    Love the presentation, the way I incorporate them both in my workflow is like this. Fk is used for everything up until I want them to not move for example if I have a character walk up to a trash I switch my arms into IK once they grab onto it so when I move my character around my arms will be stationary as if it’s actually holding the garbage can still.
