The fastest and most advanced rigging tools for Blender with modular scripted features!
This is only the initial release, there is a lot more to come! (and if you try to break it... it's gonna break lol)
Armature Rigging Modules is a Blender add-on that provides modular rigging for almost any armature which can be as simple or complex as you need it to be and setup in a fraction of the time the manual process takes, not to mention all the advanced scripted mechanics.
It can quickly and easily setup rigging for your characters that includes soft IK, automatic IK vs FK switching and a host of other useful features for arms, legs, feet, hands, spines and heads and that's just the beginning. This add-on is one of my favourites to work on and has already saved me hundreds of hours so it will be getting many updates, further additions and future development.
You can get it for free on Gumroad! Donations appreciated.
