Okay, so I lost my Oblivion disk for a month or so and found it again. After loading my last save, I noticed a big problem: I can't see the environments. I managed to "feel" my way around a little bit and find a few doors (this save was inside the Anvil Castle foyer). Inside of buildings, the world is black. Outside, the world is blueish purple. I can bring my inventory menu up and change stuff no problem but I can't see anything (except the HUD). I tried reloading other saves and had the same problem (the preview pic on the load menu showed the environments as they should be). I didn't have this problem the last time I played and I haven't loaded any new mods. Has anyone else had this problem? If so, how did you resolve it?
