The scene has 4 identical spot lights, which produce the following effect: As shown in the image, the combination of lights produces areas with different intensity. Could limit the intensity? I thought about light probes. But work at runtime, can you change position/color, or the light intensity for different groups?. I've also thought of using a vertex color shader to create ambient light on the object, and change color, clamp intensity through its vertex color. Is there a shader like this?
