Hello
i have a problem loading Metahuman Plugin for Maya 2024.
I installed the plug-in according the documentation, but Maya is unable to load.
I tried to set the system variables and deinstalled QuixelBridge, but it doesent work..

Please can you help here?

i am getting an error code in Scripteditor
// Error: file: C:/Program Files/Autodesk/Maya2024/scripts/others/pluginWin.mel line 316: Cannot determine the major version of library ‘dna’. Expected a ‘VersionInfo_getVersionString’ method or ‘version’ attribute.

Got the same thing on 2024. works like a charm on 2025.
I had used 3rd party plugins that used the metahuman dna calibration and it probably overwritten some manifest or maya config file(s). I traced the python code and the library file does indeed have a version number variable.

UPDATE: So, the library object in the plugin file was pointing to c:[username]\Documents\maya\modules\ and had some old Quixel file and a DNACalibration directory and just whacked them all and now the plugin loads in Maya 2024.

Hi guys,

i found a video on youtube how to solve this issue. It is quite simple… You need to deinstall your 3rd party DNA calibration tools + deinstall Quixel. These tools are making problems in combination with the new MH Plugin. After removing you should reinstall the MH Plugin 1.0 for URE 5.6 again, restart your PC and now it is working in Maya 2024..

You should have all these *mll unloaded in your Plug-In Maya Manager:
embededRL4
MayaUERBF…
PreviewRigLogic
DNACalibMaya

after unloading and deinstalling QB and 3rd Party DNA Calibration Tools and reinstall the Maya Plugin for Metahuman UE 5.6 >>> it works!

(for sure you need after restarting PC + Maya, again check the Plugin MetaHumanForMaya.py)

thanks a lot
