Well, about 3dconnexion spacepilot, the one that i have, I was thinking like you before I try it, but's is only personal opinion and workflow.
why in the same company, you have 3 softwares and 2 of them have the option to control that 3dmouse?
hexagon and dazstudio have the option,
and only carrara doesn't, that's sad............
well, I am here in this forum is because i am learning carrara, and i like it.
