Mirroring across multiple axes

Help!

So I’m modeling this Corinthian Column Capital for a client using Maya and ZBrush, based upon the attached images. I modeled a rough version of each piece in Maya, then combined them to one solid mesh.

The model’s geometry is way more complicated than just an X & Z axis symmetry. There are 8 of each leaflet, each row offset by 22.5 degrees, and 4 each of two types of scrolls, offset by 45 degres. Detailing one section in Zbrush, then attempting to get it back into Maya and connect it to another is not working. I’d like to keep it to one mesh since it’s “carved out of stone.”

I either need to find a way to create a custom axis at 45 and 135 degrees to mirror across in addition to the regular x&z, or find another way around my problem. Is there a way to create offset instances of the model in Zbrush? Any other suggestions? Please help!

Thanks - Kelly

I don’t know if this would work, but it’s worth a try:


  1. Create the cube shape that you need and subdivide it to the level where you’ll be adding the details.
  2. Go to level 1 and create two layers.
  3. Append a cylinder to the model, sized and positioned to be a close match for the cube.
  4. Use ProjectAll to turn your cube into a cylinder. You can now delete the cylinder subtool.
  5. On the cube, select your other layer. Go to the highest level and using radial symmetry with a count of 8 sculpt the details that you want. Because it’s a cylinder, the details will be perfectly mirrored.
  6. Go back to level 1 and switch to the first layer. Turn it off. With luck, the sculpted details will move to be positioned right on the cube.
In effect, we’re basically using a pose layer. It’s just that the pose is more morph target than anything else. :slight_smile: Like I said, I don’t know if it will actually work. But it’s worth a try.

Looks like my best bet is to use radial symmetry for the y axis as well as rotate and smart symmetry options from the deformation settings in the tools panel. Thanks for putting me on the right path!

for anyone who stumbles across this old post of mine and cares:
I solved my problem by using different combinations of the deform palette and smart ReSym. It actually worked out really well, here’s the finished product:

Beautiful results!

Yeah, that’s a capital capital! :slight_smile:

That looks really good. A little tutorial or WIP images will be be greatly appreciated. the render and material are fantastic.

For future reference, the ZProject Brush is also a good way to transfer detail.
