Support for Space Navigator 3D Mouse?

Oh, that did actually fix it. Was just about to post the issue from the log

Works fine now, thanks! Good work too. Only issue for me is the way I usually used the mouse in 3D apps is by having it rotate around selected objects. That would be a nice feature for sure. Like what ALT-Mouse drag does I guess. Other than that it feels a bit slow, especially rotation but that’s just preference obviously.

Also trying to integrate into the engine source, getting compilation errors that si.h in SpaceNav3DPrivatePCH.h is missing even though I do have the libraries in the correct third party folder it seems. Surely something basic I’m missing.
