LMAO..
no... not at all... at the contrary.
DAZ is specifically created for create renders to share and use , including commercial. DAZ have absolutly no problem with that. in fact, they even encourage peoples to use DAz for creating renders to share. that's the whole concept of the software.
the commercial use of renders have no problem on DAZ. as you own assets, its ok.
the only part DAz can be a bit hard to get is if you plan to make a 3D game and use the whole 3D assets in your game (like a char model). for that, you need a specific overpriced license for each assets used.
but sharing renders, for free or commercialy, is perfectly legal for DAZ as long you own legaly the assets used on the renders.
