuickPath RKNZ is listed here as compatible with Blender 4.2 LTS and newer. The main branch has been tested on Blender 5.1 and 4.2, while a separate legacy-extension-support branch has been tested on 3.6. The developer notes the addon was primarily tested on Blender 5.1 and can't guarantee it works on every version, so if you run into errors or bugs you're invited to reach out on Discord. For the current state of version support, check the developer's GitHub page directly.
QuickPath RKNZ is listed as free in this catalog and is released under the GNU General Public License v3.0 or later. That license governs how you can use, modify, and redistribute the code, which is written entirely in Python. Licensing terms can change over time, so for the most current details it's best to check the developer's GitHub page before relying on any specific arrangement for your own project or studio setup.
QuickPath RKNZ samples bones and objects by evaluating F-curves and constraints directly, rather than scrubbing through every frame the way Blender's native motion path calculation does. For rigs using supported constraints such as Copy Location, Copy Transforms, Child Of, and Damped Track, calculation is near-instant. When a rig is more complex, the addon automatically falls back to a frame-set method. This sampling approach is what lets it recalculate paths without the freezes described in the native system.
QuickPath RKNZ includes a real-time live update feature: paths automatically recalculate whenever you move a keyframe, so there's no need to manually refresh them the way the native system requires. You can toggle live update on or off at any time from the top of the panel. For manual control, per-entry frame ranges and a global frame range provide buttons to recalculate a single entry, all checked entries, or every entry in the list at once.
