📝 Step-by-Step Tutorial

Step 1: Execute Character Continuity Master Prompt in Claude AI [Timestamp: 02:17]

Open Claude AI and paste the complete Master Prompt below. Claude acts as a 3D animated film art director and character continuity supervisor, locking in character traits (such as Hugo the blue gecko's amber eyes, brass goggles, leather harness, and satchel) along with supporting character descriptions across 5 sequential scenes in 16:9 landscape format.

Prompt / Settings:

PROMPT / SETTINGS

Act as a professional 3D animated-film art director and character-continuity supervisor.

Generate FIVE SEPARATE finished images for a colorful coastal adventure featuring one consistent blue gecko protagonist. Follow the character descriptions, scene specifications, and visual direction below.

OUTPUT REQUIREMENTS
- Exactly five separate images, generated in the numbered order.
- Landscape 16:9 composition for every image.
- Each image must fill its own canvas.
- Do not combine the scenes into a collage, contact sheet, split screen, or storyboard grid.
- Produce the actual images, not a rewritten set of prompts.
- If only one image can be generated per response, begin with Scene 1 and retain these instructions for the remaining scenes.
- No reference image is required; all necessary visual information is included below.
- Do not render scene numbers, titles, captions, watermarks, logos, timestamps, or interface elements.

OVERALL VISUAL DIRECTION
Use a polished stylized 3D animated-feature aesthetic: appealing rounded characters, oversized expressive eyes, carefully sculpted faces, detailed but gentle skin textures, tactile handmade props, believable cloth and leather, warm cinematic sunlight, soft global illumination, and vibrant Mediterranean scenery.

The world should feel playful, adventurous, and welcoming. Use strong readable silhouettes and clear facial emotions. Keep the main characters sharp, with selective background softness. Avoid photorealistic humans, flat 2D illustration, harsh plastic surfaces, excessive bloom, and muddy shadows.

MAIN CHARACTER — FIXED DESIGN
Name: Hugo. This name identifies the character and must not appear as text in the images.

Hugo is a small, youthful blue gecko with:
- An oversized rounded head and a slim, compact body.
- Cobalt-blue skin with soft violet shading around the temples.
- Subtle turquoise freckles across the forehead and cheeks.
- A pale aqua muzzle, throat, and belly.
- Enormous golden-amber eyes, circular black pupils, and bright white catchlights.
- Rounded expressive brow ridges.
- Two tiny nostrils and a wide flexible mouth.
- No hair, external ears, horns, beard, or mustache.
- Four rounded digits on each hand and foot.
- A long blue tail that naturally curves behind him.
- Antique brass aviator goggles with muted green-gray lenses, resting on his forehead.
- A brown leather goggle strap.
- A weathered brown leather shoulder harness, buckled waist belt, and small brown satchel at his hip.
- No shirt, trousers, or shoes.

Keep his face shape, eye color, skin colors, freckles, body proportions, goggles, harness, and satchel consistent across all five images. Adapt his expression and pose to each scene without redesigning him.

SUPPORTING CHARACTER — REPTILE CHEF
A taller, heavyset teal-blue reptile with:
- A broad rounded head.
- A cream-yellow muzzle and belly.
- Large amber-brown eyes and thick dark eyebrows.
- A prominent ochre handlebar mustache.
- Small blue cheek spots.
- Short rounded dark-blue spines behind the head and along the tail.
- A tall, soft white chef toque.
- An off-white short-sleeved chef shirt.
- A cream apron.
- A red-and-white checked neckerchief tied at the front.
- Two ordinary wooden cooking spoons when required.

He appears in Scenes 1 and 4. Preserve his design between those scenes.

SUPPORTING CHARACTER — OWL
A small, round tan-and-brown owl with a fluffy cream chest, darker brown wings, two short feather tufts, large brown eyes, thick expressive brows, a small hooked brown beak, and tiny orange feet.

It appears in Scenes 1 and 3. In Scene 3 only, add a small brown aviator cap and brass flight goggles above its eyes. Preserve the underlying face, feathers, and body proportions.

SUPPORTING CHARACTER — SEAGULL
A white seagull with gray wings, dark feather tips, an orange-yellow beak, expressive eyes, and thin pink legs. It appears in Scenes 1 and 2.

SUPPORTING CHARACTER — ELDERLY REPTILE
A slim pale yellow-green elderly reptile with a long gentle face, a tall swept-up ivory hair tuft, a beige explorer outfit, and a wooden walking staff topped with a coral-orange spiral. It appears on the cliff in Scene 1.

SUPPORTING CHARACTER — HUMAN CHEF
A stocky middle-aged man with warm tan skin, curly black hair at the sides of his head, thick black eyebrows, a bulbous nose, flushed cheeks, and a large black mustache. He wears a tall white chef toque, a cream double-breasted chef jacket with rolled sleeves, and a blue-and-white checked shoulder towel.

He appears in Scene 2. He is a separate character from the teal reptile chef.

SHARED WORLD
A sunny Mediterranean-inspired island with turquoise water, cream limestone cliffs, lush green vegetation, pastel coastal buildings, terracotta roofs, rustic kitchens, and handmade adventure equipment.

SCENE 1 — THE HOMEMADE GLIDER
Show Hugo launching from a rocky seaside cliff, suspended in the foreground beneath a wide homemade glider.

