Generate 3D Assets FreeLet’s create a game called Mini World. It’s a 3D world exploration game with a beautiful, high-quality graphic interface, designed to be fun and easy to play for my four-and-a-half-year-old son. You should be able to zoom in and zoom out. From far away, the world looks like a small ball, but inside it has different regions to explore. One region can look like a forest, another can be a desert, and there can also be oceans where the character can swim around. The game has to feel fun and playable, with a character who can travel around different parts of the world, explore different environments, and discover things along the way. Please treat making this work properly as the main goal. It should be beautifully designed and thoroughly tested in a loop so that the movement, zooming, exploration, swimming, environments, controls, and overall experience all work smoothly together. Keep testing and improving it until everything is working reliably and the game feels polished, intuitive, and enjoyable for a young child.
Prompt breakdown
Explore “Mini World 3D exploration game”, a GPT-6 Astra 3D example about 3D game, world exploration, spherical world. Check the evidence label to see whether the text is an original prompt or a brief adapted from the public source.
Keep the core outcome, then specify the camera, controls, lighting and what a successful result should do. Test that first before adding more visual detail.
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.
Your prompt builds the game or scene. Bring it to life with more detailed characters and props, created in Tripo to replace simple placeholder models.
A reusable task brief reconstructed from the author’s public project description. It is not presented as a verbatim hidden prompt.
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.
