Reply To: Arm FK Rotation.
@waylow, Thank you!, the updated Vonnbot rig 3.0 and python ui_script work good.
Now I can effectively use the FK arm rotation, and adjust the settings/slide bars in properties.
Master Wayne, I just had a few issues:
1. Had to reassign the camera´s to the library overriden Rig: set a new Child Of constraint and target my rig Rivet_rig.001 and its torso bone, only then the camera´s would follow my Rivet character.
2. The Viewport Gizmo: only Scale is visible when selecting an item. Deactivating the Active Tools option in Viewport Gizmo makes the Gizmos invisible in the viewport, as it should, but Activating the Active Tools option makes the Scale Gizmo visible, even when I have the Scale Gizmo deactivated. Move and Rotate Gizmos don´t show up in the viewport when I activate them.
I took a screenshot:
