SpeedTree Import Settings window

When you put SpeedTree files in your Unity project’s Assets folder, Unity automatically imports and stores them as Unity assets. To view the import settings in the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary, select the file in the ProjectIn Unity, you use a project to design and develop a game. A project stores all of the files that are related to a game, such as the asset and Scene files. More info
See in Glossary window. To customize how Unity imports the selected file, use the properties on the Model and Materials tabs on this window. SpeedTree 9 assets imported as .st9 files also have a Wind tab.

Note: These settings are for importing models created in SpeedTree. For information on models and animation created in other 3D modeling applications, see the Model Import Settings window.

Unity recognizes and imports SpeedTree model assets in the same way it handles other assets. If you’re using SpeedTree Modeler 7, re-save your .spm files using the Unity version of the Modeler. If you’re using SpeedTree Modeler 8 or 9, save your .st or .st9 files directly into the Unity project folder. The SpeedTree Importer generates a prefabAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary with the LOD GroupA component to manage level of detail (LOD) for GameObjects. More info
See in Glossary component configured. You can instantiate the prefab in a sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary as a common prefab instance or select the prefab as a tree prototype and paint it across the terrainThe landscape in your scene. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape. More info

Materials come embedded in the imported SpeedTree model as sub-assets. If you want to make adjustments to the materials, you can extract them to a location of your choice or re-use existing materials with Material Remapping.
