Materials tab

When Unity imports a SpeedTree Model without any Material assigned, it uses the Unity diffuse Material. If the Model has Materials, Unity imports them as sub-Assets. You can use the Materials tab to change how Unity deals with Materials when importing your SpeedTree Model.

The Materials tab contains these sections:

(A) The Location and Materials settings allow you to control whether Unity imports or extracts the Materials inside the imported Asset.

(B) The Remapped Materials allow you to remap the imported Materials to existing Materials in your Project, or to extract the imported Materials and create separate Assets at a location of your choice.

(C) The preview pane displays the SpeedTree Model with its Material.

Location

The Location property
The Location property

The Location property defines how the SpeedTree Asset accesses its Materials. The rest of the properties on the SpeedTree Materials tab change depending on which of these options you choose.

Valor Descripción
Use Embedded Materials If you select this option, Unity keeps the imported Materials inside the Asset. You can optionally remap the imported Materials to existing Materials in your Project.
This is the default and recommended value.
Use External Materials (Legacy) Indicates that this Asset was imported with a previous version of Unity. If you select this option, Unity automatically extracts Materials and places them in a Materials folder at the same location as the Model.

Materials

Click the Extract Materials button to extract Materials that are embedded in your imported Asset. This is greyed out if there are no Materials to extract.

If you are importing a Material with a default Texture as a Normal Map, the following message appears:

Because the Texture Importer settings appear in another Inspector window, Unity offers to perform this fix for you:

  • Click the Fix now button if you want Unity to automatically change the Texture Type to Normal Map on all the affected Texture files.
  • Click the Ignore button to import the Texture file without changing its settings.

Remapped Materials

This section displays the list of Materials mapped to each LOD level for this SpeedTree Asset.

If you already have a set of Materials you want to use for this Asset, expand the On Demand Remap group and click the Search and Remap button.

After remapping any Materials, click the Regenerate Materials button to re-import the external Materials with the latest import settings.

Warning: Re-importing the external Materials removes any manual modifications you made to the Material files.
