Some interiors like Illuminated Order's Inverness Tower and Skygem's Lab from Cult of the Clouds look like this:

If I disable shaders then you cannot see anything but the flames from lights, just a plain whitish-ness. The view returns to normal as soon as I leave those cells. Fortunately I do not have to spend much time in there (so far), but I am afraid there could be more cells like this. Any ideas?

It's an issue with all MGE versions I believe. It happens when an interior cell uses a certain setting for its fog I think. A fog density of 0 or something like that. Some setting that is at 0 for the cell anyway. If you change that to 0.1 it should fix the problem.

Which results in you not being able to see anything. Though in this case, your SSAO shader allows you to see a little.

Thank you, good to know. Interesting, I thought fog density zero mostly has been an issue for pitch-black areas only. I guess I will see some more of them in DNGDR in a few levels ahead.
