Channel Shaders

频道着色器

Channel shaders have their name because they can only be used for a single material channel (i.e., a material property such as Color, Transparency, etc.). You can, however, copy shaders including all of their properties and paste them into other material channels.

通道着色器之所以有它们的名字，是因为它们只能用于单一的材质通道(例如，材质属性，如颜色、透明度等)。然而，你可以复制着色器，包括他们的所有属性，并粘贴到其他材质渠道。

Shaders are loaded in the Material Editor in place of bitmap textures or films. To open a channel shader, click the triangle button next to the Texture box and choose the shader from the drop-down list that appears. To edit a shader, click the shader’s name or preview picture.

着色器被加载到材质编辑器中来代替位图纹理或者电影。要打开通道着色器，单击纹理框旁边的三角形按钮，并从出现的下拉列表中选择着色器。要编辑着色器，请单击着色器的名称或预览图片。

The following parameters will appear.

将显示以下参数。

Basic Properties

基本属性

You can assign a name to the shader. This name is used to refer to the texture in the XPresso editor and Timeline.

您可以为着色器指定一个名称。此名称用于指代 XPresso 编辑器和时间轴中的纹理。

The Blur Offset and Blur Scale are present on the Basic Properties tab of all shaders.

模糊偏移和模糊尺度出现在所有着色器的基本属性标签上。

Shader Properties

These are the individual properties for each shader. You will find descriptions for these properties in the following pages.

这些是每个着色器的单独属性。

Working with shaders in the Material Editor

在材质编辑器中使用着色器

Shader channels support multiple selections. 着色通道支持多重选择

Shader channels support multiple selections. 着色通道支持多重选择

For example, you can select multiple materials and assign the same shader or texture to all of them in one go. Any changes that you make to the shader or texture will be applied to all the selected materials.

例如，你可以选择多种材质，然后一次性为所有材质分配相同的着色器或纹理。对着色器或纹理所做的任何更改都将应用于所有选定的材质。

If the selected materials have different settings for an option, the option is highlighted in light blue and in addition is marked with a .

如果选定的材质对某个选项有不同的设置，则该选项将以浅蓝色突出显示，此外还用。

Click the x to set all selected materials to the same state.

单击 x 将所有选定的材质设置为相同的状态。

You can drag & drop shaders from one material channel to another. Drag the shader’s preview onto the name of a different material channel, wait for the target channel’s parameters to appear, then drop the shader onto the Texture text box. 您可以拖放着色器从一个材质通道到另一个。将着色器的预览拖到不同材质通道的名称上，等待目标通道的参数出现，然后将着色器拖到纹理文本框上
Pop-up material channels in the Material Editor: Drag a shader preview over the channel of another shader and hold briefly. The menu for the channel over which the preview is held will open and you can drop the preview onto the channel. 在材质编辑器中弹出材质通道: 在另一个着色器的通道上拖动一个着色器预览并暂时保持。预览所在频道的菜单将打开，您可以将预览放到频道上

2D Shaders

2 d 着色器

2D shaders are always flat (like image textures) and can be applied to an object using a projection method (see Projektion).

二维着色器总是平面的(像图像纹理) ，可以应用到一个对象使用投影方法(见 Projektion)。

Tip: 提示:
All 2D channel shaders can be positioned precisely by adjusting the texture axis system. By changing the texture axis’ length, the positioning can be modified (in addition to the modifications created by the shader settings). 所有的二维通道着色器可以通过调整纹理轴系统精确定位。通过改变纹理轴的长度，可以修改定位(除了由着色器设置创建的修改)

The tiling and texture length can also be fine-tuned.

瓷砖和纹理长度也可以微调。

3D Channel Shaders

3D 通道着色器

3D channel shaders are also called Volume shaders because they permeate an object’s volume and in essence come to light through its surface.

3D 通道着色器也被称为体积着色器，因为它们渗透到物体的体积中，本质上是透过物体表面发光。

Ambient Occlusion Shader

环境遮挡着色器

Display Color

显示颜色

Bitmap Shader

位图着色器
