Hello,
I’ve been using ZBrush for a while now, but this is my first post on ZBrush Central.
I have this model of a capital that has 4 identical sides and each side had 2 symmetrical sides. I was wondering if it’s possible to set up symmetry in ZBrush in a way that I can sculpt only on 1/8th of the model and the rest is covered by symmetry? I’ve tried few different configurations, but none of them work completely. I have attached images of the model.
Thanks for your help!

Having both X and Y mirror symmetry on should work.
Thanks Marcus for reply!
I’ve already tried that option. But I end up with only half of the model covered. I have attached diagram. If I enable X symmetry I cover area in red, if I enable Y symmetry I cover green area in addition, but still I have half of the model not covered. Sure, I could do the sculpt again on the other half, but feels like waste of time on doing same thing again.
What I meant is that you can have the two axes active at the same time. See my picture, though note that I have X and Z active because of the way the model is oriented.
Marcus, I absolutely understand what you mean - I’ve tried that, but in that case I’m still missing one mirroring. If I would draw a stroke it will follow green arrows, but I need also additional symmetry following red arrows. In total I should have 8 brush points, 2 on each of the 4 corners (using X+Z sym I still get only 4 points). Does that make sense? I don’t know, maybe I’m asking impossible 
why not just sculpt one quarter or half and then use the mirror and weld function?
have you tried the radial symmetry setting as well?
Thanks Spaceboy, I think Mirror and Weld is the way to do it.
If I turn on Radial Symmetry - that’s what I get (every second point should move opposite direction instead of all of them going same way):
The workaround is to first sculpt with XY Symmetry on so I get this:
Then rotate model 45 deg and apply Mirror and Weld to get the final result:
Thanks a lot for help, I think that’s the method I will go for.
I understand better now. Yes, as spaceboy says, Mirror And Weld is the way to go. I don’t think there’s another way to do what you want.
An addition to this method would be sculpting a mesh with the XY Symmetry and adding an Array to that subtool that is rotated 90 degrees. Its the same result, except you can see how the edges are lining up while you’re sculpting
Is there any reason why mirror and radial symmetry cannot both work at the same time? I wanted to sculpt a tower that’s identical on all four sides, but I cannot. I tried to have Y symmetry turned on and Radial with a count of 4, but it won’t work. Seems like a Zbrush bug or limitation.
Oh, yeah guys
But, what if I need tot 4 radial symmetpy elements, but 3?
3 symmetrical elements meeting three times along the working radial radius
Yes, this topic is already seven years old. And radial symmetry still looks wretched and underappreciated ignored.
Yes, I got the same expression.
It would be soo much easier, to have a flexible solution to model symmetrical with radial symmetry at the same time. I run in exactly the same problem.
Mirror & weld would not help me here. Because there are always some unsymmetrical parts, which should be avoid mirroring.
In this example, just the poly right beside the already sticked out one, should qmeshed the same way.
The array operation is already done and applied. So it´s connected and I can´t use it.
In my eyes, it should somehow manageable, like Autodesk Sketchbook can do.
May I am wrong, and ZB is limited hier.
Bumping this ancient thread again. It’s the current year and there still doesn’t seem to be a way to do radial symmetry with mirroring(!?)
I ran into this problem while trying to make a mandala pattern on a plane. I ended up just drawing the pattern in Affinity Photo, exporting it and using it as an alpha in ZBrush.
