Well, TableTop Simulator flakes out between 35k & 50k for an OBJ. But, you can also import it into Unity, then export it as an asset package and TTS stops caring about polycount and loads it differently (hence how we can get
some really high-rez shapes in the game). It's, basically, the best way to import DAZ character assets in, assuming you want a decent level of detail (so, actual character models, but mooks are fine being low-poly OBJs).
It'll also do animation and other cool effects, but my level of Unity understanding is too low to do that stuff yet.
