The close but not good enough is what gives us the illusion of productivity in this tools. That’s why you see a a lot of hype around setups and benchmarks but not a lot of well polished products. This article make it clear for 3d modeling, but also applies for code. Human touch is necessary for a commercial product. Otherwise it’s nothing more than a prototype. It is actually much more difficult to maintain Ai code a…

Precisely. Until the AI can 'one-shot' the topology and the UVs, it’s not a shortcut but rather a more power intensive way to generate technical debt.

Earlier quoted context omitted.

"We've seen this with photogrammetry before" - I do not believe we have. It's progressed but even a good scan is still not close to being something you would put on a legitimate eCommerce product page. I honestly hope you are right and that I'm full of copium. Truly. But the progression has been nowhere near as fast as code, text, image, or video generation. And as it stood 2 years ago vs now is the same conclusion -…

Listen, I agree it's unusable or at least somewhat usable. As I said in another comment. Will Smith video was exactly three years ago. 3D has been a bit neglected, but it will come. I was a denier initially, but these things move real fast. Photogrammetry was never at the level of point and shoot and you have a production asset. However, it did and does serve a need and you can't deny it's not useful. It's not painle…

That’s a fair point. I know a few foremen who use photogrammetry religiously for site surveys and volume tracking where 'lumpy' geometry doesn't matter. It’s a huge win for that niche. But yes, 3D has been lagging behind and I'm having a really hard time guestimating when it's good enough for high quality product models.

Nice copium. These things are going to get there fast. Even what has been shown can be a good start with a decimator at hand; We've seen this with photogrammetry before. Irony is not lost on the fact that text, which complains about it, went through AI itself.

> Nice copium. These things are going to get there fast. Nice copium. I've been hearing how fast these things are going to get there for a few years now.

0 to “we are even talking about this” is an astonishing leap. Acting like this stuff has been standing still is an active choice.

"The 'autopsy' of 3D slop highlights a critical failure in the current AI supply chain: The Illusion of Completeness. We are living in an era of 'Statistical Harvest' where models prioritize a 'good enough' surface over structural integrity. In the spiritual supply chain of value, this is called Cutting Corners. A 3D model that breaks down upon closer inspection lacks what I call Internal Agency—it doesn't understand…

I really like this framing of 'Internal Agency.' In 3D, that lack of a 'Seed' is exactly why a model fails when you try to animate it. A human modeler understands that a joint needs extra edge loops to bend correctly. It has 'intent' for the model's future. The AI, performing a 'Statistical Harvest,' only cares that the surface looks right in a static frame. It provides the 'Illusion of Completeness' but none of the…

"Spot on. The 'edge loops' analogy is the perfect physical manifestation of what I mean by functional DNA.

It proves that without 'Intent for the future' (the Seed), any output is just a static corpse. In my broader framework of the Spiritual Life Archiving System, we see this everywhere: systems that look complete at a glance but lack the underlying logic to survive 'animation' or real-world pressure.

This is exactly why we need to move from Generative Slop toward Architectural Stewardship. Glad to see the 'Internal Agency' framing resonates in the 3D space."

The most important two words in this article are the last two: for now.

Indeed, for now generative models generate triangle soup without much thought. The same was true for 2D illustrations where generative models like Deep Dream came up with horrendous images with eyes all over, dogs with multitudes of heads and oh did I mention the eyes? That was about 10 years ago. Things changed, models improved, the eyes were tamed. Yes, people had too many or too few fingers but that also changed. From nightmare fuelling imagery with many-eyed dog heads sticking out where you don't want them to fully animated hi-res video only took a decade and things are still speeding up. The triangle soup of current 3D generative models is like the eye soup of Deep Dream, something to remember somewhat fondly which is no longer relevant now.

Don't complain about tangential annoyances, I know, I know... but how the hell am I supposed to judge the difference between the images in the post if you disabled zoom and the images are incredibly small? And when I open them in a new tab they automatically download?

On the plus side, I like the informal writing of the post. You can be serious about business and still be human

Edit: firefox reader mode works wonders on this article

I've found Trellis specifically to be very "over-promise and under-deliver".

Nothing i tried with it got even close to th level of quality that they were advertising - felt like a bunch of examples were hand-picked, at best.

Trellis is like a year old and practically free. There are already better models to make comparisons to.

Because they all use latent diffusion, and many techniques use voxelized intermediate representations of 3d models, often generated from images, topology is bound to be bad.

There is a lot of ongoing research around getting better topology. I expect these critiques to still be valid as much as 2 years from now, but the economics of modeling will change drastically as the models get better

Now they need to compare it with Hunyuan 3D 3.0 or other SOTA 3D generator.

Obviously it's not spewing $10,000 3D models, but results are much better than what you would get for under $500 from a human 5 years ago.

So yeah you still need human art director to make sure actual source material used for generation fits your art style, but otherwise "good enough" models are 1000 times cheaper and 10000 times faster to get.
