Point lights are blinking on and off as the camera moves

Questions & Answers
1

I have two directional lights that are very low and a bunch of point lights throughout the scene that handles the majority of the lighting. The issue Im having is that certain lights will blink off and back on as I move through the scene. I have all the camera and lighting settings at the default, and I was wondering what could be causing this and how to fix it.

A few issues that might be part of the problem (though I’ve tested changing things with no luck) are that all the prefabs I have are very small. A meter in the world is about 1 unit the way I have it set up. I put lights inside objects (lanterns) though pulling them out doesn’t really fix anything. The main issues are caused with the larger meshes like the ground, which is all one mesh.

It also occurs mostly when rotating the camera, which I have tweened to rotate around the player character 45 degrees with every button press.

Any help would be greatly appreciated.

So I figured this out. I set all my point lights to important on the render mode settings of each light. Im not sure what exactly this does, but it definitely fixed the problem.

This is probably related to Pixel Light Counts, which are set in quality settings. For performance reasons, all meshes have a maximum number of lights that can affect them at once, and the engine will try to pick lights that it’s more likely the player can see (for example, lights closer to the camera). You need to reduce the number of lights that are active at a given time.
