Common Redshift Light Parameters

常见红移光参数

Every Redshift light shares the features below with the exception of some paramters depending on the light type in which case they are called out.

每个红移光都具有以下特征，除了一些参数，这取决于光的类型，在这种情况下，它们会被调出。

 

 

Ray Contribution

Affects Diffuse

影响扩散

Enable or disable diffuse contribution on shaders. By default physical lights affect the diffuse component of shaders.

启用或禁用着色器的漫反射效果。默认情况下物理光线会影响着色器的漫反射效果。

Affects Specular

影响镜面效果

Enable or disable specular contribution on shaders. By default physical lights affect the specular component of shaders.

启用或禁用着色器的镜面效果。默认情况下，物理光线会影响着色器的镜面效果。

Matte Shadow Illuminator

亚光阴影照明器

Specifies whether the light can illuminate 'Matte Shadow' surfaces (see Common Redshift Light Parameters shader).

指定光线是否可以照亮“哑光阴影”表面(请参阅公共红移光参数着色器)。

Affected by Refraction

受折射影响

This option allows you to control how specular reflections are affected by rough/refractive objects that block the light and whether or not the light rays bend as they pass through. Prior to 2.6.10 this option was not available and the light rays would never bend. Specular ray bending is an important effect for rendering realistic-looking glass and lenses.

这个选项允许你控制镜面反射是如何被阻挡光线的粗糙/折射物体影响的，以及光线是否在通过时弯曲。在2.6.10之前，这个选项是不可行的，光线永远不会弯曲。镜面光线弯曲是真实感显示玻璃和镜头的重要效果。

• Never 从来没有 - Specular rays do not bend. This is the legacy lighting behavior. - 镜面光线不弯曲。这是遗留的照明行为
• Auto 自动 - Specular rays bend through refractions if they are not too rough and bias towards not bending if they are rough. - 镜面光线如果不太粗糙，会通过折射而弯曲; 如果粗糙，则倾向于不弯曲
• Always 一直都是 - Specular rays bend through refractions regardless of ray roughness. 镜面光线通过折射弯曲而不管光线粗糙度

GI Max Trace Depth

最大追踪深度

This option lets you override the maximum trace depth for GI rays on a per-light basis.

此选项允许您在每光的基础上覆盖 GI 射线的最大跟踪深度。

Scale

比例

The light scale parameters covered below allow you to tweak a lights contribution to different shading elements individually. These parameters give you full creative control to adjust exactly how much a light impacts a shaders various elements, they can even bet set above 1.

下面的光照参数允许你对不同的阴影元素进行单独的调整。这些参数可以让你完全创造性地控制光线对着色器各种元素的影响程度，他们甚至可以设置在1以上。

The example scene used below contains 3 capsules with different shaders that collectively showcase diffuse, reflection, refraction/single-scattering, and multiple sub-surface scattering shading elements. At the top of the room is a Redshift Physical Area light with a ray contribution of 1 for all values unless otherwise specified and a small amount of volume scattering. For reference, here is an example of what those elements look like on their own so you can better understand what the scale example images are affecting.

下面使用的示例场景包含3个具有不同着色器的胶囊，它们共同展示了漫反射、反射、折射/单次散射和多个次表面散射阴影元素。在房间的顶部是一个红移物理区域光，除非另有说明，所有值的光线贡献为1，并有少量的体积散射。作为参考，这里有一个这些元素本身看起来是什么样子的例子，这样你就可以更好地理解比例例子图像的影响。

 

Diffuse Scale

漫反射比例尺

Scales the intensity of the light's diffuse contribution.

缩放光的漫射贡献的强度。

 

Glossy Scale

光滑的鳞片

Scales the intensity of the light when seen through reflections/specular or refractions.

缩放通过反射/镜面或折射看到的光的强度。

Sometimes very bright lights can appear noisy when seen through 'rough' reflections/refractions, even with hundreds of samples. Bringing down the intensity can help reduce noise.

有时非常明亮的光线通过“粗糙”的反射/折射会显得嘈杂，即使有数百个样本。降低强度有助于减少噪音。

Single Scattering Scale

单次散射比例尺

Scales the intensity of the light when seen through sub-surface single scattered materials. A value of 0.0 disables single scattered lighting.

缩放光的强度时，通过亚表面看到的单一散射材料。值为0.0时禁用单点散射照明。

 

Multiple Scattering Scale

多次散射尺度

Scales the intensity of the light when seen through sub-surface multiple scattered materials. A value of 0.0 disables multiple scattered lighting.

缩放光的强度时，通过亚表面多个散射材料看到。0.0的值禁用多个散射照明。

 

GI Scattering Scale

消化道散射标度

Scales the intensity of the light's global illumination contribution. A value of 0.0 disables global illumination lighting.

调整光线的全局光源强度，如果值为0.0，全局光源照明将被禁用。

 

Shadow 阴影

Enable

启用

Enable or disable shadow casting.

启用或禁用阴影施放。

Transparency

透明度

Specifies the transparency of the shadows cast by the light. Smaller values yield darker shadows. The default value of 0 will produce a completely black shadow. A value of 1 will produce no shadow at all.

指定光投射阴影的透明度。较小的值产生较暗的阴影。默认值0将生成一个完全黑色的阴影。值为1将不会产生任何阴影。

The example below shows how a completely opaque sphere's shadow transparency can be controlled by this light setting.

下面的例子展示了一个完全不透明的球体的阴影透明度可以通过这个光线设置来控制。

Softness

温柔

Specifies edge softness for non-area light shadows. A value of 0 means no softness and will yield sharp shadows. Values above 0 will produce softer shadow edges.

为非区域光影指定边缘柔和度。值为0意味着没有柔软度，会产生尖锐的阴影。数值大于0会产生更柔和的阴影边缘。

Samples

样本

Specifies the number of ray samples for non-area light soft shadows. The higher the value of the Softness parameter, the more samples will be necessary to achieve noise-free results.

指定非区域光线软阴影的光线采样数量。柔度参数的值越高，需要的样本就越多，才能得到无噪声的结果。

Softness Affects Gobo

软化影响 Gobo

Enables soft gobo texture projection, to match the softness of the shadows, giving the same appearance as if the light was an area light.

使得柔软的 gobo 纹理投影，与阴影的柔和相匹配，给人一种如同光线是区域光线的感觉。

Volume 音量

Contribution Scale

捐款比额表

Scales the intensity of the light's global volume scatter contribution. The default value of 0 disables volume scattering for the light.

缩放光的全局体积散射贡献的强度。默认值0禁用光线的体积散射。

Samples

样本

Specifies the number of samples to use for the volume scattering effect. Increasing the number of samples will reduce noise, but at the cost of performance.

指定用于体散射效果的样本数。增加采样数量会降低噪声，但是会损害性能。
