I'm trying to export to a CC model to Unity for use on an iPhone X face tracking ARKit app. 

Key things I need would be the blend shape morphs for the face puppeteering. Also LOD and poly reduction, as it's for use in Unity - as a mobile game.

How do I make sure the right blendshapes are in and/or preserve the blend shapes from a Daz exported model into CC for this use? 

My initial and ideal flow is to have the model be from Daz, but have been told that the LOD poly reduction does not work with morphs?
