I recently found an interesting article that mentions possible issues you will encounter when using DS models in Unreal:
https://crazyrestosim.wordpress.com/…/daz3d-to-ue4/
In short, the things to watch for, are animation artifacts caused by the fact that DS uses Dual Quaternion skinning, but game engines use Classic linear skinning and also DS has corrective morphs to make animations look better, but game engines will not use those morphs “automagically” and you will need to somehow manually apply them (not sure, how, and not sure if you need to create your own corrective morphs from scratch or can reuse the DS ones). Also, bone rotation axis can cause problems for programmatic animations and mentioned corrective morhs.
Also, DS exported models lack roughness / normal maps and LODs.
The author mentions some ways to solve the issues but unfortunately does not provide detailed tutorials. I haven’t yet found a complete DS -> Unreal pipeline tutorial anywhere, although I have searched Unreal forums, youtube, paid courses and have asked experienced DS / Unreal content creators to create such a tutorial, maybe collecting donations on Patreon etc. to pay for their efforts - I’m sure people will be interested because I have found some quick&dirty DS -> Unreal video that was funded through Patreon, but the video was just another quick start and not complete guide. So, yeah, we still have no “the Ultimate fool-proof DS -> UE guide” and have to collect everything from bits and pieces.
