“环境”面板位于页面右侧，显示场景环境的可编辑参数列表。可用的面板参数会根据所选环境而变化。

单击“环境”面板图标 () 打开面板：

环境参数概述如下：

• 圆顶

  • 无限大小 - 将环境设置为一个无限大的圆顶。在这个环境中，地平线非常远，以至于相机在场景中的位置没有影响，只有相机的观察方向有影响。这适用于外部场景。当不使用无限环境时，必须提供相机到地平线的距离（地平线距离）。这更适合于室内场景或包含的外部场景，在这些场景中，不仅仅是相机的方向，相机的位置也会影响环境的视野。

    • 地平线距离 - 从环境中心到地平线的距离。

  • 半球 - 将环境设置为半球。半球环境的地面位于从照明环境投影的半球底部。当您希望场景固定在地面上而不是漂浮在环境中时，这是很有用的。启用后，将三脚架高度设置为您的规格。

    • 三脚架高度 - 拍摄环境图像时相机距离地面的高度。这用于将环境圆顶的下半部分投影到平坦的地平面上。

  • 照明强度 - 环境图像中包含的照明强度的乘数。小于 1 的值会降低环境光照的亮度，而大于 1 的值会增加环境光的亮度。

  • 旋转 - 环境圆顶绕竖直轴旋转。

• 图像

  • 库环境 () - 如果未被自定义图像覆盖，则用于照亮场景的库环境。标准是默认环境。

  • 自定义图像 - 使用用户提供的 HDRI 环境图像替代环境圆顶。图像应采用 360/180 度的纬度/经度，最好采用 .hdr 或 .exr 格式。有关更多信息，请参见为场景添加自定义“环境”。

    • 图像 - 自定义 HDRI 照明环境图像。

• Lighting (Render Studio Advanced only)

• Allows placement of area light sources of various shapes directly in the environment, along with the ability to move and resize them.

  

  Once the light is placed, select it's middle point. Once selected, it's shape can be changed. Click and drag to move the light to any location in the environment. You can add as many lights as required.

  

  An example of 3 light shapes: Disc (left), Rectangle (middle), Ring (right)

  • Properties

    

    • Shape - Physical shape of the light: Disc, Rectangle, or Ring. Click the environment to place a light.

    • Direction - Position of the light in the environment. The horizon and right side of the scene are at 0 degrees. Enter an X and Y value in degrees.

    • Radius (Disc or Ring shape only) - Radius of the disc or center line of the ring light.

    • Width (Rectangle shape only) - Width of the rectangular light.

    • Height (Rectangle shape only) - Height of the rectangular light.

    • Thickness (Ring shape only) - Width of the ring light centered on its radius.

    • Tint - Color of the emitted light. Click the pencil icon to edit the color used from the color picker. Colors can be selected visually by clicking on the color area, by entering a hex or RGB value, or by selecting a swatch at the bottom of the picker.

    • Intensity - Unitless intensity of the emitted light.

    • Softness - Determines whether the light has soft or hard edges. Higher values soften the edges of the light. Lower values harden the edges of the light.

  • Base environment

    

    • Use scene environment - Uses the scene's environment, typically selected from the Environments library, on which the light is added.

    • Gradient - Adds a graduated light. The light is added to the background environment.

      

      • Sky tint - Color of the light emitted from the sky. Click the pencil icon to edit the color used from the color picker. Colors can be selected visually by clicking on the color area, by entering a hex or RGB value, or by selecting a swatch at the bottom of the picker.

      • Sky intensity - Unitless intensity of the light emitted from the sky.

      • Horizon tint - Color of the light emitted from the horizon. Click the pencil icon to edit the color used from the color picker. Colors can be selected visually by clicking on the color area, by entering a hex or RGB value, or by selecting a swatch at the bottom of the picker.

      • Horizon intensity - Unitless intensity of the light emitted from the horizon.

      • Horizon softness - Determines whether the horizon has soft or hard edges. Higher values soften the edges of the horizon. Lower values harden the edges of the horizon. A value of 0 removes the horizon.

      • Horizon height - Position of the horizon in the environment. 0.5 positions the horizon in the center. Higher values move the horizon higher in the sky. Lower values moves the horizon lower to the ground.

      • Ground tint - Color of the light emitted from the ground. Click the pencil icon to edit the color used from the color picker. Colors can be selected visually by clicking on the color area, by entering a hex or RGB value, or by selecting a swatch at the bottom of the picker.

      • Ground intensity - Unitless intensity of the light emitted from the ground.

    • Solid color and intensity - Adds a solid tint and adjustable intensity for the light. The light is added to the background environment.

      

      • Tint - Color of the light emitted from the environment. Click the pencil icon to edit the color used from the color picker. Colors can be selected visually by clicking on the color area, by entering a hex or RGB value, or by selecting a swatch at the bottom of the picker.

      • Intensity - Unitless intensity of the light emitted from the environment

• 地面 - 带有位置和反射率控制的虚拟地平面。

  • 自动高度 - 根据最低物体自动设置地面高度。

  • 反射 - 允许地平面反射场景。

    • 反射率 - 地平面的反射率数值。

    • 粗糙度 - 地平面的粗糙度。较低的数值会产生类似镜像的反射。较高的数值会模糊反射。

  • 阴影强度 - 地面阴影强度。值为 1 会得到物理上正确的结果。小于 1 的值会产生更亮的阴影，而大于 1 的值会产生更暗的阴影。

• 日光 - 编辑以下日光参数（适用于某些环境，例如 Preetham）。

  

  • 国家/地区 - 从国家/地区列表中选择

  • 省份 - 从所选国家/地区的省份列表中选择

  • 城市 - 从世界主要城市列表中选择。

  • 日期 - 通过直接单击月、日和年按数字选择年份和日期，或者单击日历图标从选择列表中选择日期。

  • 时间 - 通过单击小时、分钟和上午/下午按数字选择时间，或者单击时钟图标从时间选择列表中进行选择。

  • 时区 - 从 UTC 时区列表中进行选择。

  • DST - 选中后，会针对夏令时进行调整。

“日光”参数仅适用于某些环境（例如 Perez 和 Preetham）。请参阅编辑带有位置和时间的环境

若要调整面板宽度，请将光标悬停在面板边缘上。当光标变成双面箭头时，单击并拖动以调整面板大小。
