Hello, I’m having an issue with zbrush and I’m hoping there’s a solution. When holding down the shift key and moving the cursor over the mesh (without pressing down) the viewport camera jumps to what seems like a random position and rotation. This is extremely annoying when i want to use the alternate brush to smooth/polish and the camera jumps everywhere. Is this a feature I can turn off or is it a bug?
any info is greatly appreciated,
thanks!
Are you using a tablet? It’s possible that your pen sensitivity is set a little too high and telling ZBrush that you’re dragging on the canvas. Shift+canvas drag tells ZBrush to try and snap the orientation to the nearest axis.
no this is entirely different. try it yourself, with a pen tablet hold shift and hover dont drag your pen across a mesh in edit mode eventually your camera view will wig out to a random rotation. This doesn’t seem like an intentional feature. I only noticed this because i’m using the Hpolish brush as my secondary and i’m doing lots of faceting with it. So for the most part i’m holding down shift, but my pen isn’t always being pressed down on the mesh. sometimes i inadvertently hover the cursor over the mesh with shift held down and occasionally the camera goes bonkers. Again just to clarify i’m completely zoomed into the mesh and I’m definately not shift clicking outside of the mesh to snap it to an ortho view.
Do you have “Right Click Navigation” enabled in ‘Preferences > Interface’ by any chance. If you have that enabled and a “right click” function assigned to your pens side switch, then you might be accidentally hitting the side switch every once in a while.
Actually, now that you’ve described things more I can see that you’re accidentally invoking a feature called Mouse Gestures.
SHIFT + circle with the mouse = frames the ztool
SHIFT + several vertical movement = zoom in
SHIFT + several horizontal movement = rotate
The problem is that you weren’t aware of this and so were making it happen by accident. But if you are aware of it you can use it to save yourself quite a bit of effort while you work!
AWESOME!! Thanks! Now I know why this is happening.
Is there a way to disable this feature by any chance?
no afaik and it’s so much annoying even if you know about the gestures.
Moving the pen few times above the tablet before touch down is a natural thing to do (at least for me) 
is this absolutely true? there’s no way of disabling it? In a way, this is just as annoying as the windows 7 pen flicks feature. Just a simple toggle switch would be awesome, as i can see it being useful when you’re not working on the details and you’re not constantly using your secondary brush. but when you are zoomed up on a model and you are using your secondary brush quite heavily, the last thing i want is to accidentally rotate the model. Just a simple toggle please

Hey guys!
I’m not sure this can really fix the problem since I only tested it for a few time (it might create other problems as well) but I set the click distance to 1 in the Interface menu of the Preferences and so far, it seem to help for me. :eek:
I too am experiencing this problem of invoking Mouse gestures when using the smooth brush. It’s quite disruptive.
Adjusting the click distance as suggested by amnesiak unfortunately doesn’t solve the issue for me.
Any fresh ideas on a workaround?
FYI Marcus_civis just confirmed on another thread that the feature can’t currently be disabled

After googling for this problem, I ran across this thread and saw that it’s actually a feature.
It’s a nice feature, don’t get me wrong, but it REALLY needs a way to be disabled. Or at least not to be on by default.
This “feature” drives me absolutely crazy, for the longest time I didn’t know what was causing the issue and though it was something wrong with my wacom pen or tablet and was going to buy a new one. There seriously needs to be a way to turn this off.
At its current state it’s hardly any use cause it’s so hard to control. Sometimes it causes my model to vanish from my screen completely and i have to hit ‘F’ to bring it back. perhaps you could have it bound to CTRL rather then my smooth button(which I use constantly).
I’m also a programmer and I know fixing this is as simple as adding 1 more toggleable button and having an if statement like:
if (!mouseGesture.isEnabled())
return;
Please, please, please, please have your programmers take the 1-5 mins to add a toggle before the next update.
I submitted a ticket to their support section, will see what happens.
I have the same problem
It is hugely intrusive to my work flow. I know there are trying to be helpful but this does not work at all well. please switch it off!!!
I often move the brush over the surface to remind myself of the contours and this “feature” reads this wrong every other time.
I agree with everyone’s frustration here. I often go over my stroke “in practice” before applying and this new feature completely distrupts that workflow for me. Please add a feature to disable! Thanks.

Yay! Fixed in ZBrush 4R2… Preferences>Edit>Enable Gestures (it’s off by default)
Can’t tell you how pleased this makes me
This viewport jumping issue when rotating the view, etc. using the right click on the stylus have been going on for so long that I installed Blender and I’ve been sculpting with Blender since then. Works great.
Left click rotation (tip of the pen) works fine, it’s only the stylus(es) right click that ends up most rotations with random results
