Weight Paint Box

A powerful add-on designed to make rigging and weight painting easier, faster, and more enjoyable.

What’s Inside

This add-on contains two essential tools in two clean, organized panels:

Draw Bone panel 
Quickly create custom armatures with built-in Rigify support, helping you set up rigs faster and more efficiently.

Weight Paint Box panel 
A smarter approach to weight painting—use a deformation box instead of the traditional brush for more control, precision, and flexibility.

Key Features :

• You can adjust the heatmap for a specific bone without needing to weight the entire character.

• Weight paint multiple separate objects at the same time

• The overlay section works in any mode

  So you can Weight paint in pose mode

• Smooth and unsmooth the heatmap by the smoothness circles  

• Add smoothing control points to each edge of the box — especially useful for bending areas

• Deform the box like a normal cube

• Automatically fit boxes to the target object in the list

• Deal with multiple vertex groups at the same time and mirror them

• View all vertex groups at once for a comprehensive overview

• Works with any rig

Ebb & Flow 
Lets you reshape the selected bone's vertex group by side without repainting it.

Ebb :
• fades the weights out towards the sides you choose. 
You can pick Above, Below, Left, Right, Front and Back, plus 8 diagonal slants with an adjustable angle. 

Fade Length: 
• sets how quickly the weight drops off: a short length gives a sharp cut, a long one gives a soft gradient.

Flow :
• does the opposite. 
It stretches the group further out towards the chosen sides, so its influence reaches more of the mesh. 

Flow only ever adds weight. 

At a Flow Length of 1 the group reaches twice as far.

You set the sides by dragging handles in the Ebb HUD, which shows the group from the front and from the side. 
Click a handle to turn that side on or off. 
Ebb and Flow keep separate settings and can be used together.  

Apply :
• keeps the result

Revert :
• puts back the original weights while keeping anything you painted since.

Important notes 

• Make sure to watch all tutorials before using the addon

• Make sure to parent the character to the armature using Automatic Weights before using the weight box.

• Make sure to use the boxes with the deformation bones

• If there are more than one box in the list, use the global options

Future updates :

Auto weight paint

It uses a hybrid algorithm that detects and handles both crowded and uncrowded areas in the same process.

Works with any rig setup, even imported characters like glb, glft, fbx, etc

 Will be released soon.

Take advantage of the low price before it's too late.

• The rest of the Rigify armatures
