TubeRig turns your flat wireframe bone controllers into thick, solid tubes — the way pro rigs actually look in production.

If you've ever squinted at a rig trying to figure out which thin line is a controller — this addon is for you.

What it does

TubeRig takes your existing Custom Bone Shapes and wraps them in procedural geometry, giving them real visual weight. No manual mesh editing. No extra objects cluttering your scene. Just clean, readable controllers that look great in the viewport.

Features

— One-click apply — select your armature, hit Apply Thickness, done
— Live thickness slider — adjust in real time directly from the Item panel in the N-Panel
— Per-rig memory — each rig stores its own thickness value independently
— Non-destructive — powered by Geometry Nodes, your original shapes stay intact
— Toggle on/off — switch back to the original wireframe look anytime
— Global defaults — set your preferred thickness once in Preferences, use everywhere
— Universal compatibility — works with Rigify, Auto-Rig Pro, and any custom rig using standard Mesh Custom Shapes

Who it's for

— Riggers who want cleaner, more readable rigs in the viewport
— Animators tired of hunting for thin wireframe controllers
— Anyone who likes how Control Rig looks in Unreal Engine 5 and wants that same visual clarity in Blender

Requirements

Blender 4.2 or newer · Extensions architecture · Any rig with Mesh Custom Shapes
