rocky cave diorama 3d model

Create a modular set of natural trail‑style terrain pieces designed. The terrain should feature realistic outdoor elements such as layered rock shelves, fractured granite boulders, rounded river stones, embedded roots, and fallen logs. Include natural erosion patterns, cracks, undercuts, and weathered surfaces. Add logs that are partially buried, split, or angled, with bark texture and exposed wood grain. Incorporate small crevices, uneven ground, and subtle elevation changes. Design slopes and pitches between 15° and 45°, with occasional sharper breakovers and small ledges. Include natural gaps between rocks ranging from 10mm to 25mm to create realistic channels, cracks, and tire‑sized passages. The terrain should be multipart, printable, and assemble cleanly on the tile surface. Prioritize the look of a real forest trail, creek bed, or desert canyon, with organic shapes and believable geological structure.
