Move tool not... moving?(Nevermind, not resolved)

ZBrush Usage Questions
#1

Hi all.

I just created my very first zSphere model that I can actually do some low res moving on! YAY!

Anyways, I am running into a really weird problem. When I use the move tool, Draw Size 3, Focal -100, no matter the intensity, some vertices just refuse to move!

I don’t understand, the verts to the left and right of them will move, but these just won’t budge in any direction!

Usually when I feel I’ve done something stupid in ZB, I have, so please clue me in on what I’m doing.

Lemme know if posting pics would help, but my model doesn’t seem to be anything out of the ordinary.

Thanks for the help,
behemoth

EDIT: Thought increasing the draw size would help, and it did a little, but I still am having this issue. For instance, I’ll have x-symmetry on, and one of the points will move, the other will stay still.

I just don’t understand.

Although the Move brush acts differently to the move mode in ZBrush 2 I have not had any problems like you mention. Perhaps you have a mask applied and turned off mask viewing. You could try Ctrl + Shift + A to clear the mask.

Edit: Brush > CavityMask, BackfaceMask and/or ColorMask could also result in what you are experiencing.

Hmm, this is possible. It is 4 am here, and I am too tired to mess with this frustration right now (new at ZB, I’m sure you remember how it was :smiley: ). I will get back to you in the morning about this.

Thank you very much for the suggestion, this was driving me nuts.

Oh, and one more off the topic issue, with many of my zSpheres, I could not get them to rotate the way I wanted. Specifically, I could not get one to rotate around the X axis. Below the “zoom”, “scale”, “AAHalf” buttons on the right there are buttons which restrict rotation to certain axes, but there wasn’t one for X.

Is this built into ZB3? I am confused, and had to completely start over because without being able to rotate, there was unfixable creasing and folding in my adaptive skin.

The Rotate On ** switches you mention are for tool rotation only, in other words they only affect how you view the model not the models construction.

With your zsphere model in Edit mode enable Transform > Rotate and click drag on the zsphere links, not the zspheres themselves, this will give you free rotation. Holding ALT while click dragging will allow you to rotate about 180 degrees around the document z axis (facing you). Click dragging on the zspheres themselves will adjust the twist value, not the rotation as you want to (although the twist value is also a rotation in itself :slight_smile: ). An exception to this is the Root zsphere (the first zsphere you draw) which behaves differently in many aspects.

If you experience creasing in the resulting adaptive skin mesh you can adjust some of the adaptive skin settings before rotating/moving zspheres. Enabling Tool > Adaptive Skin > Mc and/or Mp (Minimal skin to Child/Parent) could help but is more likely that you will need to add some Membrane Curvature (Tool > Adaptive Skin > Mbr)

When you get more comfortable with Zspheres you may want to try a zplugin called ZSphere Tweaks which will allow you to adjust Twisting, Membrane Curvature and XYZ resolution on a per ZSphere basis. The Tool > Adaptive Skin settings apply to all Zspheres.

Hope that helps… and if it does not then try and get some shuteye :wink:

Okay, I really am getting frustrated now.

I have no masks on, draw size doesn’t affect it, and neither does focal shift.

some vertices just won’t move!

I have no idea what to do, and I am about to just throw my computer out the window. I am trying very hard to be patient, but I can’t even start delving into ZBrush if I can’t do something as simple as moving points.

Please, for the love of <insert deity of choice>, please help!
Thanks,
Eric

I suggest pressing unify in the deformation submenu of the tool palette. It may be that your model has grown larger than the maximum size that can be edited in zbrush 3.1 and that this is affecting your ability to move some verts.

Otherwise yes, pictures would help.
