Hi guy’s,
I recently switch from 3ds max and i was a bit frustrated about how my space navigator was acting a bit erratically when zooming or panning so i went in the NDOF menu and adjust the settings as bellow and now it’s as smooth as silk for navigation ;
Just focus on the 3 top settings since the rest is personal setup for axis
Sensitivity and orbit sensitivity are up to your personal choice but the third one Deadzone was obscure a bit but it was the one that fix the erratic zooming and panning for me.
At default it was 0.100 and at 0.010 it work like a charm for me.
I hope this will help people having problem with space navigator in Blender!
