+# Terrain Workflow Tests
|
|
|
+
|
|
|
+Testing in this area revolves around the construction of Terrain surfaces, applying materials and vegetation to the terrain, and ensuring proper physics reactions with terrain. Workflows in this area will lead into each other, ultimately resulting in a saved level with physicalized terrain defined by heightmap with macro and detail materials applied.

|
|
|
+## Project Requirements
|
|
|
+AutomatedTesting project, or another project with Terrain/PhysX Gems enabled.

|
|
|
+Test guidance will sometimes note specific issues to watch for. The common issues below should be watched for through all testing, even if unrelated to the current workflow being tested.
