We build a 3D generation product, so we run other people's 3D generators the way a chef eats at restaurants: constantly, critically, and with strong opinions afterward. This post is the write-up we wished existed when we picked our own stack. It covers the three hosted engines most people shortlist (Tripo, Meshy, Rodin) plus the open source route, and it spends most of its words on the two things demo videos never show: who actually owns the output, and what happens when you import it into Blender.
One caveat up front. We work at Trify3D, so treat our taste in engines accordingly. The pricing and license facts below are pulled from each vendor's own pricing page on October 12, 2026, with links, so you can verify every number instead of trusting us.
How we tested: same prompt, three engines, real exports
Google's own AI summary of this topic sorts the field by use case: Tripo for beginners, Meshy as the all-rounder, Rodin for game assets. That framing is fine as far as it goes. It also tells you nothing about what happens after the fun part.
Our method was duller than that. We take one prompt family (stylized props and characters, the kind of asset that ends up in a game or a print), run it through each engine, export the result, and open it in Blender. A model that looks great in a web viewer but arrives as a shader mess in Blender has failed, as far as we are concerned. The scoring axes:
- What the free tier actually gives you, in credits and in rights
- What commercial use costs once you are paying
- Export formats, and how much cleanup the mesh needs
The last point is where most comparisons go quiet, so we will not.
Quick answer: which generator fits your use case
If you want to sell what you make on a zero budget, Meshy is the pick, because its free tier licenses outputs under CC BY 4.0, which allows commercial use with attribution. If you want to pay per asset instead of per month, Rodin's pay-by-result model at $1.5 per credit is the closest thing to a meter. If you are brand new and just want the friendliest editor, Tripo. If you can run your own GPU, Microsoft's TRELLIS ships under an MIT license, which is the least restrictive option on this page.
That is the short version. The table below is the version that matters.
Pricing and license table (the part nobody shows you)
Prices and terms from each vendor's pricing page, checked October 12, 2026:
| Platform | Free tier commercial use? | Conditions | Cheapest paid commercial tier |
|---|---|---|---|
| Tripo | No. Free outputs are marked "Non-Commercial Use" | Free models are public | Pro $20/mo, 3000 credits (~200 models) |
| Meshy | Yes | CC BY 4.0, you must attribute | Pro HK$170/mo, 1000 credits |
| Rodin | Not stated on free tier | Free tier gives 10 private assets | $24/mo, "Commercial license included" |
Three companies, three completely different answers to the same question. Most listicles bury this in a footnote. We think it is the whole decision.
Tripo: easiest start, but watch the free tier license
Tripo deserves its reputation as the beginner's option. The editor is clean, generation is quick, and the credit math is simple: the free plan includes 200 credits, which works out to roughly 13 models, and each generation shows up in a public gallery. If you are learning what AI 3D generation can and cannot do, that is a fine place to burn zero dollars.
The catch sits in the license line. Free tier outputs are "Public Models, Non-Commercial Use." We have not seen another major hosted engine state it that bluntly. The practical meaning: anything you generate before paying belongs to the practice pile. Sell a print of a free-tier dragon and you are outside the terms.
Paying changes the picture. Pro runs $20 a month for 3000 credits, about 200 models, which lands near $0.16 per model. Their larger tiers push the per-model cost down toward $0.09. For a hobbyist who outgrows the free tier, $20 is a reasonable step up, and commercial use is explicitly included from that tier onward.
Who we would hand Tripo to: someone in their first week, or a studio that values speed over everything and will pay from day one. Who we would not: a broke indie planning to monetize free-tier output. That plan does not exist here.
Meshy: the only free tier that lets you sell what you make
Here is the fact that separates Meshy from the pack, and the one almost no comparison page leads with. The free plan's outputs carry a CC BY 4.0 license. That is a real, standard, commercial-friendly license: use the model in a paid game, print it and sell it, whatever, as long as you credit Meshy. Attribution on a loading screen or a product page is a small price when your budget is zero.
We generate stylized characters constantly, and this is the tier we point students and jam participants toward. A chibi archer or an anime-style maid made on Meshy's free plan can ship in a jam project with attribution and stay legal. On Tripo the same asset would need a paid plan first.
The paid tiers scale by credits, quoted here in HKD since that is the region our account landed in: Pro at HK$170 per month for 1000 credits (roughly 100 assets), Premium at HK$340 for 3000, Ultra at HK$850 for 8000. Paid plans switch you to a private, commercial license and drop the attribution requirement.
