4K photorealistic 3D model of a weathered stone and wood ruin structure. Asymmetrical archway atop cracked stone steps, built from rough-cut grey-brown stone blocks with deep cracks, erosion, and moss growth. Dark, splintered wood beams form the stair rail and upper frame, showing dry grain and decay. Surface textures are high-resolution and realistic. Lighting is neutral, with soft ambient shadows. Ideal for realistic fantasy or medieval environments. Clean topology and game-engine ready., #arch#,
