Why does the effect of lights change when the camera moves?

When there are fewer than 40 lights in the operating viewport, real-time lighting effects are displayed according to a precise ray tracing algorithm.

When there are more than 40 lights in the viewport, the lighting optimization algorithm will be utilized in the real-time preview to enhance the efficiency of real-time rendering. The effect of lights is approximated to improve the efficiency of lighting in the real-time preview.

When the camera moves, the number of lights in the viewport changes, causing a switch in the algorithm for the light preview, which may result in a change in the lighting effect.

The lights are calculated according to the accurate algorithm when outputting images, ensuring the details of images.
