Ok, for some reason ZBrush has very weird Zooming behaviour and i dont know why. A year ago, i didnt have these problems: https://www.youtube.com/watch?v=itkYUxzgsPg https://youtu.be/V8OQGhRzS1E
probably something like that. Because of zbrushes "hunt and peck" design with twitchy sliders located in same space you have to drag to scroll, it is really easy to do stuff like that.
any model, or just this one? if only this one, might be related to scale of the model. Can add subtool of one of zbrushes standard models from lightbox to see if its really big or really tiny.
So i checked, its only in that project. No matter what mesh i import into that project, the same behaviour stays. I opened a new ZBrush project and there everything is fine. So it must be a setting that i falsely set or smth like that? Anyway, i just imported everything in a new project and now works. Very weird. Thanks…
