I’m gonna be real with you look at the environment and how many unique assets are in it, not to mention the lighting, and then take a brief look at this game’s update schedule so far and the dev’s history.
there’s no shame in using content packs and assets made by others on the web, it’s necessary to allow for game development at this school to this level of gameplay quality, but if you aren’t careful you’ll end up spamming high poly high detail textured objects all over a scene and then the game doesn’t run well. I guess it could be something else but I think that’s really the most important thing here.
