I am a long time user of Zbrush and Sculptris. I have been trying to figure out for the longest time why when I release Alt after panning does my model snap or pop somewhere across the canvas. In Sculprtis it works perfectly where I can pan, then release alt and go on zooming, but in Zbrush When I release alt every time my model flies off somewhere random and zooms out or in. Is there a way to fix this? I would like to be able to use alt and not just ctrl-right click to zoom.
I think there’s a setting inside ZBrush.
