terrain tile 3d model

Create a stylized low-poly modular fantasy terrain cube tile for an isometric action-adventure game inspired by Tunic. The model must be designed specifically for TileWorldCreator 3D autotiling and 9-slice terrain assembly. Perfect cube shape, flat grass top, vertical stone cliff sides, seamless on all four edges. Grass should use only 2-3 bright green tones with minimal detail and no baked shadows. Stone walls should consist of evenly spaced block-like rocks using only 2-3 gray/brown tones. Clean topology, UV-friendly, optimized low-poly, game-ready. Symmetrical design with consistent edge thickness so duplicated tiles connect naturally. Avoid asymmetrical details near borders. Suitable for center, edge, outer corner, and inner corner tiles. No floating objects, no background, isolated single model, isometric view, neutral lighting, soft hand-painted fantasy style.
