Good points! I use Unwrap 3D Pro (Cost lest than $50) in between the Daz3D and the Game Engine or other apps because it seems to always import the rigged model and export it well.
daz3D is very underrated in Game Development. I see people using it for CG work and even stand in for film but rarely see people take advantage of the character creation kit.
It is good cover and concept art to.
I have contacted Third Party artist that make assets for Genesis and Victoria 4 when I wanted to use a texture or a model and I have never been turned away so far. They will either say mention in the credits or just say go for it:-)
I’m not making money yet so I have not had to ask Daz for permission yet or buy the $500 license. I only have the license for the Character Creation kit right now.
