Why we like it

RigFlow earns a spot in the superhive library for treating rigging as a drawing task: sketch a path, refine joints directly, mirror across an axis, and generate an armature with automatic weights in one step.

What is Rigflow - Interactive Rigging Tool?

RigFlow turns rigging in Blender into a visual, sketch-driven process. You draw the path you want your bones to follow, and the add-on generates a segmented chain or an extrusion from it. Two drawing modes cover different needs: Draw Mode sketches a free-form path that becomes an entire bone chain at once, suited to organic limbs, spines, and tails, while Extrude Mode creates bones one at a time by clicking and dragging.

Once a chain exists, you can grab and reposition any joint, including intermediate ones, and the rest of the chain adjusts in real time. Mirror Mode duplicates and mirrors every path you draw across the X, Y, or Z axis. Path ends can snap to existing bone chains to build branching skeletons, and the Auto-Connect feature parents bones whose heads and tails coincide. A Bone Segments slider sets how many bones a drawn path divides into.

When the structure is ready, Generate Bones builds the final armature, connects the bones, and parents your mesh to the rig with automatic weights. The workflow is non-destructive, with Undo and a Clear All function. RigFlow supports Blender 4.3 to 4.4 under a GPL license.

Key features

  • Dual drawing modes: Draw Mode sketches a free-form path into a full bone chain, while Extrude Mode creates bones one by one by clicking and dragging.
  • Interactive joint manipulation lets you grab and reposition any joint, including intermediate ones, with the rest of the chain adjusting in real time.
  • One-click Mirror Mode automatically duplicates and mirrors every drawn path across the X, Y, or Z axis.
  • Intelligent path snapping joins path ends to existing bone chains, and Auto-Connect parents bones whose heads and tails coincide into a connected hierarchy.
  • Live visual feedback shows bone structure and volumetric envelopes updating as you draw, with adjustable envelope opacity.
  • Customizable bone resolution through a Bone Segments slider that sets how many bones a path divides into.
  • One-button armature generation builds the final rig, connects the bones, and parents your mesh with automatic weights.

Frequently asked questions

Which Blender versions does RigFlow support?

RigFlow supports Blender versions 4.3 through 4.4. Within that range you can sketch bone paths and generate a full armature, with the add-on parenting your mesh to the new rig using automatic weights when you press Generate Bones. If you're on a different Blender release, check the developer's page to confirm compatibility before installing, since only the 4.3 to 4.4 range is given for this version of the tool.

How does RigFlow create symmetrical rigs?

RigFlow handles symmetrical characters through its Mirror Mode. When it's active, every path you draw is automatically duplicated and mirrored across the X, Y, or Z axis, so you rig one side and get the other in the same action. This pairs with intelligent path snapping, which lets path ends join existing bone chains, and the Auto-Connect feature, which parents bones whose heads and tails coincide into a connected hierarchy. Together these let you build symmetrical, branching skeletons without placing each mirrored bone by hand.

Is RigFlow free, and what license is it under?

RigFlow is listed as free in this catalog and is released under a GPL license. For current licensing terms and any related details, check the developer's page, since those can change over time. However you obtain it, the add-on's feature set stays the same: dual drawing modes, interactive joint manipulation, one-click mirroring, path snapping, live visual feedback, and one-button armature generation with automatic weights. The GPL license governs how you can use and redistribute the add-on.

Can I undo changes while rigging with RigFlow?

RigFlow uses a non-destructive workflow, so you can experiment with bone placement without committing to it. Standard Undo works with Ctrl+Z, and a Clear All function bound to Ctrl+C removes your current work so you can start over. Because you can also grab and reposition any joint in a chain, including intermediate joints, refining a rig is a matter of dragging points rather than rebuilding, with the rest of the chain adjusting in real time as you move things.
