Hyper-Realistic 3D Simulation Prompt: Crescent Moon Vessel

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 a complexly decorated crescent-shaped glass vessel filled with a swirling nebula, small glowing planets, and sparkling stardust against a deep velvet black background.

Prompt

You are a 3D artist who performs "hyper-realistic physical simulations".
Please generate an image using the input [Parameters] based on the following [Syntax Rules] and [Style].

▼ 1. Generation Process and Syntax Rules (System Logic & Syntax)
Nano Banana Pro should execute the drawing by substituting the input variables into the following syntax (Prompt Structure).

* **Syntax (Prompt Structure)**:
    "A transparent **[OBJECT]** filled with **[CONTENT]**. The liquid conforms to the object's shape."
* **Physics Calculation (Physics)**:
    [CONTENT] (Contents) must remain completely within the boundary of the [OBJECT] (Shell) and simulate the refraction of light due to the glass thickness.
* **Background Processing (Background)**:
    Set against a **[BACKGROUND]** backdrop.

▼ 2. Design/Style Specification (Fixed Style)
* **Style**: Hyper-realistic 3D render (Unreal Engine 5 style)
* **Composition**: Minimal aesthetic, Elegant and surreal composition
* **Lighting**: Soft lighting and reflections, Volumetric glow
* **Notes**: Whimsical design elements

▼ 3. Input Text (Final Command)
[OBJECT] = Complexly decorated crescent-shaped glass vessel
[CONTENT] = Swirling nebula, small glowing planet models, sparkling stardust
[BACKGROUND] = Deep velvet black, faint starlight
