It is crazy opaque on what kinds of asset pipelines can support "Geometry Morphers" in scenekit. Answers to any of these questions would help me greatly.
- DAE does support morphing (albeit super inefficiently regarding file size), but which exporters, conversion tools, or DCC software "just work" with scenekit geometry morphers? Neither blender nor cinema 4D do from my testing.
- Does the USDZ format support geometry morphers? I know the usdztools from the apple developer page supports blendshapes.
- What other file formats might support geometry morphers import into XCode?
- Do Scenekit's geometry morphers duplicate vertex data for each morph?
Basically the only research I can find on the matter is here, where it is still complicated: https://medium.com/better-programming/exporting-a-3d-character-from-blender-2-8-to-xcode-and-implement-like-animoji-using-arkit-scenekit-3d223aa6a29f
