Shrinking mesh when exporting from zBrush

ZBrush Usage Questions

Hi all

I have this issue for quite a while and I haven’t figured out how to solve it.


  1. I export as an obj a simple sphere from Maya. Scale is 1, xyz are 0.
  2. Import it in zBrush. No point of storing morph target as I intend to use it as a blendShape back in Maya
  3. Divide it few times, push some geometry around.
  4. Go back to sDiv 1 and export the result. My export scale is 1, xyz offsets are 0.

When I import it back in Maya, I discover my whole sphere has been shrunk. Not to much, only by an annoying tiny bit.
This is the sphere playblast http://balaurian.ro/tmp/sphere.gif

Does anyone know how to solve this issue? Am I doing something wrong? It’s extremely annoying when one has to do blendshapes. Or when you do modeling and have to go back and forth Maya/zBrush.

Should I just work on the first subdivision level, without further subdivide the mesh?

Thanks!
