Fixing and adjusting symmetry/pivot

ZBrush Usage Questions
#1

Hello, I am looking for a guide or tutorial on how I can fix/adjust the symmetry/pivot to an object.
Once i insert a Sphere and then move/rotate/scale it to how i want it… I would like to be able to continue sculpting in symmetry but the pivot remains where it originated from. I have seen alot of tutorials that kind of talk about it but havent found one that specifically answers my question.

For example: I am working on sculpting a skull but i want to have the bottom jaw as a separate subtool, so once i finished the top part of the skull and i insert a sphere and reposition it below the top part of the skull, I want to be able to work on the jaw in symmetry.

Thank you.

Short answer, if you don’t reposition the tool away from where it is (0,0,0), symmetry should be fine.

Very easy and handy improve in Zbrush lately. Go to Geometry-> Position Move sliders in your Symetry axis

#4

You can use Set Pivot and Clear Pivot in the Transform palette to temporarily set the pivot for a subtool or mesh portion.

I tried this, it allows me to move the object but the pivot doesnt move with it accurately, i have zBrush 4r6. Once moving the object and activate symmetry, the symmetry point is still in space and not on the other side of the object.

if this can help as a work around. making parts invisible allows symmetry for what is visible.

#7

yes but then i cannot work on the jaw subtool accurately if its position changes relative to the rest of the skull subtool

#8

Do you have the axis plug? You shouldn’t be having problems, jaw is below skull but still centered on x, if transform axis is set to x with symmetry enabled what is done to left is mirrored to right side.

UPDATE: I was able to activate symmetry on the moved sphere subtool by turning on Local Symmetry, however since the skull subtool was rotated, the sphere object has the symmetry facing a different direction. Rotating the sphere does not change the orientation of the symmetry along with the rotation, is there a way to possibly adjust that? for now i will rotate the skull subtool to match the sphere and then rotate it back… however I am hoping a more efficient way to do it in the future.

Transform pallette…see link in post #2

I dont know what the axis plus is. I modeled the skull first, moved and rotated it where i wanted it and inserted the sphere subtool and moved it under the skull to prepare the jaw modeling.

You probably didn’t ‘move it’, you moved it around in front of the camera.
This may be helpful to you(it sure was for me)
