Mudbox camera not rotating. Can still pan and zoom

[Anonymous]

So I've searched the forums and found no answer to this so far. Basically, I can't rotate around my model in Mudbox using ALT+LMB or any other way. I've reset all the cameras and made sure that the rotation isn't locked, restarted Mudbox etc. I can still pan over it using ALT+MMB and zoom in and out with ALT+RMB but just can't rotate at all.

You may have inadvertently changed the hotkey. Easiest thing to do would be to delete your prefs: https://knowledge.autodesk.com/support/mudbox/troubleshooting/caas/sfdcarticles/sfdcarticles/Reset-M...

are you in perspective mode? possible the rotation is locked in the camera settings. try looking into there
