What is Rigify Retarget?
Rigify Retarget is a plugin aimed at improving Rigify substantially by introducing non-destructive rigging, a more streamlined setup process, seamless armature updating, and easy baking tools to make the use of any armature, a comfortable and consistent experience, no matter if it’s humanoid or not, connected armature or not, nothing is out of reach. Specially useful for game armatures.
The first linked video gives an explanation on all the features the plugin has to offer, and the second is a longer video on how the plugin is used and how to use it as efficiently as possible.
Features
- Fully non-destructive workflow.
- You can Rigify anything, not limited to humanoid armatures.
- All important toggles in one convenient place.
- More understandable setup process, with bones colored based on what Rigify type they have.
- Operators to solve common armature problems in a single click.
- Bone layer presets.
- Seamless armature updating, all animation data & parameters preserved between generations.
- One click baking tools.
- Automatic bone sorting to layers for humanoid rigs.
- All Rigify rig parameters available.
- Generated rigs can be freely used by anyone even if they don’t own the plugin, including the baking tools.
- Enhanced layer list to easily move bones to the correct layer.
- Automatic fixing of common Rigify errors.
- Clarifications for unhelpful Rigify errors.
- Custom name support for more streamlined naming or posing symmetry.
- Additional parameters to make animation more comfortable if you don’t intend to export it to other platforms.
Why was it created?
For a long time i have had to work with game armatures of various types, they are simple for the best performance in games, but that doesn’t make them very animator friendly. When i wanted to create fancy animations for them, i was required to use simple IK constraints and deal with the many imperfections of it, or take multiple hours setting up a constraint system bone per bone to control it with a Rigify rig.
It was a really long and tedious process, not only to setup, but also to work with, because when baking, i had to get rid of all constraints to make sure the bake was done properly, and then undo, and doing that every time you make an animation change or with many animations gets tiring very quickly.
This plugin was made to shorten the time it takes to setup an armature as much as possible while still making the most use of the many features Rigify has to offer, and while keeping it non destructive to preserve compatibility when porting back to games.

Where can i get it?
It is currently available in my Ko-fi shop, and coming to Blender Market in the future. Documentation for it is readily available and any bugs can easily be reported through the Github page, if you have any question you can ask in this thread or ask me directly through Twitter
There is no difference between the two versions of the plugin, if you have a bigger team and can afford to spend more to support me, it would be much appreciated!
