Built with Blender

After a third round of refinement with Opus 5.5 at medium (middle reasoning setting), Blender (a 3D program), an image-generation AI and three.js (a web 3D tool) were combined into a game that runs directly in the browser. The screen shows a character standing on a skyscraper rooftop and a small map at the bottom right.

Making a game used to mean moving between many tools. One model stitched them together into a result you can open without installing anything.

Alongside GPT-6 Astra, it was asked to make five games, each from a single prompt: a 2D platformer, a racing game, spaceship combat, a first-person shooter and a stone golem boss fight. No human wrote a single line of code. The 3D assets (the character and object models in the games) were not downloaded. All of them were made from scratch in Blender (a 3D creation program).

It shows that five games in different genres can be filled out with one request each, from model building to graphics, sound and game rules.

After a single request in the claude.ai chat, Opus 5.5 operated the 3D program Blender directly and made an animation that looks like a clay puppet show.

Even someone who has never opened a 3D program can go from modeling to rendering in one conversation.

From a single prompt, it recreated San Francisco's Market Street just before the great 1906 earthquake in Blender.

It goes beyond a single building and builds a whole street that is accurate to the period.

Connected to Higgsfield's tools, Opus 5.5 modeled a Shinkansen train in Blender. It built the train from 5,112 separate objects, and each of the 430 cabin seats is its own object.

It does not stop at the exterior. The model fills in the inside of the train too.

From one photo of a house and a floor plan, it built a Blender 3D model and a web viewer to explore it. You can view the house by construction stage, see through walls and walk around the furnished interior.

It builds the 3D model and writes the program that uses it in one continuous run.

Opus 5.5 was given the rigging (placing a skeleton so a model can move) and animation of a monster model in the 3D program Blender. It finished in 40 minutes, jump and bite moves included. GPT-6 Astra took 65 minutes on the same job.

Game character animation that people used to do by hand can now be handed to the model and used in real game development.

A casual game where you are a pressure washer, cleaning dirty floors while avoiding flower beds, cars and cats. The 3D models were prepared with Blender and Tripo (an AI tool that makes 3D models from text or images), and the game was written with Rust, Wasm (a code format that runs fast in the browser) and WebGPU (a technology for using the graphics card from the browser). It plays right away in a phone browser too.

An individual developer working with Opus 5.5 can release a 3D game built with a demanding language and the latest graphics technology, playable by anyone from a single link.

After one request on claude.ai, Opus 5.5 used the 3D program Blender to make a short clay animation. It shows the motor protein kinesin (a protein that carries cargo inside cells) walking along a microtubule (a thin tube that acts as a road inside the cell), with subtitles.

Researchers can turn movement inside cells, once seen only in textbook drawings, into an explainer video with a single prompt.

From a single short prompt, Opus 5.5 made a sand art animation (pictures drawn by scattering and sweeping sand). It added the voice and sound effects itself, without the 3D program Blender or the web 3D tool Three.js, and the result was never edited.

A short video with drawing, voice and sound can come from a single request, with no video tools.

Opus 5.5 was given a gaming laptop, the Unity game engine, the 3D program Blender and external APIs, and left to work on its own for 36 hours. The result was a playable old-school MMO RPG (a role-playing game where many players share one world online). It used 7.85 billion tokens and cost $2,175 for Opus 5.5. A separate $230 went to 2D and 3D art and music generation.

One person can build a game, down to a character creation screen where you pick a race and class, on a single laptop in under two days.

Given 4 reference images and a first prompt, Opus 5.5 built a 3D roguelite on a 6×6 chessboard by itself, using the Godot engine in Claude Code (a game where you pick a new path each round and grow your pieces). The game code, the 3D models of the chess pieces and arena, and the music and sound effects were all made in code, with no Blender or asset files.

A person can finish a whole game, with graphics, sound and rules, without writing a single line of code.
