The dynamic nature of 3D provides the potential for it to be subject to security vulnerabilities. Therefore, the autoplay of 3D content in PDFs is disabled by default.

Enable playing of 3D content in PDF

When you open a PDF with 3D content, you see a yellow bar at the top with the message - "3D content has been disabled. Enable this features if you trust this document."

Autoplay of 3D content is disabled by default

To enable 3D content in the current document:

Click the Options button and then select an appropriate option:

  • Trust this document one time only
  • Trust this document always

To enable 3D content permanently:

  • Go to Edit > Preferences > 3D & Multimedia and then select the Enable playing 3D content checkbox.

Enable 3D content for trusted 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. The feature works as follows:

  • Disable 3D content.
  • Trust files, folders, and hosts as privileged locations via Edit > Preferences > Security (Enhanced) > Privileged Locations panel.
  • When a PDF with 3D content opens:
    • If the file/location is present in the Privileged Locations, then the 3D content renders.

If it is not trusted, a Yellow Message Bar appears that says “3D content has been disabled. Enable this features if you trust this document.” The Options button provides the Trust this document one time only and Trust this document always options for the current document.

Specific configuration for enterprise IT

Enterprise IT can configure the end-user settings via HKCU\Software\Adobe\Acrobat Reader\<version>\3D\bEnable3DContent. Enterprise IT can disable and lock 3D rendering so that the user cannot change the setting via HKLM\SOFTWARE\Policies\Adobe\(product name)\(version)\FeatureLockDown\bEnable3D.
