Greetings
DAZ to Unreal workflow.
From my personal experience I can say that the best workflow and cinematic quality is to export from Daz to Blender Genesis 2,3,8 character in FBX format and then add “mdd” animation made in DAZ. Only in this way you it can avoid body sprains and a thousand other problems and headaches.
Subsequently export alembic to unreal.In Unreal you have to create all materials including those for the eyes, there is no need to replace them.Just create the right material and they become really beautiful.The alembic format is indispensable for complex and extreme poses and animations . Of course I tried exporting FBX animations from blender with use of diffeomorphic but the results are not so good. There are too many warping and other problems. I think, but I would not be mistaken that currently there is no plugin or better way that can equal workflow described above.
I am attaching some pictures of my work.
Of course I have to do right lighting. This I use only for demonstration purpose.
Best regards
