Either it is unique to my install or nobody has complained about this .nif in the Missing Pauldron in Shivering Isles. It is supposed to be a set of three windows with light rays. The windows show correctly but the light rays are angled blocks of light. The Unofficial Shivering Isles Patch missed it. Does anyone else see what I see?

I couldn't find an updated mesh for it anywhere and may be forced to disable it through console. The only texture it points to is the stained window glass texture.

Found the culprit. Weather All Natural has an option to use only the real lights.esp and change the name of the .bsa to reflect the file. I didn't see it as a suspect because it didn't have ManiSmityLitRay.nif in the .bsa. But turning off the All Natural - Real Lights.esp stopped the upper windows in the Missing Pauldron from being solid rectangles of light. The light shafts are gone completely, though.

Edit:
But since I know the culprit and it is not anything in my game, I can just enable it again and disable the light blocks in the Missing Pauldron. The windows won't be lit, but they will still be there without the blocks.
