heya,
So yep, the majority of the art is done with DAZ3D except for a few of the flyover animations that are in the game--those were done with Blender (of which I don't have any experience with. One of the other devs named Lazy Jayke did those for me). So I kinda learned Daz on the go. I sorta just started writing stuff and then tried to google how to do what I actually wanted to do. So you can imagine I did a lot of googling. Basically, you can find a lot of tutorials on youtube for Daz. I would say focusing on positioning and lighting are the majority of the time consuming stuff that requires more skill and competency with the program than anything else.
Glad you're enjoying the game so far though :)
