Bake doesn’t go well

Regarding the lighting in the exhibition room, we are baking a light map so that the room will be illuminated with global illumination.

Since we can’t place many spotlights to illuminate the exhibits in real-time settings, we place them as bake settings, but they don’t reflect well on the light map.

Even after trying various settings based on information on the internet, we still can’t bake it properly.

Apart from this, we also tried lighting with ‘Emission’ type materials, but this was also quite difficult. In order to influence global illumination, not only the intensity of light but also the area of the material is important. The key is to multiply strength and area. It’s obvious, but it’s difficult.
