===== How Does It Work? =====
Using SpeedTree with UE4 is a three step process:

  * **Create or purchase a SpeedTree model**.  Whether you use models from our [[http://www.ue4trees.com|library]] or create one from scratch using the SpeedTree Modeler, you'll need a model to get started.  Models consist of the SpeedTree files (.spm, .srt) and the textures and component meshes (.obj, .fbx) associated with it.  Click [[gettingstarted|here]] to learn more about creating models in SpeedTree.

  * **Import the model into UE4**.  SpeedTree models are imported into UE4 like any other asset.  They come in as a static mesh with extra vertex attributes to implement wind and smooth LOD.  You can do anything with them that you can do with a static mesh inside of UE4. Click [[importing_models_into_ue4|here]] to learn more about import SpeedTree models into UE4.

  * **Place models in your scene**.  Once imported, SpeedTree models can be placed or painted like any other static mesh.  Click [[working_with_models_in_ue4|here]] to learn more about placing SpeedTree models in UE4.
