About

Character rigging and animation are quite complex nowadays.
This addon is another attempt to make it easier.

Current version is 1.1.8 and it works for blender 4.1

Here is the repository with demo version and sample scene.
It doesn't allow to create rigs,but works with existing ones

For blender 3.x use version 1.1.6

Here is the manual, issue tracker,voting for upcoming features and some videos about this addon

Features

• Turn basic armature into the animation ready rig in a couple of clicks
  
• Any bone can be pinned
  
  
  
  
• You can change bones hierarchy on the fly
  
  
  
  
• Pin/unpin bones during animation to control interpolation between poses
  
  
  
  
• Different posing modes (see manual for details)
  
  
  
  

• Character skeleton may have loops
  
  
  
  

• Rig can split into parts during the animation
  
  
  
  

• You can animate objects in the same way as bones
  
  
  
  

• Most of the features can be accessed from the pie menu
