When I run my scene however with a few dim omnilights, the surrounding mesh is way too bright, as if the lights are on full brightness.
The reason I have the omnilights is that I am creating a "video wall" in my game that shows streaming video. To recreate the effect of the video lighting up the surrounding area, I have four omnilights spaced evenly in front of the wall that are animated to match the content of the video.
I wonder if it is related to baked lighting or something? Any suggestions appreciated.
Here's an image showing the problem (video wall is off in editor, streaming a video in game). In the game image, the roof appears to have a white light source shining on it that I can only assume is one of the omnilights.
