unity Lighting总结

Posted 2020-10-08

上一篇博客已经详细的介绍GI了，接下来我们讲点实际的，怎么烘焙场景及注意事项。

 

一、Light

Property:	Function:
Type	当前灯光的类型。有四种类型:Directional, Point, Spot and Area。
Range	灯光照射的距离 (只有Point和Spot光源有这个属性).
Spot Angle	聚光灯照射范围所张开的角度(Spot light only).
Color	光的颜色
Mode	指定光的模式. 三种模式 Realtime, Mixed and Baked。
Intensity	光照强度
Indirect Multiplier	改变间接光的强度，间接光光线从一个对象反弹到另一个对象。如果值大于1则反射光将变得更亮，小于1反射光暗淡
Shadow Type	阴影类型:Hard Shadows, Soft Shadows, or no shadows 。
Baked Shadow Angle	烘焙时，软化边缘阴影,让他们看起来更自然。（Directional ）
Baked Shadow Radius	烘焙时，软化边缘阴影,让他们看起来更自然。（Point or Spot）
Realtime Shadows	实时阴影。
Strength	Use the slider to control how dark the shadows cast by this Light are, represented by a value between 0 and 1. This is set to 1 by default.
Resolution	Control the rendered resolution of shadow maps. A higher resolution increases the fidelity of shadows, but requires more GPU time and memory usage.
Bias	Use the slider to control the distance at which shadows are pushed away from the light, defined as a value between 0 and 2. This is useful for avoiding false self-shadowing artifacts. See Shadow mapping and the bias property for more information. This is set to 0.05 by default.
Normal Bias	Use the slider to control distance at which the shadow casting surfaces are shrunk along the surface normal, defined as a value between 0 and 3. This is useful for avoiding false self-shadowing artifacts. See documentation on Shadow mapping and the bias property for more information. This is set to 0.4 by default.
Near Plane	Use the slider to control the value for the near clip plane when rendering shadows, defined as a value between 0.1 and 10. This value is clamped to 0.1 units or 1% of the light’s Range property, whichever is lower. This is set to 0.2 by default.
Cookie	Specify a Texture mask through which shadows are cast (for example, to create silhouettes, or patterned illumination for the Light).
Draw Halo	Tick this box to draw a spherical Halo of light with a diameter equal to the Range value. You can also use the Halo component to achieve this. Note that the Halo component is drawn in addition to the halo from the Light component, and that the Halo component’s Size parameter determines its radius, not its diameter.
Flare	If you want to set a Flare to be rendered at the Light’s position, place an Asset in this field to be used as its source.
Render Mode	Use this drop-down to set the rendering priority of the selected Light. This can affect lighting fidelity and performance (see Performance Considerations, below).
Auto	The rendering method is determined at run time, depending on the brightness of nearby lights and the current Quality Settings.
Important	The light is always rendered at per-pixel quality. Use Important mode only for the most noticeable visual effects (for example, the headlights of a player’s car).
Not Important	The light is always rendered in a faster, vertex/object light mode.
Culling Mask	Use this to selectively exclude groups of objects from being affected by the Light. For more information, see Layers.
