I am trying to use the ARKit/VirtualFaceContent to project high quality scn models onto a face. When I load the object in the XCode model viewer, the object displays correctly. However, when the model is then loaded onto the mobile app, all the textures (metalness, roughness, normal, and transparent) do not display, only the diffuse color does. I.e. we are able to set diffuse contents, but none of the other textures.Overall, we are trying to create a node that is transparent in some areas and opaque in others. Setting the diffuse and transparent contents allows for this to happen (verified by looking at the node in the Xcode scn viewer) but the object looks opaque on the mobile app because only the diffuse contents get displayed.https://stackoverflow.com/questions/59384825/displaying-textures-on-arkit-virtualfacecontent [see attached links on StackOverflow post]
