I want to make it clear, ModularCity is build for PC/Consoles games and is AAA assets . If after its release you paid it and you are not satisfied with its content you can send a refund mail to marketplace team with your desagrement, but I doubt that anyone will do it, cause, it is a real AAA games assets.
By default all textures Resolution have been set to 1K ( due to amount of substances files, I will face Memory bandwith issues )
