Lights getting brighter

I have created a simple animation with two buildings and a camera path. I lit each building with sunlights that only affect the building (by putting them on seperate layers). When I rendered out my animation, in some parts of the path where the camera rotates down, the objects all get brighter for an instant. Does anyone know how to fix this?

what is the spec and hard values on the building’s materials?

if spec is 0 you don’t see a bright dot, surfaces look more diffuse (less like glas, the specular dot is a simulation of the reflection of the light source)

also since concrete has some spec it would be a good idea to turn hardness all of the way down (a softer more bluury specular dot instead of a sharp point)

A quick test would be to render that frame as a still with No Specular button pressed for the lights.

Moving the point of view will change the specularity highlights.

Yep, it was the specularity. When I turned it off, everything looked fine. Thanks!
