设置散射光的颜色。
ScreenSpaceFogEffect
设置散射光束的聚焦指数。
控制光束的锐利程度。值越大，光束越集中、越锐利。
ScreenSpaceFogEffect
设置散射光束开始计算的距离。
ScreenSpaceFogEffect
设置雾气的颜色
ScreenSpaceFogEffect
设置雾气的基础密度。
ScreenSpaceFogEffect
设置雾气层的基准高度。
ScreenSpaceFogEffect
设置雾气的高度衰减系数。
控制雾气密度随 Y 轴升高而衰减的速度。值越大，雾层越薄，边界越清晰。通常在 0.05 到 1.0 之间。0.05 适合厚厚的、缓慢过渡的大气，0.5 适合贴地面的薄雾。
ScreenSpaceFogEffect
设置雾气的最大不透明度。
ScreenSpaceFogEffect
设置雾效开始计算的距离。
ScreenSpaceFogEffect
Experimental
The input color space.
Protected Experimental
设置定向光的反向方向向量，必须归一化 (normalize)。
ScreenSpaceFogEffect
设置主相机
ScreenSpaceFogEffect
设置主场景
ScreenSpaceFogEffect
设置噪声在世界空间中的频率。
控制雾气团块的大小。值越小，团块越大越平缓；值越大，团块越小越密集。大型云海推荐 0.005 到 0.05。地面团状雾推荐 0.05 到 0.15。
ScreenSpaceFogEffect
设置雾气扰动在世界空间 X 轴和 Z 轴上的流动速度。
ScreenSpaceFogEffect
设置噪声对雾气基准高度的最大扰动幅度。
控制雾气基准面上下波动的最大高度（米）。通常设置为一个世界高度值，如 5.0 (轻微波动) 到 50.0 (明显起伏)。这个值决定了雾气团块的垂直对比度。
