Metahuman Expression Editor export

Hi. I have a character exported into Maya 2024 from Unreal 5.6 for animation work. I have now updated this asset using the new expression editor, but as far as I can see there are no export pathways that allow me to update my original UE export assembly. Switching in the new DNA for a new assembly gives a compatibility warning. Can you give me any pointers?

UPDATE: I found a way to ‘export’ by simply saving the expression edit scene with the preview and edit grps deleted. This works in the rig, but I see that the ‘rl4Embedded’ node is replaced by a MetaHumanDNACalib node. Is this an updated way to hold the data or something designed only for use in edit?

Ok, dug into the docs and found the solution is to cycle the DNA through the MH creator in UE and re-export to DCC. This can be closed.
