Quick Landscape is a demo scene designed for creating miniature 3D terrains and dioramas. The foundation is a subdivided plane that users can shape by moving vertices to form hills and valleys. A Geometry Nodes setup automatically populates the surface with trees, offering controls for density, distribution, and custom prefab selection for standard or snowy trees. The terrain's colors are automatically generated based on elevation. Additionally, a Remesh modifier is included to convert the smooth landscape into blocky, voxel-style terrain.
