This tool generates clean side wall geometry for Unity Terrains, helping you create solid terrain edges and cliffs quickly and efficiently.The demo scene is optimized for the Built-in render pipeline.Sometimes during environment or level design, Unity Terrains need proper geometry along their outer edges instead of open sides or visible gaps. Terrain Edge Wall is a lightweight tool that generates procedural side wall meshes directly from the terrain heightmap.The generated walls follow the terrain surface while extending down to an adjustable base position. Individual edges can be enabled or disabled, and edges shared with neighboring terrains can be excluded automatically. Adjustable sampling makes it possible to balance mesh detail and vertex count.Terrain Edge Wall does not modify the original terrain data. It supports automatic and manual updates, optional collision geometry, bottom-plane generation, multi-object editing, and mesh baking for production-ready scenes.The perimeter-based UV mapping keeps texture proportions consistent on rectangular terrains, making the tool suitable for cliffs, map borders, floating islands, cutaway environments, and stylized terrain chunks.FeaturesProcedural terrain side wall mesh generationAdjustable wall heightAdjustable heightmap sampling densityCustom material supportNon-square terrain supportMulti terrain supportAutomatic mesh updatesOptional bottom plane with a separate materialOptional Mesh Collider generationMesh bakingMesh vertex and triangle statisticsNon-destructive workflowMulti-object editingUndo / Redo supportLightweight| Documentation | Other Assets | Official Site |LimitationsUnity Terrain uses distance-based LOD.
