Materials 选项卡

可以使用此选项卡更改 Unity 在导入模型时处理材质和纹理的方式。

When Unity imports a Model without any Material assigned, it uses the Unity diffuse Material. If the Model has Materials, Unity imports them as sub-Assets. You can extract Embedded Textures into your Project using the Extract Textures button.

Use Embedded Materials

从 Location 选项中选择 Use Embedded Materials 时，将显示以下导入选项：

Click the Extract Materials and Extract Textures buttons to extract all Materials and Textures that are embedded in your imported Asset. These are greyed out if there are no sub-Assets to extract. Below these buttons, Unity displays any messages about the import process.

The On Demand Remap section provides the Naming and Search properties which allow you to customize how Unity maps imported Materials to the Model. Click the Search and Remap button to remap your imported Materials to existing Material Assets. Nothing changes if Unity can’t find any Materials with the correct name.

Unity displays all imported Materials found in the Asset in the Remapped Materials list. If Unity can’t automatically match each Material to an existing Material Asset in your Project, you can set references to the Materials yourself in this list.

Remapped Materials

新导入操作或对原始资源的更改不会影响提取的材质。如果要从源资源重新导入材质，必须删除 Remapped Materials 列表中对提取的材质的引用。要从该列表中删除某一项，请选择该项，然后按键盘上的 Backspace 键。

Naming

定义材质的命名策略。

Search

定义 Unity 尝试在使用 Naming 选项定义的名称时查找现有材质的位置。

Use External Materials (Legacy)

从 Location 选项中选择 Use External Materials (Legacy) 时，将显示以下导入选项：

此选项提取材质并将它们保存到外部，而不是保存在模型资源内部。Naming 和 Search 属性可帮助 Unity 找到导入的材质以映射到模型。

在 Unity 2017.2 版之前，这是默认的材质处理方式。
