3dmax用光域网使用经验（Experience of using optical domain network for 3DMAX） Experience of using optical domain network for 3DMAX Am 3DMAX experience with SkyLight (sky light) SkyLight is used to simulate daylight effects. The user can set the color of the sky or specify the map for itself On: used to turn on or off the sky lights. Select the check box and use the sky lights to illuminate the scene during the shadow and rendering calculations. Multiplier (multiplier): magnify or reduce the intensity of light by specifying a positive or negative value. Sky Color (sky color) option group Use Scene Environment (use scene environment): select this option, will use the Environment and Effect dialog box in the environment settings to set the color of the light. This setting is valid only if the ray tracing is in active state. Sky Color: to select this option, click the color swatch box to display the Color Selector dialog box and select the color of the sky lamp. Map: maps can be used to affect the color of sky lights. The check box is used to control the activation of map; trimmer on the right side of the map is used to set the use percentage (if the value is less than 100%, it will map color and sky color mixing); the None button is used to specify a map. The map is valid only if the ray tracing is in active state. Render (render) option group Note: this option group is valid only when the Default scan line renderer is currently used and the ray tracing is not activated. Cast Shadows (projection shadow): when selected, sky lights project shadows. Default to turn off. Note: this option is not valid when using radiosity or ray tracing. Sky lights do not cast shadows when rendering with Activeshade rendering levels. Rays per Sample (the number of rays per sample): set the amount of light used to calculate the sky lights on the given point in the scene, with a default value of 20. When making animation, you need to increase this value (about 30) to eliminate flickering phenomenon. R
