Hi, yes you totaly right As i said, it's not new, a long time ago i also saw some things about i did some research and yes it seems to be close from Houdini methods, not sure it's completely the same.
And you also right about modularity, my autoRig proto is build in this way, you can install and uninstall systems on a chain etc. It's cleaner, AND less cpu consuming. And i think this is the method you need to have on autoRig system.
I'm in test, i need to run the system in a fully rigged character , i need to play with some spaceSwitch tests etc, to control all those things and be sure it's ok on a production rig.
And think about some automation after, sooo looooott of work to do.
For now, it works on FK, IK and IKStretch, so i think it will work because all other rigs are attached to ikStretch or bind chain, so.
I keep you in touch when i get something robust and complete and will breakdown it.
Once again, yep, not new, it's not a magic feature and as i said i'm pretty sure many riggers got it and have some systems close to this one, no doubt.
At the moment, the problem is performances, the guide system is not free talking about ressources. It's a "save your production" feature, just in order to react very late retakes from agency or clients.
