Is there a limit to how many stationary lights affect an object even with no overlap?
I'm adding a bunch of stationary lights to my scene but it seems past a certain amount, additional lights won't render after building my lighting.
As you can see I have no overlap between the lights and the debug stationary overlap disply mode confirms that.
I have 12 similar lights in my level, no overlap. I tried moving them around, they are fine as long as I don't build, but disappear as soon as I do. Could this be a limitation with stationary spot lights?

I've tried to see if I could get the same results, but could not.
In this test I place 25 spotlights, not overlapping, and built lighting:
Looking at your two images, If you move the light closer to the surface or extend it's radius or cone shape are you able to see any light there? Also, make sure it has a high enough intensity, if it's not set like the three that are working.
Is this after lighting has been built?

There shouldn't be any per-object limit for stationary lights, just the limit on overlapping at any position in space. It might be a bug that you are seeing.
One thing to try if you will - find BaseLightmass.ini and change the value MinUnoccludedFraction=.005 to MinUnoccludedFraction=0
Rebuild lighting and see if that causes all the lights to show up. If it does, we can fix it easily.
