The author shared part of the prompt.
Claude Opus 5.5 is absurdly good at 3D. I reran one of my recent 3D experiments with Claude Opus 5.5. Same prompt, same references, same real-world scene I had previously built with GPT-6 Astra. The result was much better than I expected. Put simply, for this specific use case, Claude Opus 5.5 was a clear win for me. The biggest differences for me were instruction following and taste. With the same references, Opus 5.5 got much closer to the Zelda Breath of the Wild-style look I was aiming for. The layout felt more intentional. It picked better camera angles. Asset placement made more sense. And I spent much less time fixing basic mistakes. In my Astra version, I had to repeatedly correct things like tree roots not touching the ground, rough geometry being used where proper assets already existed, or objects being placed in ways that just looked wrong. Opus 5.5 got much more of this right on its own. The interesting part for me is that I have almost zero real 3D skills. I mostly give references, look at the result, explain what feels wrong, and keep iterating. With better instruction following and visual judgment, that loop becomes dramatically easier. Still plenty to improve, especially indoors. Next test is whether I can recreate the interior of the house with the same level of quality.
3D scenes0:35Opus 5.5 does a great job in eval of GLSL (OpenGL Shading Language) in threejs.
The prompt here is roughly. A fishbowl with reflection, refraction and water caustics.

3D scenes0:37Opus 5.5 turned one sentence into a 3D system that opens in Blender, rigged, textured and ready to animate.
It does not render the object. It constructs it, part by part, the way a modeller would if they had a week.
> PARSE - the sentence becomes a parts list with real dimensions, nothing implied
> MASS - each part built as clean geometry, quads only, no sculpted mush
> RIG - joints and pivots placed where the object physically bends
> SKIN - materials assigned per surface, scale and roughness set separately
> PACK - exported with a named hierarchy, so a human can edit one part

3D scenes0:42Esta app probó 3,932 posiciones de una cama matrimonial hasta encontrar dónde cabe.
La hizo Claude Opus 5.5 con un prompt mío: cuarto de 3.00 x 3.40 m, puerta de 80 cm, un clóset de 1.20 x 0.60 y la cama de 1.40 x 1.90.
Armó el plano a escala y el cuarto en 3D al lado, y los dos se mueven juntos.
Si la cama choca con el clóset, no deja abrir la puerta o te deja menos de 60 cm para pasar, te avisa.
Solo 108 posiciones no tenían ningún problema. La mejor deja 70 cm para pasar por cada lado.
Tardó 47 minutos, más 5 para pasarla a inglés, y no le corregí nada.
Para una mudanza, esto dice más…
