ancient circular altar 3d model

A top-down cinematic shot of a single-layered, circular ancient altar partially embedded in a stone floor. The altar is made of heavy, weathered dark stone with a thick 24k polished gold rim. The surface is intricately engraved with deep, hollowed-out grooves and sockets following a complex orbital pattern with multiple concentric circles and rectangular indentations. Small patches of green grass and moss are growing sparsely around the outer edge of the altar and from the cracks in the floor. No center stone, just empty carved-out tracks. The setting is a grand, decaying ancient temple with golden dragon statues and flickering torches. High-contrast lighting, volumetric sunbeams reflecting off the gold, photorealistic, 8k resolution, Unreal Engine 5 render style, intricate metallic textures, masterwork.
