Hello there,

I appear to have encountered a lighting bug in my environment. I have multiple different hallways that all contain copies of the same light. Some work as intended, but others have some strange tendencies. Below is an image of how the light looks in most of the areas.

Above is how the light should look. However, when approaching the origin of the light, the appearance of the light changes drastically. By just inching closer, the lighting resembles the image below. It is an instant switch that occurs as my character runs past the light in game, and also in the development area.

Any idea how to fix this?

Hi bnisbet -

I am not seeing the same results that you are seeing above. Are you seeing the same results in 4.7 or 4.8? If you could put together a small test project for me to use that would be helpful.

Thank You

Eric Ketchum
