The plugin that supports PoseDriverConnect within Maya is out of date for the current version of Maya. This means that those of us using Maya 2025 cannot work with the system and export to the Unreal as in previous versions. Please could you compile the MayaUERBFPlugin for Maya 2025?
My friend who is a game dev reached out to Epic Games and apparently they compiled a 2025 version. Here is the update.
I would try and upload it here but Unreal is not letting me because I am a new user
But try contacting unreal directly and see if they can send you the updated one!
Mine seems to be working, however I am getting this error
import pipe.m.wrangler; pipe.m.wrangler.run()
Warning: Unknown object type: UE4RBFSolverNode
Error: EpicGames.PoseWrangler : Unable to import API v2, falling back to API v1 - No module named ‘six’
Which I worry is somehow causing maya to be really slow.
So I would say, ask Epic Games directly for the latest version (or try redownloading it from the store, they might have already updated it) and if you can get it working let me know if you get the same error!
If you do get the same error and know how to fix it, I would greatly appreciated knowing how you did!
Best of luck.
