Material Preview

材质预览

To toggle the material preview on or off, click the arrow next to the preview (only in the Attribute Manager). To rotate the preview, right-drag (Windows) or Command-drag (macOS) or Shift-drag the preview.

要开启或关闭材质预览，请单击预览旁边的箭头(仅在属性管理器中)。要旋转预览，可以右键拖动(Windows)或命令拖动(macOS)或移动拖动预览。

To change the display settings for the preview, right-click (Windows) or Command-click (Mac OS) on the preview and choose the new settings from the context menu that appears.

若要更改预览的显示设置，请在预览上右键单击(Windows)或命令单击(Mac OS) ，并从出现的上下文菜单中选择新设置。

Ctrl+clicking in the preview window will turn the cursor into a color picker for the current channel color. This only works in the Material Editor (not in the Attribute Manager and also not for the Reflectance channel).

在预览窗口中单击 Ctrl + 将光标转换为当前通道颜色的颜色选择器。这只在材质编辑器中有效(不在属性管理器中，也不在反射通道中)。

The following commands are available in the Material Preview’s context menu:

下面的命令可以在材质预览的上下文菜单中找到:

Animate

动画

Enable this option to switch on animation for the preview. If enabled, the animation will be played automatically, without moving the Timeslider, according to the settings in the Preferences menu (see Frame Rate (FPS)).

启用此选项以打开预览动画。如果启用，动画将自动播放，不移动时间利得器，根据设置菜单中的设置(见帧速率(FPS))。

Open Window

打开窗户

This command opens a window containing a material preview that you can scale as desired. The window also has a context menu that lets you choose which scene is used to create the preview (e.g., sphere, torus) and whether the preview is animated. With the Auto option, you can ensure changes made to the material are updated automatically. If the option is disabled, you must manually click on Update. Materials and shaders can also be placed here via Drag & drop.

此命令将打开一个包含材质预览的窗口，您可以根据需要进行缩放。该窗口还有一个上下文菜单，可以让你选择哪个场景用于创建预览(例如，球体，环面) ，以及预览是否动画。使用“自动”选项，您可以确保对材质所做的更改会自动更新。如果禁用此选项，则必须手动单击“更新”。材质和着色器也可以通过拖放放置在这里。

Default, Small, Medium, Large, Huge

默认值，小，中，大，大

Here you can choose the size of the material preview. The Default setting corresponds to the Default Size specified in the preferences on the Material tab.

在这里你可以选择材质预览的大小。Default 设置对应于 Material 选项卡上的首选项中指定的 Default Size。

Various Scenes

各种场景

Here you will find a series of self-explanatory scene names that can be used for the Material Preview. Default uses the scene defined in the Preferences menu (Material tab).

在这里，您将找到一系列自我解释的场景名称，可用于材质预览。默认情况下使用首选项菜单(材质选项卡)中定义的场景。

Reset Rotation

重置旋转

You can rotate the preview shape, as mentioned earlier, by right-dragging (Windows) or Command-dragging (macOS) or Shift-dragging the preview. The Reset Rotation button restores the preview shape to its original angle.

您可以旋转预览形状，如前所述，通过右拖动(Windows)或命令拖动(macOS)或移位拖动预览。重置旋转按钮恢复预览形状的原始角度。

Project Settings

项目设置

Most of these parameters change the size of the object that is used by the preview. So how is this useful?

这些参数中的大多数都会更改预览所使用的对象的大小。那么，这有什么用呢？

Suppose you have created a material that uses a displacement map with Height on the Displacement tab set to 100 m or higher. Suppose also that the object used by the preview is a cube that has sides that are 100 m long. This cube would be too small to adequately display the Displacement map.

假设您已经创建了一个材质，它使用一个置换贴图，置换标签上的高度设置为100米或更高。还假设预览使用的对象是一个边长为100米的立方体。这个立方体太小，无法充分显示位移图。

In such cases, simply change the object’s size using the Preview Size or Relative Scale parameters. The Original Size box displays the object’s original size. If the material is animated, specify the start frame for the animation using Animation Start.

在这种情况下，只需使用预览大小或相对缩放参数更改对象的大小。“原始大小”框显示对象的原始大小。如果材质是动画的，使用 Animation Start 指定动画的起始帧。

Animation Start

动画开始

Here you can define at which point the material preview animation should begin.

这里您可以定义材质预览动画应该从哪一点开始。

Environment Color, Environment Strength

环境色彩，环境强度

These two parameters allow you to define environment lighting (i.e. ambient light) for the preview. You can choose the color and brightness of the environment light.

这两个参数允许您为预览定义环境照明(即环境光)。你可以选择环境光的颜色和亮度。

Material preview for Node Materials

节点材质的材质预览

The material preview for Node Materials has fewer commands. The following is new:

节点材质的材质预览有更少的命令。以下是新的:

HUD Preview

平显预览

If the material is open in the Node Editor and the Node is selected, the HUD can be enabled or disabled in the Node Editor’s own Attribute Manager.

如果材质在节点编辑器中打开并且节点被选中，HUD 可以在节点编辑器自己的属性管理器中启用或禁用。
