For a flickering light effect, which component of a light should be adjusted?

Adjusting the intensity of a light is instrumental in creating a flickering light effect. The intensity determines the brightness of the light source. By varying the intensity over time, one can simulate the dynamics of a flickering flame or a malfunctioning bulb, which is characterized by rapid and irregular changes in brightness. This change can be made to occur in a rhythmic or erratic manner to achieve the desired visual effect.

The other components, such as color, spotAngle, and colorTemperature, serve different purposes. While changing the color may affect the hue of the light, it does not inherently create the flickering illusion. The spotAngle relates to the cone of light that a spot light emits, which influences how spread out the light appears, but not its flickering quality. ColorTemperature deals with the warmth or coolness of the light, affecting its overall appearance but not the flickering effect itself. Focusing on intensity adjustments is the most direct way to achieve the specific visual phenomenon of flickering in lighting design within Unity.
