I've got a strange problem where as you move around and look at things at different angles, where my lights illuminate certain areas they sort of flicker like they're turning on and off. Anybody know why this might be?

I had a problem like that in one particular patch of ceiling. I had placed a lantern underneath it and it was interfering with a ceiling light. Removing the lantern fixed it. How close and how many lights do you have in that area?

Maybe 8 lights around the ring of the imperial fort tower kit with one in the middle. They cross a tiny bit when I hit the L key, but I didn't think enough to be a problem.

I encounter this issue all the time. I assume the lights are non-shadow lights? Try moving them around, rotating them or replacing them.

You can only have a few lights work on a single object in the game at a time. Having 8 lights on one object (large room for example) will cause them to blink. Remove the lights, put up dummy lights, and add one 'big' actual light object and your problems will go away.

You can also press 'L' to see the light radius, so see how many lights are impacting your cell.

There is also a way to visually view light troubles in a cell, but I cant remember how to do that...
