When viewing 3D PDFs in Acrobat X (both Reader and Pro) under OSX, it seems the OpenGL display does not display tranparencies.
On a PC this is fine, and when switching the Preferred Render option to Software it displays this, but without any shadows.
I have tried this on a number of macs in the office, with the same results. Viewing the same document in Acrobat 8 shows the tranparencies correctly (we have just migrated from 8 to X).
Apologies if this was a dupe issue - I trawled long and hard through the forums to see if anyone encountered the same issue.
I am running OSX version 10.6.8 and Acrobat X version 10.1.0
have you adjusted any of the setting in the preference panel as shown in the screen shot above.
And you have to remember that only certain Graphics cards are capable of 3D.
Thank you for your reply, Phillip.
Yes, we have looked at the settings in this panel. As mentioned above, we have changed the settings in Preferred Renderer to Software (from OpenGL)which causes transparency to work, but without shadows.
Using the same computer but running Acrobat 8 Pro works with OpenGL, and using other machines in the office (various forms of Macbook Pros, MacPros, iMacs, etc) also show the same issue - the lack of OpenGL render quality in Acrobat X vs Acrobat 8.
Doesn't seem to be a hardware issue, but am open to ideas.
I am not sure at all, but the only thing I have seen to have similar effects is the use of per-vertex colors.
BTW, a better place to ask such questions is Acrobat 3D Features forum.
Adobe people may ignore you there, but in some cases they accepted bug reports via that forum and fixed reported bugs.
