Yep, I know about this plugin. I think free version of SpeedWarping works too, but I don’t know how to properly setup IK for it (this node is not working without foot IK). I don’t want to use solutions with closed source, because I want to know how they works and able to fix it in case of something is going wrong, and of course author of this solution may abandon support in any time. Does this plugin shipped with C++ source code?
