SpeedTree Import Settings

When you put SpeedTree files in the Assets folder of your Unity project, the Unity Editor automatically imports and stores them as Unity assets.

SpeedTree import settings are specific to files for models created in SpeedTree. For information on models and animation created in other 3D modeling applications, refer to the Model Import Settings window.

Importing SpeedTree files to Unity

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, 9, or 10, you can 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 then 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
See in Glossary.

Wind settings

When you import an .st9 file to the Unity Editor, you can select the correct Wind algorithm to use for the new Unity asset.

Materials

By default, Unity imports SpeedTree model materials 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.

Customize how Unity imports the file
