It's complicated.
If you had money there was Daz To Hue workflow. You need to work with houdini(can be pirated).
If you don't want spend money you need Daz -> Blender (Diffeomorphic) -> unreal.
Also for now Unreal Engine 5.5 is bug fested hell hole. I never see such a release for long time. Epic try to do lots things.
Also full 3d game requires lots of background work. If you had good NVIDIA card stick with Daz, create income then try 3d.
Only real 3d game was
Seaside Mistery and it previous version The Twist Both are Unity and custom 3d models. Other 3d games are try to be game but unsuccessfull.
Daz TO Unreal plugins (both David's original one and Daz one) are not full solution last 3 years people try to make it (including me) and it was unsuccessfull. Daz To Hue starting to work really. At least Character and animation transfer with gens work properly.
Hoever there where cloths, hairs and jiggle bones problem. All on roadmap. I can barelly manage hair and cloths however they are not good enough.
Unreal Engine 5 is a beast, Godzilla grade beast. If you can tame it it was awesome.
However Daz3d can job done after 3 moths of hardwork. Just need good RTX card xx90 grade.
