I think it depends on the environment you choose from the Marketplace but I’m 99% sure it should be a simple enough thing. You might also want to read up on how to play sounds via blueprints as well as all the fun stuff available in audio cues. That way you could strip all existing sounds and add your own in exactly the way you’d want.
Probably a simple answer but I’d like to make sure before I start. I’m doing my dissertation in music on horror game audio. My level design skills are non-existent and I don’t want to spend the majority of my time designing an environment. If I purchase an environment from the store will I be able to swap out the audio for my own? This includes music, foley and ambient noises.
