Can't change focal length of perspective camera

ZBrush Usage Questions
#1

After working on a model ( xyz scale of 2 ) for a while, the focal length slider of the camera just stops working without any apparent reason.
Universal camera on or off does not matter. I can still switch between perspective and ortho mode, but the focal length won’t change any longer. What am I missing ?

Hello @zzeebee ,

Is the Auto-Crop icon next to the quicksave button active? If this is the case, then Auto Crop mode is active, and the perspective will no longer update.

Good luck!

Hi Spyndel,

Yes, AC is active, maybe because in fact I do have a large, rather flat model with that large bounding sphere. Any way to switch AC off or work around the issue somehow ?
