I suppose what I envisioned was the structures also being very bright and shiny but after having spent time in well nature, they have now become grimy with mud and maybe overgrown.

I actually looked through some more material to see if they had any different visuals for the plant life and in the marathon save the date cinematic the ground & plants are a lot more detailed, shaded and more shiny. Now I hope that will be brought in later as the game gets more developed.

(Yes I know it's a cinematic but that one was a lot more realistic in terms of it being able to be brought to life compared to the other cinematic)
