The new webcam face tracking and audio to face for Metahumans is great, but if you want it to work with your already set up custom characters with the standard ARKit 52 Shapes it won’t work out of the box. If you are using Morph Targets or Pose Assets with the 52 Shapes naming scheme you can just rename them to this new list and it should start working! Have fun and please show your results if this helps!

Edits Made… Fixed Typos and mixed Order of Left Eye
Thank you to @CSKISS for pointing them out!
Thank you very much for sharing this list!
I was struggling with the mouth parts on my own, wondering if anyone else was looking for these —then I found your post. It was a huge time saver! Thanks again for putting this together.
I’ve also created a tutorial on this topic, which will be released in a few hours. I’ll share the link here once it’s available.
In the video description, you’ll find a TXT file that people can download (it contains the corrected, complete list for simple copy-paste).
Below, I’m also sharing the full corrected list without comments for convenience.
Issues I Found (Mostly Typos)
I’m listing the corrections here in case you or anyone else is interested:
Thanks for the corrections! This was made later in the day and I was exhausted, I came back to it recently and notice some weird stuff with eye movements. So thank you for catching some mistakes. Made the edits and gave you credit! Looking forward to seeing the tutorial!
I wanted to automate this process, but as I mentioned in the video, it’s all quite time consuming.
What I think would be the easiest solution is some sort of Python script that automatically renames the selected animation asset curves to match the ARKit names. I tried working on this, but I kept running into brick walls, so eventually I gave up on it.
Anyway, here is the full tutorial, in case you or anyone else is interested, It covers the workflow between Unreal and Blender as well.(and also shows how to get head movement working if anyone wants to set that up.)
