**[PROMPT START]**
**1. Role & Goal Assignment:**
You are an expert VFX concept artist and astrophysicist collaborating on a key sequence for a hard science-fiction project. Your goal is to generate a photorealistic, scientifically plausible, and visually spectacular concept for the catastrophic meltdown of an icy comet’s core. The focus is on the complex interplay of fluid dynamics, particle emissions, and light.
**2. Scene & Environment:**
* **Location:** Deep space, located within `[e.g., the chaotic accretion disk of a protostar, a serene, empty void of interstellar space, the turbulent upper atmosphere of a gas giant, a dense, ethereal nebula]`.
* **Background:** The backdrop consists of `[e.g., a field of distant, cold blue stars, the swirling, incandescent gases of the Orion Nebula, the stark silhouette of a nearby planet, a blindingly bright magnetar in the distance]`.
* **Ambient Lighting:** The primary light source is `[e.g., a nearby blue giant star casting harsh, cool light; the soft, multi-hued glow of a planetary nebula; the pulsating strobes of a distant pulsar; the reflected light from a massive gas giant’s rings]`. This lighting should create `[e.g., long, dramatic shadows; high-contrast specular highlights on ice crystals; a sense of overwhelming scale; eerie, volumetric god-rays piercing through the gas clouds]`.
**3. Primary Subject: The Comet (Pre-Meltdown State):**
* **Designation & Scale:** A `[e.g., colossal rogue comet, kilometer-wide Oort cloud remnant, ancient Kuiper Belt object]` with a diameter of approximately `[e.g., 5 kilometers, 50 miles, 200 meters]`.
* **Core Composition:** The surface is a craggy, irregular landscape of `[e.g., primordial water ice, frozen methane, and ammonia]`, mixed with `[e.g., dark, carbonaceous chondrite dust, veins of glowing cryo-minerals, metallic silicate compounds]`.
* **Surface Texture & Features:** The texture is `[e.g., heavily cratered and fractured, smooth and almost glassy, porous like pumice stone]`. Visible features include `[e.g., deep, shadowed crevasses; towering spires of ice; active cryogeysers venting faint plumes of gas]`.
**4. Core Action: The Meltdown & Fragmentation Event:**
* **Triggering Event:** The meltdown is initiated by `[e.g., intense radiation from a stellar flare, gravitational tidal stress from a close planetary fly-by, an internal radioactive decay chain reaction, impact from a smaller asteroid]`.
* **Meltdown Process:** The core begins to heat from the inside out. Massive fissures crack across the surface, not with fire, but with `[e.g., brilliant, searing white-hot light escaping from within]`. The meltdown is a `[e.g., slow, agonizing rupture over several minutes; a sudden, cataclysmic explosion; a sustained, violent outgassing event]`.
* **Fragmentation Pattern:** The main body of the comet `[e.g., shatters into a dozen large, tumbling fragments; is vaporized from one side, creating a massive rocket-like thrust; fractures into millions of smaller, glowing shards; melts into a molten, protoplanetary blob]`.
**5. Detailed Fluid & Particle FX Breakdown:**
* **Fluid Dynamics (The “Melt”):**
* **Substance:** The melting ice doesn’t just turn to water. It becomes a superheated, low-gravity fluid of `[e.g., liquid nitrogen and slushy ammonia, glowing plasma-like water vapor, viscous, bubbling cryo-magma]`.
* **Behavior:** The fluid `[e.g., erupts in massive, zero-G spherical plumes; sheets across the surface, flash-boiling into space; forms shimmering, unstable tendrils that connect fragmenting pieces]`.
* **Color & Luminosity:** The fluid has a color palette of `[e.g., electric blues, cyan, and stark white; deep violets and magentas with incandescent orange hotspots; sickly greens and yellows]`. It is `[e.g., self-illuminating, translucent, opaque and boiling]`.
* **Particle Emitters (Debris & Vapor):**
* **Primary Emitter:** The main fissures and impact points violently eject `[e.g., a dense cloud of razor-sharp ice crystals, fine silicate dust that catches the light, glowing embers of superheated rock]`. The particles have a velocity of `[e.g., thousands of kilometers per hour, creating hypersonic shockwaves in the surrounding gas]`.
* **Secondary Emitter:** Sublimating surfaces release `[e.g., a shimmering, effervescent vapor of ionized gas; a thick, foggy cloud of carbon dioxide; sparkling, frost-like micro-crystals]`. This forms a chaotic, rapidly expanding coma around the disintegrating core.
* **Trajectory:** Particle trajectories are a mix of `[e.g., ballistic arcs, chaotic swirls caught in vapor currents, and straight, high-velocity vectors]`.
**6. Artistic Style & Mood:**
* **Overall Style:** `[e.g., Hyper-realistic cinematic VFX, dramatic and painterly like a John Harris painting, abstract and ethereal, high-fidelity scientific visualization]`.
* **Inspirations:** Visuals inspired by `[e.g., Hubble Space Telescope deep-field images, scenes from “Interstellar” or “Gravity,” real-world footage of volcanic eruptions, microscopic crystallography]`.
* **Mood:** The atmosphere should be `[e.g., terrifying and apocalyptic, awe-inspiring and majestic, chaotic and violent, serene yet catastrophic]`.
* **Color Grading:** Apply a final color grade of `[e.g., cold cinematic blues and teals, high-contrast black and brilliant whites, warm nebula tones with cool highlights, desaturated and gritty]`.
**7. Technical Directives:**
* **Camera & Composition:** `[e.g., Extreme wide shot showing immense scale, dynamic close-up tracking a single shattering fragment, slow-motion macro shot of ice crystals sublimating, fisheye lens perspective from the surface of the comet]`.
* **Render Quality:** `[e.g., Photorealistic, 8K resolution, octane render, unreal engine 5, volumetric lighting, ray tracing, high particle count, motion blur]`.
**8. Negative Prompts (What to Avoid):**
* **Exclude:** `[e.g., Fire, smoke, traditional explosions, sound, aliens or ships, overly saturated or cartoony colors, hard-edged geometric shapes, uniform particle distribution]`.
