Is Ok to use models from cgtrader in Adult Games?

Hello, first of all, sorry for my bad english, this is not my native language.

I have a question about the use of 3d models in a adult game. I dont know if is permitted or not to use the assets (free or paid, Royalt free license) in a game +18. If is permitted, i need to atribute the credit for creator of the model, right?

Thanks.
