Summary

I’ve been developing a custom metahuman in Maya 2023 using Metapipe. I open up an existing Maya file that contains the (working) metahuman and save a new version. Even without making any changes to the file, just saving as a new version, the blend shapes do not get activated by the face board controls in the new version.

Steps to Reproduce

Save new version of Maya file with Metahuman, reopen new instance of new file.

Expected Result

Blend shapes to correctly activate in response to faceboard controls in version save.

Observed Result

I’ve tracked the disconnect down to the embeddedNodeRL4 node. All of the inputs and outputs are still connected in the node editor, and the path to the DNA file is correct. The metahuman’s face joints translate correctly, it’s just the ‘Bs Outputs’ attributes that are not activating in the RL4 node.
Is there a way to reconnect the RL4 node’s inputs into its outputs? Is there an issue with a way that I am saving the file?

Platform(s)

Maya 2023

Additional Notes

Any help would be greatly appreciated. I have animators in Maya that need the blend shapes to display properly so they can accurately match the performance reference.

Our lead TD found that having the DNA saved to a local drive, rather than a network drive, has helped with this issue. But after saving a few more iterations the connections between the RL4 node’s input’s and bsOptuputs broke again. We’d still be interested if there is any other advice or explanation as to why this error occurred.

im running into the exact same issue and its quite infuriating. Any update on this?
Did you ind a solution?

Eventually we just got lucky and some files began to save consistently.

Though I’m now experiencing this issue on another metahuman that was generated through metapipe. But this time the blend shapes respond correctly to the control inputs but the joint transforms remain static and unresponsive, the opposite of the problem I had before. Dna is pathed appropriately and rl plugins are the latest versions and everything.

I feel like I’m losing my mind.

Do any epic devs out there have a secret dna calibration or dna editor script that could fix this?
