Our the new free Modeler tool ToggleCC has been released and is available to download on our website http://www.trueart.eu (http://www.trueart.eu/)
ToggleCC is toggling back and forth between regular polygon and Catmull-Clark sub-patch (regardless of Sub-D Type settings). After assigning to hot-key you won't need anymore to change Sub-D Type again ever. Going between Sub-Patch geometry to CC will take just one key press. Going back to Sub-Patch - TAB press.
