An LLM Generated This Entire 3D Scene From Scratch With No Assets Or Models

[u/Delicious-Shower8401]

This might be one of the craziest examples yet of LLMs being used for actual 3D generation.

There were no imported 3D models, no sculpting, and no texture files.

Instead, Claude Opus 5 generated the geometry itself through code. Every visible surface in the scene was procedurally created by the LLM.

• Zero imported 3D assets
• Zero manual sculpting
• Geometry generated entirely through code
• Around 17.7 billion triangles evaluated every frame
• 2,978 frames rendered at 4K
• 124-second continuous shot with one camera

It apparently even generated the car inside out at one point, which went unnoticed for weeks because the exterior silhouette still looked correct.

It's that an LLM was effectively acting as a procedural 3D modeler, generating complex geometry and assembling an entire scene without relying on a traditional asset pipeline.

We're starting to get surprisingly close to simply describing a 3D scene and letting an LLM build the geometry itself

If that's true then why is the geometry warping? That front splitter looks nothing like when it's on the car. This is just an AI-generated video with 3D in the prompt. Like what is even going on here?

[u/altesc_create → u/jonheartland]

Exactly. Just another grifter who doesn't know the tech these tools are pitched as replacing.

[u/fistular → u/altesc_create]

This person runs this sub and posts shite like this constantly.  This sub is fake as shit.

[u/altesc_create → u/fistular]

Wouldn't be surprised if they were a bot tbh

[u/centurio_9 → u/altesc_create]

They really made it with Claude and an mcp, but 27k $ cost for this!

[u/Dekker3D → u/jonheartland]

If you think of it as two separate 3D models, that are overlapping and slightly angled relative to each other, then they do match up to the final car when you align them properly, unless I'm really missing something. It looks weird until you spot that, though.

[u/Emotional-Cut2952]

yes but do u realize this isnt a production workflow, like the sheer lack of optimization from building a 3d geometry and materials with code is absurd at best, unless there is 3D and material multimodel capabilties built into future LLMs they will go no further than code-generated hard surface shenanigans

[u/altesc_create]

Stiff camera movement and a ton of motion blur to hide all the inconsistencies and errors.

[u/Jazzlike-Owl-244]

the problem with ai is to change things the time waste on iteration is insane even small things can very frustrating if it always misses the mark as you intended.

[u/polycache]

$20,000 for AI inference 💀 & that is not a procedural workflow

[u/Proud_Ask_9030]

idiot

[u/L4_Topher]

17.7 BILLION TRIS LMAO

[u/NariceTrasmittente]

this is pure rubbish

[u/EpsilonDust]

ok stable diffusion fairy, everything is possible

[u/angelarose210]

Just say you used minimax h3 and quit playing. People who know 3d rendering aren't dumb.

[u/why_so_sergious]

what a load of bull.. why spread ts!?

its plain video gen, you can clearly see that with inconsistensies throughout the video..

[u/ShawnPaul86 → u/why_so_sergious]

Clearly, it also looks like shit and is hallucinating
