Many devs use models (whether they purchased them or stole them) from asset stores. Those devs don't have any copyright on those models, so other devs can use those same models as well. That is why you see certain models appear so often in many different games.why tho, inceton is the only one that gives a fuck about his renders being used, ive seen resources from being a dik in a lot of games, no one says a thing (mentioned that one because of your signature or w/e that is), same with a ton of games. Is so funny to see threads that develop this way. I can only think of one dev worse than inceton in value/money and i used to confuse them in the begining, the milfy city guy. Probably if he adds stuff at a decent pace people doesnt need to imagine and get inspired to move the story somewhere, but yeah better to DMCA.
The only issue would be whether the devs actually have permission to use the models from whoever the artist was that actually created the model. Either because they bought it or the model creator made them freely available for commercial/non-commercial use.
