Bone Widget is a blender add-on to assist with making custom bone shapes. It has an editable library of shapes that make it easy to apply to any rig.

It ships with many shapes pre-made but you can also add your own to the library to make rigging easier.

1. Download the zipped code here from Github. (Check in the release tab for the latest stable release)
2. In Blender, open Preferences->Addons->Install. Navigate to where you saved the zip file and click install.
3. Enable the Addon with the checkbox.
4. The UI will appear in the properties panel (n panel) in the 3d viewport.

This will show/hide the large widget preview panel. It's also possible to set your preferred option for this in the preferences. (The default is enabled)

This is the large preview panel that displays the currently selected widget. Click on this panel to open the selection menu.

This is the active shape from Bone Widget Library.

To add a mesh object to the library, select a mesh object and click this button. Give the mesh object an appropriate name and then confirm. Your widget will be added to the library. (User widgets are stored in a separate json file to the shapes that come with the addon.)

This will remove the active shape from the library. Select the shape you want to remove from the list. And click this. Boom, it is gone (forever!). This will work on any widget in the list.

It is possible to inport and export all the custom widgets that you have added to/from a zipped json file. This will let you more easily share them with another computer.

This function will let you assign an image from you hard drive to use as the widget preview.

Select a bone (or bones), choose the shape from the drop down menu, then press create. This will create a widget object for each of the selected bones. The widget objects will be placed in the collection that is specified in the user preferences.

When enabled the Global Size will be multiplied by the bone length. (ie - the widget will be relative size to the size of the bone) With this disabled, the Global Size will be in Blender units.

If the widget that has been added has faces, you can choose to show them with this setting. This will either include or exclude them when the widget is built.

This will be the size of the widget, relative to the size of the bone if 'Scale to bone length' is enabled. Or in Blender units if that setting is disabled.

When the advanced options is enabled you can access the individual scale channels of the created widget, rather that 1 scale value for all 3 axes

This will slide the position of the widget along the Y axis (or length) of the bone. 0.0 is at the head of the bone and 1.0 is the tail. (negative values are possible too)

When advanced mode is enabled, the slide property is split into 3 axies rather than just the defalt y axis.

You can rotate the widget by these values at the time of creation. This can save you from having to jump into edit mode to rotate a widget to better align with your situation.

This will let you set the wireframe thickness. The default setting is 2.0 but Blender will allow any float between 1 and 16.

This checkbox will switch the slide value into 3 axes rather than just the default Y axis. This will enable the user to position the widget in some situations without having to jump into edit mode.

When in pose mode, this will jump into edit mode for the custom bone shape and allow you to edit it. When you have the shape selected (object or edit mode), this button will display as "To Bone". That will take you back to pose mode, if that mesh object is in face a custom shape.

Note on Creating and Editing Shapes:
When you 'Create' a shape, it will always be placed in the collection set in the user preferences.
If you 'Edit' a shape, it will stay in whatever collection that widget was already located.

If the widgets get out of alignment with the location of the bone itself, this operator will snap the selected widget to the matrix of the bone. It works if you have the bone(s) selected or if you have the widget object(s) selected.

Sometimes you might rename a bone/or a widget. This operator will loop through all the custom bone shapes and make sure they match the name of the bone they are assigned to.

Note: Currently the add-on is designed to have one widget per bone, if you have multiple users of the same widget, it will be renamed to the last user it finds.

This will clear the custom bone shapes from all the selected bones.

This operator will loop through the widget collection and delete anything that isn't being used. This helps keep things tidy.

If you want to apply a mesh object that is already in your scene as a custom shape, you can use this option. First select the mesh shape you want to use (object mode), then shift select the armature, switch into pose mode and make sure you select any bone(s) you want this shape to be applied to. Then press the button.

As the name would suggest this will toggle the visibility of the widget collection.

Note: This will only toggle the visibility of the designated widget collection (set in the preferences). If your character has widgets outside of this collection, it will not toggle the visibilty of that.

With this enabled the addon will use the same naming convention for the widget prefix and collection name as Rifigy. If this setting is disabled you can set them to your preference.

If the "Use Rigify Deafaults" is disabled, the addon will append this text to the start of every new widget created.

If the "Use Rigify Deafaults" is disabled, the addon will use this as the collection to place all the newly created widgets. If a widget already exists when you edit it, it will stay in the collection it already belongs to. The addon will not move existing widgets.

This will let you set the suffix that is appended to the end of the symetrical widgets.

This is the name of the panel the addon will be displayed in.

This boolean will let you set the default state of the Preview Panel. You will still be able to turn in on/off with the checkbox in the main ui, but advanced users probably don't need to see the large preview all the time.

You can set the size of the Preview window with this setting.

This will set the size of the images when you activate the popup widget panel.

If you have accidentally (or purposefully) changed the images for any of the widgets that the addon ships with, this operator will reset them back to their original images.

• [Added] Markus Berg added functionality to display images of the widgets. What a flippin' legend.

• [Added] added wire width option when the widgets are created
• [change] remove the "_old" functionality of the code (just delete the old widget)
• [fix] the match bone transforms now takes the custom shape transforms into account
• [fix] if the collection didn't exist when you tried to delete unused widgets it would throw an error. You now get a message that hints at the problem.

• [Fix] widget collection no longer needs to be in the master scene for the addon to find it.
• [Fix] All the related functions now search for the collection recursively so the structure of the Widget Collection location doesn't matter.
• [Fix] change the mirrorShape function to only display in pose mode to avoid errors.

• Fix: updated to work with Blender 2.93/3.0
• Functionality change: If you are editing a Widget that already exists, it now will use the collection where it is actually located rather than trying to find it in the user preferences settings (fixes error if the collection was called something different)

• Renamed 'FK_Limb' to 'FK Limb 1'
• Renamed 'Arm' widget to 'FK Limb 2'
