Well, from my own perspective, I don't need a 3d secondary representation of every interactable in the game. When I observe a corpse, it's obviously a corpse, adding some "backlighting" doesn't suddenly change it into a sheet of paper. That is, in essence, what your screenshot shows. It's a highlight, not a separate model. It's only purpose is to inform us that we can interact with that item, no matter what it is. The fact that it requires us to either press a hotkey, or mouse over it, should be enough to demonstrate how much of a problem this isn't, from my perspective, so I guess, I'm surprised anyone has a real issue with it?
