Cardboard Cutout.

[DaMuncha]

In the tower there is two windows you can open, slightly ajar. The lower window as you are walking up the staircase works fine. But if you zoom into the 2nd (higher window)using the(Maginfier), the sky above the trees is cutout. And the sky in the window. The window frame and the trees them selves are fine, but where the sky should be it is black.

Im assuming that space in the window was supposed to be the moving clouds shader you see outside, but inside the tower looking out through that window it looks like a cardboard cutout with a black background.

I've only seen this bug once and it was ages ago, before we did the Director's Cut. I honestly thought it was fixed but for some reason it came back when we rebuilt the game. Unfortunately this is a problem with an asset and can't be fixed that easily. It should look just fine in the second day, though.

I second this, same issue as the original poster.
