Paint a low-poly mesh landscape right in the Scene view: shape hills, paint colours and textures, draw paths, dig lakes, grow GPU grass and scatter trees and rocks.Requires the Universal Render Pipeline (URP).Paint Land turns a mesh into a world you paint by hand. Open Tools > Environment > Paint Land, pick a tab and drag across the land in the Scene view. Everything saves by itself, every stroke can be undone with Ctrl+Z, and your work stays put when you rebuild the land from a new model.It's made for stylised, low-poly worlds with soft vertex colours, like Astroneer. It works on a mesh, not Unity Terrain, so you keep your own shape and triangle style.Seven brushes in one windowShape: raise, lower, smooth, flatten, roughen or restore the land, and make ramps. Colliders, colours, grass and plants follow the ground as it moves.Ground: paint the ground's colours with a soft brush, or colour whole triangles for a crisp low-poly look. Pick From Land grabs a colour straight off the ground.Textures: paint up to 8 textures (rock, sand, mud and more), soft-edged or on whole triangles.Paths: draw paths at any width with crisp edges. You can choose to clear trees and plants out of the way.Water: paint lakes. The water level is wherever you start the stroke. The bed is dug out for you, with a smooth shore and foam at the edge, and anything in the water is removed. Or add a sea over the whole land in one click.Grass: add a GPU grass field over the whole land and paint where it grows thicker, thinner or not at all.Scatter: scatter trees, rocks, flowers or any prefab in natural clumps and patches. Each clump gets random colours, sizes and lean, with optional colliders that fit each kind.Quick controlsShift or the Erase tick rubs outCtrl+click picks up a colour, texture or height[ and ] change the brush sizeEsc stops painting, Ctrl+Z undoes a strokeFast at runtimeGrass is built in 16 m chunks near the camera and drawn on the GPU, thousands at a time. It thins out with distance and casts no shadows.Scattered plants share tinted materials (one per colour) so they still batch.Grass stays off paths, steep slopes and water automatically.What's includedThe Paint Land editor window and all its brushesLand, Water and Grass Field shaders (URP)A sample land and a demo sceneDocumentationRender pipeline: URP only. Water needs URP's Depth Texture, which Paint Land turns on for you.Unity 6Editor tool. The painting is editor-only; the grass field and water run in builds.Works on a mesh, not Unity TerrainBrush sizes: shape up to 400 m, ground up to 300 m, textures up to 120 m, grass and scatter up to 80 m, paths up to 40 m wideUp to 8 painted texture layersData is saved to plain asset files (a shape file and PNG masks for textures, paths and grass), so it works with version controlScattered objects are normal scene objects under a "Land Scatter" parentFull undo (Ctrl+Z) per strokeC# source includedShaders: Land (vertex colours), Water, Grass FieldDependencies: none beyond URPThe C# code and shaders were written with the help of an AI coding assistant (Claude), then directed, tested and refined by the developer. No AI-generated art, models or textures are included.
