Unreal Engine Produces Digitally Preserved Humans

The head is a photogrammetry scan, the hair/groom was done in Houdini and the eyes are done with Substance Designer.

This is Unreal Engine 4.26 with raytraced shadows, ao, reflections, translucency, etc.

When people talk about having themselves preserved digitally after they die, this is pretty much what they're talking about.
