Message: This document contains overlapping transparent objects
Cause
The document you are exporting contains transparent objects on top of one another. Exporting transparent objects to a CMX file when there are more than three transparent objects in a stack is likely to cause problems for other programs.
What Can I Do?
To limit the transparency
to the lower three objects and export the other objects solid, click Limit.
To continue exporting and
include all the transparent objects, click Continue.
This may cause problems when you import the file into other programs.
