Hi. So today I opened up max and drew a zsphere on the viewport. I pressed shift+click and created a second Zsphere. Now I press A to preview and all I see is the mesh for the second zsphere. The initial zsphere is not visible… I’m trying everything but it’s not turning visible. It’s just an open mesh extending to the second zsphere. Anyone had this problem before
“So today I opened up max and drew a zsphere on the viewport”
Do you mean max or Zbrush? 
However, what you´ve just discovered is the Root Zsphere…
Aaarhg I can´t explain it with my poor english.
Please see here (Post no.2) :
Yikes… I’m such a noob… I’ve been using zspheres for a few weeks now and it never occurred to me that this is why two extra zspheres are placed at the beginning :o
Thanks!
