Hi guys…
I just started working with Zbrush and love it… However… I think I’m making a very basic mistake that I can’t solve for some reason… I’ve allready spend hours trying to find out what I’m doing wrong, but with no luck…
Here’s the thing…In my first try I made a face using the DynaMesh128.zpr as a base from je lightbox projects… I appended a subtool for the eyes and mirrored and welded this so I got two eyes… Fantastic! 
Now I want to make a more complete character so I decided to use the zsphere technique… I followed the lesson and made base shape and converted it so that I can sculpt on it… When I got to the eyes… I again appended a subtool… choosing the Sphere3D again, but for some reason it won’t mirror and weld. It keeps on saying “the resulting 3D mesh does not contain polygons. operation cancelled.” It’s making me craaazy…
HELP!
What Am I doing wrong??? It only happens when I start with a base that’s originally been made out of Zspheres…
Ik really hope you can help…
Thank you in advance!
