Hi, Paride. You are right, it works with Octane Cameras...
I never use Octane Cameras : in the old times, it was just a target camera and I don't like to use 3Dconnexion with target cameras.
Now there is an option to have a free camera, but as Octane Cameras seems to be defined as objects ( and not cameras ) I can't use 3Dconnexion mouse...
