Detailed explanation of matters needing attention in 3dmax lighting setting

3DMax lighting setting is a very important part of 3D modeling, which can add atmosphere to the scene and create different situations and effects. However, if you want to set lights in 3DMax, you need to pay attention to several points. Maybe many friends who are preparing to study or studying 3dmax don't know what the main points of 3dmax lighting settings are, so we will explain them in detail and learn together! Detailed explanation of key points of 3dmax lighting setting: 1. First of all, the light should be good, not too bright will make the process confusing and difficult to handle, and the display and rendering speed will be seriously affected. Only the necessary lights can be kept. In addition, we should pay attention to the application of light projection, shadow mapping and material mapping. Wherever you can use maps instead of lights, you'd better use maps. For example, when viewing from the outside at night, it is more convenient and effective to display the lighting effect in the window using self-luminous maps than using lighting simulation. Don't leave the light on, or the success rate will be very low. We should resolutely not keep unnecessary lamps. 2. Secondly, the lighting should reflect the light and shade distribution of the scene and have a sense of hierarchy. Don't put all the lights across the board. Use different types of lights as needed, such as spotlights or floodlights; According to the need to determine whether the light is projected and the strength of the shadow; Determine the brightness and contrast of the light as needed. If you want to get a more realistic effect, you must do some work on the light attenuation. You can temporarily turn off some lights to eliminate interference and set other lights better. 3. Knowing that the light in MAX can be surreal, learn to use the functions of "exclusion" and "inclusion" of light to determine whether the light illuminates or projects an object. For example, in order to simulate the lighting and projection effect of candlelight, we usually place a floodlight on the wick of the candle. If the desk lamp does not cast a shadow on the candle, the huge shadow it creates on the table may be a headache for a long time. In architectural renderings, the method of "exclusion" is often used to prevent light from illuminating or projecting some objects. 4. Lighting should follow the process from theme to part and from simple to complex. For the formation of lighting effect, we should first adjust the angle to set the main style, and then adjust the attenuation of light to enhance the sense of reality. Finally, adjust the color of the lights and make some details changes. To truly simulate the effect of natural light, we must have a deep understanding of natural light sources. It will be helpful to read more books on photography and lighting and do experiments. The lights used in different occasions are different. When making indoor renderings, in order to show a gorgeous effect, some main lights are often set to light orange, which can achieve the effect that materials are not easy to achieve. In addition to the above points, 3dsMax lighting settings also have the following points: 1. Selection: Choose the correct lighting type according to the needs of the scene, such as point light source, spotlight, directional light source, etc. 2. brightness level: According to the scene requirements and lighting types, adjust the lighting brightness appropriately to achieve the desired shadow effect and overall brightness. 3. Location of light sources: Different types of light sources will produce different light and shadow effects, so when setting lights, you need to choose appropriate light source types according to the needs of the scene, such as point light source, parallel light source and spotlight. In addition, the number, location, brightness, color and other parameters of light sources, as well as the interaction with the surface materials of objects and other factors need to be considered. Arrange the position of lights reasonably, and avoid placing them too far away from the center of the scene or too dense, otherwise it will cause unnatural light and shadow effects. 4. Lighting color: You can set the lighting color according to the needs of the scene. For example, yellow light can create a warm atmosphere, and blue light can create a calm atmosphere. 5. Halo effect: Halo effect refers to the strong light effect around when light passes through a transparent object or shines on the surface of the object. In the lighting setting of 3dmax, more realistic lighting effects can be created by adjusting the parameters of halo, such as the color, size and intensity of halo. In the scene that needs to render the halo effect, we can increase the ambient light and adjust the light intensity. In 3dmax, the setting of lighting is a very important part, which can not only enhance the realism and atmosphere of the scene, but also directly affect the final rendering effect. Therefore, you must pay attention when setting 3dmax lighting! Above, we have shared so many points for attention in 3dmax lighting settings in detail, I hope you can master them!
