Hyper-Realistic 3D Simulation Prompt: Melting Hourglass

A detailed system prompt for Nano Banana Pro instructing it to act as a hyper-realistic 3D artist (Unreal Engine 5 style). The prompt defines a structure for generating an image of a transparent object filled with content, simulating physics like refraction. This specific command generates an image of an antique hourglass glass sculpture, melted and distorted, filled with sand flowing like liquid metal, small rusted gears, and time flowing backward, set against a desert sunset with warm orange and purple gradients.
