ancient colosseum 3d model

Create a highly detailed, realistic 3D model of the ancient Roman Colosseum as depicted in the movie Gladiator. Make it historically inspired while matching the dramatic appearance of the film: enormous elliptical amphitheater, multiple tiers of weathered stone arches, tall outer walls, Roman columns, worn marble, cracked stone, dirt, dust, and subtle damage from age and battle. Include the detailed arena interior with a large sandy fighting floor, surrounding spectator seating, underground hypogeum structures partially visible beneath the arena, ramps, gates, stairways, and realistic architectural supports. Use accurate Roman proportions and believable construction. The model should be fully 3D, game-ready, modular, and optimized while maintaining high visual detail. Add realistic PBR materials for stone, marble, wood, and sand. No people, weapons, text, logos, or modern objects. Include exterior and interior geometry.
