 +====== Basic Workflow ======
  
 +The SpeedTree Modeler, which runs separately from Unity, offers procedural and hand modeling tools that allow both efficiency and precision.\\
 +
 +>**Note**: SpeedTree 8 for Unity is compatible only with Unity 2018.3 and later.
 +>**Note**: Files exported by the SpeedTree for Unity Modeler will only work inside of Unity (.ST)
 +
 +===== Purchasing the Modeler =====
 +
 +SpeedTree 8 for Unity is available with a subscription that can be purchased here: https://store.speedtree.com/Unity/ The subscription will allow you to edit and create trees. Custom licensing is also available.
 +
 +Included in the subscription application are these features:
 +
 +  * [[kcmaterialspbr|Physically Based Rendering Material Workflow]]
 +  * [[seasons|Seasonal variations]]
 +  * [[kcmesh_anchors|Mesh Anchors]]
 +  * [[shape_control|Shape Control]]
 +  * [[fin_generator|Decoration Generators]]
 +  * [[fanunity| Unity specific wind]]
 +  * [[lod|LOD setup]]
 +
 +===== Free Export Only Mode =====
 +
 +Log in with a free SpeedTree Store account to export the new SpeedTree samples models to Unity.  [[exportonlymode|Export-only mode]] replaces our drop-in ready models on the SpeedTree store with a more flexible approach to bringing SpeedTrees to Unity. 
 +
 +Coming soon: v8 Drop-in-ready models will be available soon on the Unity Asset Store.
 +
 +SpeedTree models (.SPM) purchased from the store can be opened, allowing artists to change the seasons and wind options before exporting a SpeedTree runtime file (.ST).  Editing and saving are disabled in export only mode.
 +For the full version of SpeedTree for Unity, simply activate a subscription through the SpeedTree store.
 +
 +
 + 
 +===== How Does It Work?=====
 +
 +
 +SpeedTree 8 for Unity can open SpeedTree files (.SPM) and export them in a format specific to Unity (.ST). SpeedTree 8 for Unity will not export meshes outside of the ".ST" format and is incompatible with other game engines. 
 +
 +Using the SpeedTree Modeler is a three-step process:
 +
 +  - **Create or purchase a SpeedTree model:** Whether you use models from our library or create them from scratch using the SpeedTree Modeler, you’ll need a model to get started. Models consist of the SpeedTree files (.SPM) and the textures and component meshes (.OBJ, .FBX) associated with it. 
 +  - **Export the model as a ".ST" file:** SpeedTree models are [[expgame|exported]] directly into your Unity project. SpeedTrees can be exported with up to 3 LODs and a compatible wind for use inside Unity. 
 +  - **Import models into Unity:** SpeedTree models are imported into Unity 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 Unity.