The glider has curved wooden branch supports tied with coarse rope. Its wings are made from faded slate-blue and rusty-orange fabric patches with obvious stitching, circular repairs, and slightly frayed edges.

Hugo grips the supports, his legs dangling and long tail curling behind him. His mouth is open in delighted laughter.

On a rocky ledge to the right, the elderly reptile, reptile chef, owl, and seagull watch and cheer. The seagull raises its wings.

Use a low, wide-angle view with turquoise ocean and distant limestone sea stacks behind the characters. Warm sunlight should illuminate the wing fabric and cliff.

SCENE 2 — KITCHEN CHAOS
Show Hugo running along a blue-and-white tiled kitchen counter on the left. His head turns back toward an angry human chef on the right. A small bundle of brass mechanical parts and old keys is attached to Hugo’s harness.

The human chef raises a wooden spoon and holds a small metal mesh strainer in his other hand. His mouth is open in comic outrage.

The seagull flies through an open shuttered window carrying a cream recipe sheet in its beak. Additional sheets float through the room.

Include copper cookware hanging overhead, garlic bulbs, red chilies, dried herbs, a white farmhouse sink, brass faucet, ceramic jug, and an open recipe book on a wooden stand. Recipe pages contain only indistinct marks.

Bright coastal daylight enters through the window, with pastel buildings and blue water visible outside.

SCENE 3 — FLIGHT ABOVE THE COAST
Show Hugo piloting a vintage handmade open-cockpit aircraft. He grips a circular metal steering wheel and laughs with excitement.

Behind him, the owl spreads its wings and looks terrified, gripping the cockpit rim with its feet. It wears its small aviator cap and goggles.

The aircraft has a weathered silver-gray riveted fuselage, dark leather cockpit edging, two open seats, faded coral-red wings and tail surfaces, exposed fasteners, and a little pale hanging charm.

Use a close three-quarter camera angle from ahead of the front cockpit, looking back at both passengers. Place the aircraft diagonally as it banks over turquoise water, tall cream cliffs, white houses, terracotta roofs, and green trees.

SCENE 4 — THE AIRBORNE CHEF
Show Hugo close to the viewer on the left, airborne with arms spread, satchel swinging, and an enthusiastic smile.

The heavyset teal reptile chef is on the right, also airborne, mouth wide open in comic alarm. He holds one wooden spoon high and the second across his waist. His checked neckerchief, white hat, cream apron, and curved tail must remain recognizable.

A blue sky dominates the background, with a golden limestone cliff at the far left. Three tiny blue gecko companions appear far behind them, without Hugo’s goggles or satchel.

Use a slightly low-angle close composition, sharp foreground expressions, bright sunlight, and playful action.

SCENE 5 — THE CLIFFSIDE CONTROLLER
Show Hugo from the chest upward on the right side of the frame, standing at a sheltered rocky overlook. He smiles gently toward the viewer.

He holds an aged brown mechanical controller with a brass top plate, small screws, narrow slots, and two short brass levers. One hand grips a lever while the other steadies the box. No digital display.

Below on the left, show a green soccer stadium with white field markings, small goals, tiny blue reptile players, stands packed with small blue spectators, colorful pennants, and a low pavilion with a tan roof.

Beyond it, include a pastel seaside town, terracotta rooftops, lush vegetation, cream limestone cliffs, a harbor, and brilliant turquoise ocean.

Frame the upper corners with warm rock edges. Use late-afternoon golden light, a sharp foreground face, and a detailed but gently softened distant landscape.

FINAL CONTINUITY CHECK
Before completing each image, check:
- Hugo has the same face, amber eyes, blue skin, aqua belly, goggles, harness, and satchel.
- Supporting characters match their established descriptions.
- No additional main characters have been introduced.
- Hands, feet, wings, tails, and props are clearly separated.
- Goggles rest on Hugo’s forehead in every scene.
- Each image depicts one clear moment.
- There are no duplicate foreground characters, extra limbs, fused objects, illegible text overlays, or screenshot artifacts.
- All five images share the same polished 3D rendering style and coastal world.

Step 2: Render 3D Stylized Frames in Google Flow [Timestamp: 03:08]

Navigate to Google Flow and select the image creation canvas. Choose the Nano Banana 2.1 model and set the aspect ratio to 16:9. Copy the Scene 1 prompt generated by Claude AI, paste it into the prompt box, and generate. Repeat the process sequentially for the remaining scenes to produce consistent, high-resolution 3D character images.

PROMPT / SETTINGS

Smooth cinematic 3D animation. The character laughs with delight as the glider sways in the coastal breeze, legs dangling playfully. Gentle cinematic camera push-in with soft background parallax over the sunny coastal ocean.
Aspect Ratio: 16:9

Step 5: Generate Sequential Clips and Verify Consistency [Timestamp: 06:51]

Repeat the video generation process for each subsequent scene in Dola AI. When the renders complete, review character silhouette integrity, prop stability (goggles and harness), and camera movements across all scenes before stitching the final animated story together.

💡 Key Takeaways & Pro Tips

Anchor Fixed Visual Motifs: Retaining identical signature accessories (like antique brass goggles and leather harness) across prompts is critical for preventing AI character redesigns between different camera angles.
Action-First Video Prompts: Always specify character expressions, secondary movement (flapping wings, hair, cloth), and specific camera movements in video prompts to prevent static outputs.
Sequential Generation: Generate base scene images one by one and verify costume details before running motion generation tools.
