Program is called Koikatsu. It’s not quite a 3d engine, but with enough mods the community has managed to make quite a bit.
It’s on Steam as “Koikatsu Party” but you’ll need a good bunch of mods to get some use out of it.
alright, thought about using it for some personal projects
cheers!
most devs also use Chara studio to animate scenes with it (i belive chara comes with the steam download in the game folder)
