Genesis 9 FACS – How do you drive hundreds of DAZ morphs with a 2-D facial board in Blender?

Setup

  • Blender 4.1 (Win11)

  • Diffeomorphic dev 4.4 + MHX RTS 4.4

  • Genesis 9 figure imported with JCMs + FACS + Head (no Face Units).

  • Converted to MHX. All sliders work; JCMs bend nicely; FACS react in DAZ > Morphs.

What I’m missing
Scrolling through 300 + morph sliders is painful.
I’d rather have a 2-D facial control board (eyebrow row, eye row, mouth row, etc.) or at least a compact multi-column GUI—similar to what Faceit or ARP-Face shows in their demos, but linked to the existing DAZ FACS/JCM shape-keys, not regenerated poses.
I'm looking for something like Metahuman Rig.

My questions

  1. Has anyone successfully driven DAZ Genesis 9 FACS (or Expression) morphs through a 2-D board—Faceit, ARP-Face, Rigify-Face, or a home-made widget rig?

  2. If yes, what workflow did you follow to map the board controls back to the existing shape-keys (drivers, scripts, add-ons)?

  3. Are there open-source templates or scripts that already pair the 63 AU names to common boards?

  4. In your experience, does baking corrective JCMs (Baked Correctives ON) affect any driver linkage?

Thanks a lot!

    With diffeomorphic Thomas fixed the G81 face controls to work with G8 G9 as well, so you just apply the G81 face controls to G9 in daz studio, then export to blender. Actually there's a minor issue because the face controls are in a bad position once imported in blender, it's easy to fix this in edit mode, now reported to Thomas.

    steps:

    1. in daz studio apply the G81 face controls to G9
    2. export as dbz
    3. in blender easy import with FACS, the face controls will work on G9

    update. Now fixed in the last commit.

    Thanks, Padone.

    Sound great!
    Is this the plugin you mentioned ( G81 face controls)?

    No, it's the standard face controls you get with the base G81 package.

    Thanks a ton for the tip!
    I was this close to buying that add‑on, haha.

    I just tested your method in Blender and it worked perfectly.
    From here I’d like to fine‑tune the rig to suit my own workflow, so I’ll dig in and customize it myself.

    Really appreciate you saving me both money and time—cheers!

    Just to clarify. That 2D control board your talking about is actually just a rig. It can be done but I don't think anyone actually does it because you can import expressions and what not from daz already. However there's nothing actually stopping someone from building a facial control rig like that. You should be able to find tutorials about it on YouTube pretty easily to learn the concepts.

    Yea, I will use the Daz morph. But I also want to use 2D facial controller to  intuitivelly tweak those parameters.

    Thanks for the advice.
