AW: Exported using aw078 (on DEV300 m64) and there are no black rectangles as in
the attachment, so the error is not a wrong export, but just the Dialog
informing the user that transparencies were solved (???).

When the user adds a 3D shape he adds a transparent object. Before AA it was
more in the sense of a 'masked' object since the BitmapEx with the rendered 3D
scene (as long as no transparent 3D objects were used) was more a mask. With
AntiAliasing, it HAS to be a really transparent object, since the AntiLiasing
between 3D object bounds and the background can only be done by using an
AlphaMask in the used BitmapEx. I do not think that AntiAliasing should be
removed again to solve this (even then the problem occurs when using transparent
3D objects).

Thus: When the user adds 3D shapes, he adds a transparent object.

This is not different for charts. They may create their own background, but
that's a 2D object behind the 3D scene. Latest when a transparent 3D obect s
used in a 3D chart the problem will reoccur.

So, what should be done here at all ?!?
