MetaHuman for Maya 1.3.3 blocked by Windows 11 Smart App Control

Development Getting Started & Setup
, ,
1

Hello there!

I am experiencing an installation/loading issue with MetaHuman for Maya 1.3.3.

My configuration:

  • Windows 11
  • Autodesk Maya 2026
  • Unreal Engine 5.8
  • MetaHuman for Maya 1.3.3, downloaded from the official Fab Library.

Problem:

Windows Smart App Control blocks the following components:

  • _py3rdf6_5_8.pyd
  • MayaUERBFPlugin.mll

The Windows Code Integrity log reports that these files do not meet the required signing level.

Both files have been verified using SHA-256 and their hashes exactly match the files contained in the original Epic ZIP archive.

Maya consequently reports:

  • dnacalib2: expected 5.1.6, found N/A
  • rdf: expected 6.5.8, found N/A

Could you please confirm whether MetaHuman for Maya 1.3.3 is compatible with Windows 11 Smart App Control?

Is there an officially signed or otherwise compatible build available for Maya 2026?

Thank you in advance!!
