I’m a traditional clay sculptor and am used to having my sculpture on a turntable in front of me. I’m continually frustrated with the rotate view in zbrush moving my model off the horizontal. I’m currently using zspheres and the rotate axis seems to be linked to the orientation of the sphere I currently have selected. Is there any way of setting a vertical rotate axis for the whole model so that turning it in y rotate mode actually keeps it level?
So there is no real time fixed y rotation?
If you follow the link I copied above you will see that Marcus Civis made a neat little plug in called YaxisRotate. You can download it from that page. Follow down to his thread to about the 8th entry where he provides the plug in download zip file.
