NOTE: If github downloads the file with a longer name than just "Rigodotify.zip" rename it to just the base name before install.

A dual purpose Rigify feature set and Blender rig converter plugin. Recently reworked to add compatibility across all major game engine retargeters: Godot, Unity, and Unreal standards are used to make retargeters auto-detect bone structure and more happily share animations across models.

Rigs can be converted in a button press to make them game engine compatible. Convert the rig before parenting it to your mesh and your model will be ready for animating for games!

Bonus metarigs optimized for for Quaternius Animation packs, Base Characters and Clothing kits!

Purpose:

Skeletons and rigs used for game development are distinct to those used for animation. They tend to be placed in T-Pose, have far fewer bones, and a hierarchical bone order. This makes animations more efficient for processing and also aids in animation transferring to other characters, and keeping in-engine IKs working as expected.

This plugin and feature set produces standard Godot, Unity and Unreal skeletons  with extra Rigify bones removed, the bone order fixed, and friendlier names given for mapping them in engine. Leaf bones are added for Unreal, and constraints adjusted to minimize scale errors, and animation jitters in engines.

FAQ:

• It won't install? Make sure the file name is "Rigodotify.zip
• It throws errors and won't generate the new rig?! Make sure the rigify rig is named something normal like "Armature" or "rig" and not a multiple of the rig like "Armature.001" etc. 
• Still not working? Try deleting former rigoditified rigs, their WGTS_rig objects, and even hit "Purge" in the "Unsued Data" section to remove old rig references and give it a truly fresh start.
