Quick ZSphere question

ZBrush Usage Questions
#1

Hello there, I am currently having a bit of difficulty with Z3s ZSperes. The problem is that the draw size of the brush automatically scales to the size of the sphere you are making. I liked to work in Z2 with draw size set to 1, and having to constantly resize the brush is doing my head in. All I want to know is, does this happen to everyone? and is there a button I can push to stop it?

Cheers everybody :slight_smile:

No joy?

If anyone comes up with a solution for this please let me know :wink:

#3

I find this annoying as well…

#4

Yes, me too. Also when turned on symmetry on X and Z for example you dont see the cursor snap on the ZSphere resp. the coursor vanishes. Occasionally it’s working but most times not.
Also I’m having problems with the zooming procedure with Alt+click-Alt+drag’ - the model jumps around on the screen. - This behavior is very annoying :-1:small_orange_diamond:-1:small_orange_diamond:-1:.
Also has anybody accomplished selecting, moving, scaling or deleting an attractor shpere yet? Dealing with ZSpheres in Z3 has become a nightmare :confused:

I presume you are all working with ZSpheres as a subtool? To get them to behave normally, simply switch on the Transp button in the Transform palette (Subtool Transparency).

#6

I am experiancing the same issues, when drawing zspheres the brush size doubles, I am wondering if this can cause zspheres to flip.

Any ideas?

#7

I did try some possible solutions like setting the alt brush to 1 instead of 2 but that does not fix, also its not a trasparency issue as mentioned above. Its essentially just sizing zpheres bruh to whatever the size of the las zsphere drwn is.

#8

Any other ideas??

#9

squeige,
I’m not fully understanding the problem you are having. Do you mean that when you try to draw a new zsphere the same size as the previous one - by holding down SHIFT as you draw - it is not sized correctly?

Thanks,

No … the issue is that the draw size updates after you’ve drawn a zsphere to the size of the sphere you just added. If you’re used to drawing with size 1 selected, this means you have to keep altering the brush size. Not a major issue if you’re working with similar sized zspheres, but a pain if drawing lots of varying sizes. Comparison between ZB2 and 3 below. After drawing a sphere in 2, the brush size stays at the originally selected size. In 3 it updates.

Moochie,
Thanks for explaining but I still can’t see the problem - unless ZSpheres in ZB3 are behaving differently for you than me. If I am drawing a new zsphere I click and drag to adjust the size, I don’t need to worry about the brush size at all as it has no effect.

#12

On zbrush 2 it was recommended that when drawing zspheres the brush size stay a constant 1, does this mean this is no longer a problem? I mean it was known to cause problems back then.

#13

Yes, it is no longer a problem. :slight_smile: Also, zspheres are rather better in ZBrush 3. :slight_smile: For example: if you draw a zsphere, drag to the size you want, then hold down Ctrl, you will be able to drag the new zsphere away from the previous one - you are in Move mode. Click Ctrl again and you will be able to Scale. Click again and you’ll be able to Rotate.

#14

Thanks that explains it all

#15

It’s not when drawing a sphere that the brush size matters, it’s when moving spheres. When switching to draw mode and back to move mode, the brush size changes and that’s where the problem is. I usually want to move only one ZSphere or ZSphere chain at a time, so I want the brush size to always be 1 when I’m editing ZSpheres. That’s the way it behaved in ZBrush 2, but not in 3.

I’m having this problem as well. :frowning: Every time I draw a new zsphere it resizes draw size as well.

I’m also having a problem with drawing symmetry. When I try to create with symmetry, it causes unusual behavior, creating a zsphere on only one side like the pic I’ve attached.

You can also see that drawing out the new zspheres resized my draw size, which may or may not be causing the problem.

Ah, the symmetry problem seems to be when I have more than one axis drawing symmetry at the same time (Z and X in the picture last post). I never had such a problem in Z2.

#18

Another problem: :confused:

I can’t access the Transform modifiers with zspheres anymore. They still seem to apply if I change them with another tool beforehand but I can’t changed them while editing zspheres.

#19

I seem able to modify attractor spheres but I can’t change them back into normal zspheres again by ALT clicking their stems. (I can’t even see where their stems are until I select the attractor sphere).

#20

Yes Marsyas ur right! Settings in the xyz-Modifiers (-the locking of the X Coord.f.eg. ) also seem not to have an effect on Polymeshes when doing some transpose technique like scaling or so…:confused:

reg. the handling of Attractor Spheres: According my experience somethimes the Attractor-spheres are neat but then out of the sudden theyre not. Also when doing Topology there was some similar strange behavior like a freeze of the mesh. It was not possible to move some microspheres any more. Hiting Ctrl+Z back to some prior state made the mesh working again. Also:always check your zMesh about symmetry. I experiencend some out of the blue z-model symmetry-loss (arms f.eg.). It feels like there is some kind of invisible masking on parts of the model or mesh activated. Maybe this happens occasionally when doing some keystrokes and mouse movement in combination (with a bigger brush size than 1) while zooming or so ? I hope this is all the (attractor)bug's about. HopeItHelps Happy ZBrushing Cheers kel .
