3D (3D Security)
9.x products change the default behavior with 9.5.1 because the dynamic nature of 3D provides the potential for it to be subject to security vulnerabilities. Several new changes have been implemented:
- 3D is disabled by default.
- The user interface has a new checkbox at Preferences > 3D and Multimedia > Enable 3D Content .
- 3D content has been integrated into the Trust Framework so that it's possible to display 3D content for trusted content even when 3D is disabled. You can trust files, folders, and hosts as privileged locations via Preferences > Security (Enhanced) > Privileged Locations panel so that when a PDF with 3D content opens:
- If it is trusted, the 3D content renders.
- If it is not trusted, a Yellow Message Bar appears which says "Some features have been disabled due to potential security risks. Only enable these features if you trust this document." The Options button provides the Trust Once and Trust Always options.
This preference category contains the following subfeature(s):
3D
