ARKit Eye Movement and G8.1 and G9 Eyelashes (No Morphs/Shape Keys)

Hi! This is my first post so hopefully I can explain this properly.

My pipeline is to use face mocap which includes eye movement which ARKit supports. I am exporting G8.1 and/or G9 characters with the ARKit shape keys into Blender. The eyelashes and the eyeballs do not have the eye movement morphs that the main character mesh has. So the character will have eyeLookDownLeft, Right, etc. but the eyelashes do not have these morphs. The eyelashes have eyeBlinkLeft/Right, eyeSquintLeft/Right and eyeWideLeft/Right but none of the *Look* shapes/morphs.

Is this normal or am I missing a step when exporting or setting up my Daz character?

They eyeballs are also missing these shape keys but they are super easy to create. The eyelashes are a real pain to do for the look morphs/shapes.

    Those are not morphs, theya re conrtollers driving the bones - so it sounds like an issue with the lashes not picking up the posing information from the base figure.

    The daz FACS morphs are compatible with ARKit you don't have to do anything, that's indeed what FACS is for. With diffeomorphic just import a figure with FACS and you'll be able to load ARKit mocaps via the retarget module.

    I'm still so confused. In Blender, the eye movement is using a driver to change a shape key that tells the shape key/morph to activate when the eye is in a certain position. This btw is totally broken for G8.1 as the z rotation does nothing and the x rotation drives eye look left and right (which is incorrect).  Putting that aside for now, the bigger issue is that there is no "look" morphs on the eyelashes so the eyelashes do not morph when the eye looks around triggering the look morphs on the eyelids.

    Does that make sense? I've tried several characters. G9 works best (seems to work correctly but I have not tested extensively). G8 seems to have no ARKit shapes or morphs and G8.1 has everything but it just doesn't work and does not export with eyelash morphs/shape keys.

    Oh.. I should state that this is all working in Daz3D. It's just not exporting the morphs on the eyelashes it seems. If the morphs were there, I could just setup the drivers myself.

    So Difeomorphic is another Blender Add-On! I understand now. Let me work on that tomorrow and see if I can figure it out. :)

    Yeah so I've been using Daz to Blender Bridge which is where the eyelashes are broken (not sure how to submit that issue to the developers). The Diffeomorphic thing seems to work but I can't figure out where the plugin for Daz is that exports to Blender with the proper body shapes. I'm still working on it. If I could just append the eyelashes with the correct shape keys, I'd be happy (even though it's a pita). I really wish the devs would fix it... or maybe I can have ChatGPT look at the code.

    There's a wiki manual with everything explained. Basically you use a daz script to export the dbz, then easy import in blender selecting the features you want.
