Hyper-Realistic 3D Simulation Prompt: Acorn Capsule Forest

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 a transparent capsule shaped like a giant acorn, filled with a miniature mossy forest, misty humidity, and small glowing mushrooms, set against a blurred forest green background with soft sunlight filtering through the trees.
