canyon terrain 3d model

Highly detailed Mediterranean canyon landscape with a winding river flowing through the center. Terrain features steep limestone cliffs with visible stratified rock layers, erosion patterns, cracks, and natural weathering typical for Mediterranean geology. The canyon walls are rugged and irregular with realistic rock formations, small ledges, and broken stone surfaces. The river is narrow and natural, carving through the canyon with smooth stones and a slightly uneven riverbed. Surrounding terrain expands beyond the canyon with rolling rocky hills and natural terrain transitions. Vegetation is sparse Mediterranean type: small pine trees, low shrubs, dry grass patches, and scattered bushes growing between rocks and along the riverbank. Model requirements: ultra detailed terrain geometry high polygon density realistic rock surface variation natural erosion and terrain noise clean topology suitable for rendering large environment scale optimized but high-resolution mesh single cohere
