Okay, so I'm fairly new at zBrush. I have detailed pre-made things I've brought into the program but I'm taking the plunge with zSpheres now.
Something weird keeps happening when I'm creating and moving around my spheres. I'll be moving things around in the viewport (and this seems to happen when I have alt depressed and move things around) and suddenly my model/spheres will zoom (or scale) right out into a tiny area in the upper left corner of the canvas. I can't seem to find any reference anywhere to centreing objects or why this would happen when just moving objects anywhere.
Could anyone explain what I did and why it happened so I don't do it again? Since I can't seem to centre the viewport on the object I more or less have to start again.
