How to create 3D indoor lighting
When you use radiosity to simulate realistic lighting scenes, be sure to pay attention to the following points: Scene size: Make sure your scene has the correct size, and consistent units (a light in a 120 meter There is a big difference between a tall room and a 120cm tall room). Lighting: You must use Photometriclights. And make sure the brightness of these lights is in the correct range. Natural light: To simulate natural light, make sure you use IESsun and IESSky. They can give correct lighting information based on a specific location, date, and time. Material reflectance: You must ensure that the reflection value of the scene material is consistent with reality. For example: a wall painted with white paint , its reflectivity is about 80%; however, a pure white material (RGB: 255, 255, 255) has a reflectivity of 100%. At this time, you must manually adjust the reflectivity. Exposure control: Exposure control is equivalent to the aperture of the camera. You can use it to control the final rendering result and optimize the rendered image. Physically based radiosity workflow using photo-photometric lighting: Inspect and adjust the dimensions of objects in the scene to match their physical size, and adjust the reflectivity of materials to match their physical properties. Place photometriclights into your scene. You can place your virtual lights the same way you place lights in the real world. For related information, you can check the light brightness table that comes with HELP. Select the Rendering menu Environment dialog box
