@waylow , thx.
I am so sorry….. I am trying to understand the library override theory etc, but that will take some time :s.
The main problem for me is that I cannot set the rig to FK/IK using the ‘switch’ you mentioned/showed in the dropbox video,
sliding it between 0 and 1 value.
When I do try, it mentions: “Disabled. Can’t edit this property from an override data-block”,
as shown in my second picture.
I am trying to find a solution, but at this moment its difficult for me to understand all of it.
