Converting Procedural Animation to FK
You can convert from Procedural Animation motors to plain old FK ( aka basic animated knots/splines ) via the Convert to FK function on every Bone Motor. This allows you to easily generate procedural animation, then bake them out to regular old school animation knots/splines for further manual hand tweaking.
How to convert to FK
First, select the bone motor ( either by selecting the bone and clicking on the motor type button or directly selecting the bone motor in the scene browser panel )
Select an option to either to convert just that motor or all motors in the character to FK
An option will show up asking you the resolution ( value 1 to 100 ) you want the converted FK knots/splines to be. Select something like 50 to 70 for a reduced knots/spline representation
The motor should now be removed and a new FK Motor with converted knots/splines will be installed:
