I can't pin-point them, as I suspect NLT have done some custom shape dialling as well, but, I'm pretty certain the characters are all Genesis 2. I don't think the rendering was done in Daz, I actually suspect he used Octane in either 3DS MAX or Cinema 4D. Maybe Blender, but my biggest suspect is 3DS MAX due to the lighting and because of how complex, yet fluid the animations are.
Octane is the reason why skins look softer than in Daz. For Octane, one needs to (more or less) re-build the materials. A designer can use most of the textures made for the character, but how the textures are applied to the character and used to render a skin and such is different.
