I would be careful about the license: DAZ3D has a separate (paid) license for their models used in real time 3D.
Oh, quite. But the OP didn't ask about licensing, just where they were obtained from.
Licensing is something you always need to check. There are many sites that offer various free models that can work with many different applications, but the models may have restrictions on what you can actually do with them. Just because they aren't paid for doesn't mean you have carte blanche with them. (And even if you
did pay for them, licensing terms still apply.)
For clarity, Daz is fine with you using the models sold through their store for just about anything as long as the output of the process is a 2D image. Commercial, non-commercial, done with Daz Studio, done with another program - pretty much OK across the board. Even if you're producing animations that
look 3D, if the actual stuff that you distribute is 2D, you're pretty much compliant with their license terms.
As
@Winterfire says, if you actually take one of their assets (even a modified version) and embed it into a program, then you need the Interactive license for the asset in question. (And it's an asset-by-asset deal, and many assets don't offer one.) So if the folks that did House Party
did use Daz assets, then presumably they took care of that. Daz also has restrictions on 3D printing of things based on models distributed thru their store.
License terms for Daz-compatible models sold on other stores (Renderosity, Renderotica, etc.) may be vastly different, however.
