Materials tab
You can use this tab to change how Unity deals with Materials and Textures when importing your model.
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.
| PropertyA generic term for the editable fields, buttons, checkboxes, or menus that comprise a component. An editable property is also referred to as a field. More info See in Glossary |
Function | |
|---|---|---|
| Import Materials | Enable the rest of the settings for importing Materials. When this option is disabled, no other settings appear in the InspectorA Unity window that displays information about the currently selected GameObject, Asset or Project Settings, alowing you to inspect and edit the values. More info See in Glossary. |
|
| sRGB Albedo Colors | Enable this option to use Albedo colors in gamma space. This is enabled by default. Disable this for Projects using linear color space. |
|
| Location | Define how to access the Materials and Textures. Different properties are available depending on which of these options you choose. | |
| Use Embedded Materials | Keep the imported Materials inside the imported Asset. This is the default option from Unity 2017.2 onwards. | |
| Use External Materials (Legacy) | Extract imported Materials as external Assets. This is a Legacy way of handling Materials, and is intended for Projects created with 2017.1 or previous versions of Unity. | |
Use Embedded Materials
When you choose Use Embedded Materials for the Location option, the following import options appear:
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
New imports or changes to the original Asset do not affect extracted Materials. If you want to re-import the Materials from the source Asset, you need to remove the references to the extracted Materials in the Remapped Materials list. To remove an item from the list, select it and press the Backspace key on your keyboard.
Naming
Define a naming strategy for the Materials.
| Property | Function |
|---|---|
| By Base Texture Name | Use the name of the diffuse Texture of the imported Material to name the Material. When you don’t assign a diffuse Texture to the Material, Unity uses the name of the imported Material. |
| From Model’s Material | Use the name of the imported Material to name the Material. |
| Model Name + Model’s Material | Use the name of the Model fileA file containing a 3D data, which may include definitions for meshes, bones, animation, materials and textures. More info See in Glossary in combination with the name of the imported Material to name the Material. |
Search
Define where Unity tries to locate existing Materials when it uses the name defined by the Naming option.
| Property | Function |
|---|---|
| Local Materials Folder | Find existing Materials in the local Materials subfolder, which is in the same folder as the Model file). |
| Recursive-Up | Find existing Materials in all Materials subfolders in all parent folders up to the Assets folder. |
| Project-Wide | Find existing Materials in all Unity Project folders. |
Use External Materials (Legacy)
When you choose Use External Materials (Legacy) for the Location option, the following import options appear:
This option extracts Materials and saves them externally instead of saving them inside your Model Asset. The Naming and Search properties help Unity find imported Materials to map to the Model.
Before Unity version 2017.2, this was the default way of handling Materials.
