This product is available as Node Locked or Float License.
You don't need a license to open or use a scene using CustomControls, they are simply spline shapes.
Custom Controls will help you during Rigging, to create custom shapes for your animation controllers.
It will help creating animator friendly rigs with easily selectable and beautiful controls.
You can Create new splines and add them to your library, replace the existing objects with these custom shapes, change their size, orientation, and colors.
It only replaces the base object, so everything else like modifiers, animation controllers...etc stays untouched.
