How does Patreon relate to copyright? Particularly interested in DAZ.
When you buy Models, Props, Materials, etc, from the Daz3d store you're given a license along with that purchase.
This license covers a wide ranged of uses.
Such as using their content "models, props, etc" in your own games which you can then make money from.
When purchasing a Model, prop, etc be sure to check which license comes with it as some artists ask that you pay for a different "more expensive license" for you to use their content in your games to make money.
Most stores online which you use to buy Daz3d assets will also come with a license.
Such as Renderotica.com
