Unable to See Lights in Editor

[palistov]

Yknow I've actually started experiencing issues with my lights too, particularly shadowcasting spotlights with a gobo map. I spent about 15 mins testing and there's something (I don't know what though) that causes a shadowcasting spotlight with a gobo map to disappear when not pointed a certain direction. The problem is only occurring for me when in a map with lots of objects already present. And it's definitely not just an editor issue, the exact same issue occurs in-game as well.


Update on the matter:
I think I figured out what causes the problem: SSAO and/or occlusion culling. I turned off SSAO and the problem went away. When I turned it back on, it re-appeared. I had culling primitives in the map, and once I fixed them, the problem went away in-game. For some reason the problem didn't appear in the editor, even before I fixed the planes. I also updated my graphics driver, so that may have been a factor as well....anyways I suggest updating your graphics driver, that might solve it for you.

Anyways, here's a list of things I did which may help you fix this:
Fix culling planes
Update graphics card driver
Change boxlight blend to add
Delete map_cache files
