To ensure bloom effects affect lower-level emission maps in a sci-fi corridor, what property should be decreased?

The threshold setting is crucial when working with bloom effects in Unity. This property determines the minimum brightness level that a pixel must reach before it contributes to the bloom effect. By decreasing the threshold, you allow a greater range of bright areas in your scene to trigger the bloom effect, including those from lower-level emission maps. This means that even the more subtle emissions can create that glowing, atmospheric look characteristic of sci-fi environments.

Conversely, if the threshold is set too high, only the brightest spots would emit bloom, potentially overlooking lower emissions that contribute to the overall aesthetic you might be aiming for in a sci-fi corridor. Adjusting the threshold effectively controls which areas of the image are affected by the bloom post-processing effect, helping to create a more immersive and visually appealing scene.