Meshy also ships a DCC bridge covering Roblox, Blender, Godot, Unity, Unreal, Maya, and 3ds Max, which tells you who their customer is. For game workflows this is a genuine convenience. It does not save you from the mesh cleanup every engine's output needs, which brings us to the section most articles skip.
Rodin: pay for what you keep
Rodin, from Hyper3D, prices unlike anyone else here. The free plan is $0 and works on a confirm-the-result model: you generate, you inspect, and direct credits cost $1.5 each, with the free workflow letting you generate before you commit. The workspace holds 10 private assets on the free tier, and publishing to the public gallery is available.
For someone who needs three good assets a month, this is the cheapest honest option on the page. Subscriptions assume volume; Rodin assumes you might not.
One thing we could not verify: whether free-tier outputs carry commercial rights. Rodin's pricing page does not state it for the free plan, and their paid tiers say "Commercial license included" starting at $24 a month (about 60 models at the yearly rate). Since the page is silent, we treat free-tier commercial use as unknown, not as a yes. Check with them before you ship anything commercial made on the free plan. If they confirm it in writing, Rodin jumps a tier in our recommendation, because the pricing model suits low-volume users better than anyone else's.
Open source options: free is not the same as unrestricted
Both big open source names look identical from a distance and could not be more different in the fine print.
Tencent's Hunyuan3D-2 has 15.1k stars on GitHub and a serious research pedigree (the 2.0 paper is on arXiv, 2506.16504, if you want the architecture details). The license is where people get burned. It is a custom Tencent license, and two clauses matter. First, it does not apply in the European Union, the United Kingdom, or South Korea at all. Second, if your product exceeds 1 million monthly active users, you must request a separate license from Tencent, which they may decline. For an EU-based indie, running Hunyuan3D-2 commercially is not a gray area. It is off the table.
Microsoft's TRELLIS (13.9k stars, the Structured 3D Latents paper, a CVPR 2025 Spotlight) ships under plain MIT. Run it commercially, fork it, embed it in your product, no permission letter needed. Between the two, the choice is not technical. It is jurisdictional.
The trade you accept with both: you provide the GPU, the environment, and the patience. Self-hosting a diffusion model is a weekend project for an ML engineer and a lost month for everyone else.
Getting AI models into Blender: what breaks and why
This is the section we could not find anywhere in the top results, and it is where most people's AI 3D workflow actually dies.
The export from every hosted engine here is usually OBJ or GLB. OBJ is the lowest common denominator, and Blender's own manual is refreshingly blunt about it: the format has "only basic geometry and material support," with no support for armatures, lights, cameras, empty objects, parenting, or transformations. Translation: the anime character you generated has no rig. The textured prop may arrive with its textures detached or half-applied, because OBJ material support tops out well below what the web viewer showed you.
What we do, in order:
- Prefer GLB over OBJ whenever the engine offers it. More of the material data survives the trip.
- Expect to re-do materials in Blender for anything hero-quality. Generated textures are a starting point, not a finish line.
- Rigging is always manual. No hosted engine here outputs a production-ready armature. Plan for it or stick to static props.
None of this is a flaw in Blender. It is the gap between a demo viewer and a production tool, and it exists for every engine on this list. Budget an afternoon of cleanup per hero asset and the disappointment mostly disappears.
How to choose without wasting credits
Decide with these, in order:
- Will you sell the output while paying nothing? Only Meshy's CC BY 4.0 tier says yes today.
- Do you need fewer than ten assets a month? Rodin's pay-per-credit model beats every subscription.
- Are you a first-timer who just wants to poke around? Tripo, and treat free-tier output as practice.
- Can you run your own GPU and need zero restrictions? TRELLIS, MIT license. EU or UK team? TRELLIS is your only open source option here anyway, since Hunyuan3D-2's license excludes your region.
One warning that applies to all three subscriptions: credits burn on failures and rerolls as fast as on keepers. A generation you discard costs the same as one you keep on most plans. Rodin's confirm-first flow is the exception, which is exactly why it fits low-volume users.
What we would pick today
For a hobbyist selling prints on a zero budget: Meshy free, attribution included in every listing. For a small studio shipping a game: Meshy Pro or Tripo Pro, decided by which editor your artists prefer after a week of real use. For occasional needs: Rodin, confirm-first, $1.5 a credit. For infrastructure teams: TRELLIS, self-hosted, MIT.
The honest summary of six months of daily use: the "best AI 3D model generator" question has a boring answer. It is decided by license terms and export formats, not by leaderboard screenshots. Read the pricing page's license line before you generate anything you plan to sell. Then open the result in Blender before you commit to a plan, because that is where the real work starts.
