# Trees

> Create and customize Trees

> **Important:**
>
> The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
>
> It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
>
> For more information on migration, refer to [Migrating from the Built-In Render Pipeline to the Universal Render Pipeline](/engine/6000.7/manual/render-pipelines/universal-render-pipeline/introduction/installing-and-configuring-urp/upgrading-from-birp.md.md) and [Render pipeline feature comparison](/engine/6000.7/manual/render-pipelines/choose-a-render-pipeline/feature-comparison.md.md).

Trees add realism, interest, and a sense of place to a terrain.

There are two ways to create new tree models:

* Use the [Tree Editor](/engine/6000.7/manual/creating-environments/script-terrain/terrain-trees/class-tree.md) to create tree models in the Unity Editor. The Tree Editor works only with the Built-In Render Pipeline. For most uses, the SpeedTree Modeler replaces the Tree Editor. For backward compatibility with content created before SpeedTree was introduced, use Tree Editor.
* Use the [SpeedTree Modeler](https://store.speedtree.com) to create trees with advanced visual effects, such as smooth level of detail (LOD) transition, fast billboarding, and natural wind animation. SpeedTree supports the Built-In Render Pipeline, the Universal Render Pipeline (URP), and the High Definition Render Pipeline (HDRP). For more information, refer to the [SpeedTree Modeler documentation](http://docs9.speedTree.com/).
