There is no fixed pattern for this. The scene is different and the lighting is different. But there are basic principles for lighting settings. When making outdoor architectural landscape, the main light source should choose the target parallel light and make it project at an angle of about 40-0 degrees with the building. The light projected from this angle can make the architectural modeling more three-dimensional and layered. When setting the parameters of the main light source, in general, the value of its light multiplier can be set to about 1- 1.5. It should be noted that the main light source should use ray tracing shadow to represent the shadow produced by real light. The setting of auxiliary light sources can be increased according to the light perception of the scene, usually only one or two lights are needed, which is mainly used to improve the light perception effect of shadow surfaces and dark parts in buildings. As for the background light, it depends. As for glass, it is best to paste a picture of a building or landscape in the reflection diagram, and the value of 50- paint 0 is almost the same, so as to reflect the surrounding environment. When making outdoor night scenes, the main light source can be the target spotlight or floodlight. When using the target spotlight, the lighting point of the lamp is usually set at the bottom of the building, so that the light shines from bottom to top. Whether using target spotlight or floodlight, it is best to use long-distance attenuation to make its environment more realistic. In addition, you should pay attention to one when setting lighting parameters. The multiplication of each lamp light should be changed, so as to have a more layered feeling. Second, the spacing arrangement of the main light sources should be reasonable, and it is difficult to achieve the ideal effect if it is too sparse or too dense. 3. Sometimes it is necessary to set two or three floodlights far away from the building to simulate the ambient light at night. Generally, the multiplication of light is below 0.2. 4. Choose the appropriate background image to set off the light effect atmosphere of the scene. As for the glass, there are two ways to set it. One is to choose a bright material (self-luminescence is 1 00), and the other is to paste a picture of the hotel interior on the reflection map, which will be more realistic.
