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.
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 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 a mobile game advertisement as reference to build a playable browser game. Recreate its central interaction and use Blender assets to match the visual premise.
Build a mobile-first 15-second interactive demo of [product]. Let the user try the core feature with one gesture, give immediate 3D feedback and end with a clear “Get full access” CTA. Use a vertical 9:16 layout and preserve brand colors.
Act as my 3D game builder. Ask only for the missing player goal, art direction and controls, then create a browser game I can play immediately and keep revising it from short voice instructions.
Build an inspectable PlayStation 5 controller in Three.js with a recognizable silhouette, buttons, triggers, analog sticks and distinct surface materials.

YouTube ↗Why this collection
Looking for Astra prompts you can actually build from? Start with a 3D example that matches your task: a Blender model, a Three.js website, a browser game or an explorable world. Each entry pairs a visual result with an author, a source link and a prompt or a clearly identified source-derived brief.
A useful Astra 3D prompt defines what to make, which software to use, what should remain editable and how to check the result. Copy a starting point, change the subject and constraints, then test the same brief with GPT-6 Astra or another model. These are references to adapt, not a guarantee that one prompt reproduces an entire demo.
Best for
01
For an Astra Blender prompt, name the objects, materials, lighting and camera. Ask for separate editable objects and a saved scene, then inspect the render from more than one angle.
02
For an Astra Three.js prompt, describe the scene, mouse and touch controls, loading behavior and a target device. Include a playable loop when making a browser game.
03
Use the Unreal Engine and Unity examples to plan explorable worlds. Specify scale, collisions, camera movement and the files you need; a showcase video alone does not prove a project is ready to ship.
Prompt recipe
State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.
Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.
For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.
Give your next scene a character worth a closer look. Create detailed, textured 3D assets from an image or a few words.
Generate 3D Assets FreeNo. Every entry is labeled. “Verbatim” preserves wording published by the author; “source-derived brief” is a reusable prompt reconstructed from the public demo description. We do not claim access to prompts that were never published.
Use them as references, not model-specific magic words. Keep the outcome and acceptance checks, then adapt the tool, asset budget, camera, controls and output format for Astra, Claude, Kimi or another model.
Use the With GitHub filter to find Astra 3D examples with public code, then open an example for its repository and available live demo. The open-source collection brings these projects together across models. Check each repository’s license and setup instructions before reuse.
