A starting point for something great
Use these source-backed 3D prompts as references, adapt them, and try the same idea across GPT-6 Astra, Claude, Kimi or any model you use.
Build an explorable Manhattan world in Unreal Engine. Work district by district and street by street, preserving recognizable scale, road layout, landmarks, traffic and neighborhood character; keep an evaluation checklist and refine each area before moving on.
Build a kaiju-inspired Three.js game using generated creature models and sound effects. Create readable giant-scale combat and an environment that communicates the size of the creatures.
Set up expression variants of a Tripo character in Blender before rigging. Align the meshes and switch them discretely, shrinking inactive variants inside the head. Do not imply smooth blending or VRM compatibility.
Build a playable Minecraft-inspired voxel world in one pass with terrain generation, block placing and breaking, first-person controls, inventory, lighting, water and a compact survival loop.
Create an Unreal Engine world populated by autonomous human agents. Give them individual needs and a shared survival goal so they must communicate, divide work, build shelter and keep the society alive when the player leaves.
Build a complete modern villa scene in Blender with coherent architecture, furnished interiors, an infinity pool, landscaping, realistic materials and a cinematic golden-hour camera path.
Create a complete 3D game that runs in the browser in one self-contained project. Include a readable objective, responsive controls, spatially coherent levels, enemies or hazards, feedback, scoring, restart and performance safeguards.
Recreate San Francisco’s Palace of Fine Arts in Blender with recognizable rotunda proportions, colonnades, lagoon, vegetation, weathered materials and optimistic world-fair-era cinematic lighting.
Reconstruct the supplied house image as a fully editable Blender scene. Model the architecture plus furniture, appliances and toys as separate objects, preserve plausible proportions and make the result run locally as a smooth 60 FPS walkthrough.
Use the supplied real-estate listing and all listing photos to reconstruct the house in 3D, infer a coherent floor plan, then create a polished promotional walkthrough video. Flag uncertain geometry and refine mismatches after the first pass.
Translate a set-design description of the Oval Office into executable scene code, build the location in Blender with editable furniture, walls, lighting and camera blocking, then render a cinematic result with Cycles.
Create a delicious-looking bouncy jelly using Three.js and WebGPU. Make it deform and settle naturally after interaction, with translucent material and readable lighting.
Build a playable real-time 3D game from one prompt. Define a compact core mechanic, a clear objective and short story, then generate the scene, characters, props, feedback and restart state so the result can be played immediately.
Reconstruct the supplied vintage steam-train drawing in Blender as a detailed mechanical assembly. Keep wheels, axles, suspension, rods, boiler fittings and body panels as named editable objects, with a controllable detail budget.
Build an AAA-quality kart racing game in Three.js with polished driving, expressive tracks, opponents, items, UI, sound and a complete playable race loop.
Create a detailed Three.js forest with thousands of trees, dense grass and ferns. Use custom shaders and efficient repeated geometry to preserve detail across the scene.
Create a glass aquarium whose side panel develops a visible crack and then bursts.
Design an explorable futuristic mansion on a private island, presented through five connected Three.js scenes with cinematic camera movement, premium materials and environmental storytelling.
Create a 3D website that pulls a Tesla Model X apart into modeled components. Let visitors inspect the assemblies and reassemble the vehicle interactively.
Generate two trains directly in Three.js from dimensions, profiles and geometry functions. Animate wheels and provide an exploded-view and reassembly sequence.
Take the supplied Unity kart-racing greybox and produce three playable themed variants: pirate, candy and cyberpunk. Reuse the core driving loop, replace environments and feedback, play-test each build and fix the most visible bugs.
Recreate Terreiro do Paço in Lisbon as an editable Blender scene. Use reference research to guide the square's architecture, materials and lighting.
Use the supplied reference image to build a complete 3D aquarium game in a single pass. Reconstruct the tank composition, animate fish, add feeding and collection interactions, water effects, camera controls and a clear objective.
Use the supplied floor plan to create an accurate Blender 3D model, render a set of representative still images and produce a coherent walkthrough video.
