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 and 3d models than to just make your own.

Either AI can oneshot without human intervention or it becomes a pain really quickly

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.

>We've seen this with photogrammetry before.

Have we? It's still not that good.

Somehow this article explains perfectly, visually, how AI generated code differs from human generated code as well. You see the exact same patterns. AI uses more code to accomplish the same thing, less efficiently. I'm not even an AI hater. It's just a fact. The human then has to go through and cleanup that code if you want to deliver a high-quality product. Similarly, you can slap that AI generated 3D model right in…

"High-quality code can be a joy to extend and build upon." I love the analogy here. It is a perfect parallel to how a good 3D model is a delight to extend. Some of the better modelers we've worked with return a model that is so incredibly lightweight, easily modifiable, and looks like the real thing that I am amazed each time.

The good thing about 3D slop vs. code slop is that it is so much easier to spot at first glance. A sloppy model immediately looks sloppy to nearly any untrained eye. But on closer look at the mesh, UVs, and texture, a trained eye is able to spot just how sloppy it truly is. Whereas with code, the untrained eye will have no idea how bad that code truly is. And as we all know now, this is creating an insane amount of security vulnerabilities in production.

Earlier quoted context omitted.

Such as?

Luma, Rodin, Tripo are a few. Meshy has some of these features too Unfortunately they are all proprietary, but 3D models are sort of a side area in AI research, so most of the effort is from small startups.

In no capacity do these create clean topo, textures, and uvs. If you do not believe me, use the reference image from the post and upload it to Meshy or Tripo and see what happens. Yes, slightly better than the open source Trellis, but still nearly impossible to work with and a model you would never put on any slightly serious eCommerce site.

We've tried them all. If one existed, it would save us money, speed up our pipeline, and trust me we'd be using it.

Touché. Though if the current 'eCommerce Standard' is 'dropshipped junk that looks slightly better than a hallucination,' then I’ll happily die on the hill of being over-confident.

"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 functional DNA required for a production environment.

"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 - unusable slop for most use cases.

And it hasn't? Will Smith spaghetti video was exactly three years ago.

It's not fully automated where you come up with a bunch of photos and have production assets. Never has been. It serves its purpose though, so will this if it's not already.

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 painless though.
