I’ve update mGear from 3.6.0 to 3.7.8 and it looks that RBF Manager doesn’t create new nodes. I tested in my main scene started in version mGear 3.6.0, also tested in a new sceen, where created rig from Biped Template, the result was the same, when I press New RBF nothing happens in the viewport, but in the script editor I recive something like this:
select -r arm_L0_fk0_ctl ;
