This is a Riddler puzzle in the studios hub where the player has to direct a Riddler robot to unlock the trophy.
Just outside the trophy area the windows are smashed, allowing wet moss and damp seep into the area. Evidence of birds, spiders and some dead rodents add a bit of life to the scene.
Sitting there making a bird droppings decal was an interesting career moment... :)
I was responsible for scene composition and layout, early lighting and modeling and texturing. The nature of the film set meant there is quite a bit of shared assets from the other level artists.
