@andreanjos Well, I am around. CollieMouse is still active (as I am using it myself daily) but I have not got around porting it to R20 yet. I am bound to step into R20 development soon though.
CollieMouse is an alternative controller however. It does not work through the abovementioned dialog but comes with its own dialogs. It does support the navigation cross and the newest 3Dconnexion functionalities.
I have not officially offered CollieMouse again since only very few C4D users seem to utilize a SpaceMouse at all (personally, I find it indispensable) and there is an unsolved issue in the screen refresh, but I can still provide the plugin when there is interest.
