This high-precision 3D asset reproduces the aoyu ridge ornament of Hui-style ancient architecture, fully restoring the classic shape and century-old weathered texture of roof ridge decorations in Hui-style buildings. The model accurately depicts the three-dimensional form of the ornament. It elaborately recreates the carved details of fish-dragon scales, dorsal fins and head ornaments, and faithfully presents the textural layers and wear traces of brick carvings or lime sculptures. It also features mottled weathering, water erosion marks and natural aged patina on the surface, delivering an authentic antique texture of Hui-style architectural components. As an iconic decoration on roof ridges of Hui-style architecture, the aoyu ornament boasts both practical and symbolic values. It secures the ridge and prevents rain leakage. The image of fish transforming into dragon embodies folk wishes for fire prevention and building protection, and represents the cultural implication of "carp leaping over the dragon gate". It is an exquisite masterpiece integrating intangible heritage brick carving and lime sculpture techniques, ancient architectural craftsmanship and traditional oriental auspicious culture.
