PolyMedium vs Meshy: AI 3D Asset Generators Compared
Updated August 30, 2026 · Published August 29, 2026
PolyMedium and Meshy both generate 3D models with PBR materials, and they sit on opposite sides of two real trade-offs: scan-faithful versus prior-heavy reconstruction, and per-model pricing versus a subscription. Here's a structured comparison.
Feature comparison
| Feature | PolyMedium | Meshy |
|---|---|---|
| Image-to-3D | Yes | Yes |
| PBR textures | Yes, baked | Yes |
| Subject-tuned pipeline | Yes, auto-detected: character / object / doodle | General |
| Reconstruction style | Scan-faithful: reproduces the geometry in your reference | Prior-heavy: leans on learned shape priors, strong on organic characters |
| Multi-view reconstruction | Yes, the $0.25 object draft synthesises the unseen side | Multi-image upload optional |
| Rig & animate | No | Yes, separate step |
| Primary export | GLB, USDZ, STL, GIF (FBX and OBJ cloud-converted) | GLB + FBX + OBJ + USDZ |
| Billing | Per model from a prepaid wallet, $0.25 to $3.00 by subject, no subscription | Subscription: Free 100 credits/mo, paid $20 to $100/mo |
PolyMedium pros
- • The subject is detected for you, then matched to a pipeline tuned for it
- • Scan-faithful engines reproduce what your photo shows, which wins on mechanical objects and hard-surface props
- • A $0.25 object draft reconstructs a whole object from a single 3/4 photo
- • Pay only for what you generate: failed jobs refund automatically, exports are free
Trade-offs
- • No rigging or animation step: Meshy sells rigging as a follow-on stage, PolyMedium ends at the mesh
- • Prior-heavy engines like Meshy's can invent flattering detail on organic characters that a scan-faithful engine will not add
- • At high steady volume, a subscription's effective per-model rate can undercut per-model pricing
Verdict
Pick PolyMedium for objects, props, and drawings, where faithfulness to the reference matters and $0.25 iteration is the workflow. Pick Meshy if you want rigging in the same tool or generate enough volume every month to make a subscription pay for itself.
The structural difference behind every row above: most tools on this page sell you one engine. PolyMedium tested 41 engines and routes each upload to whichever wins on that subject — including, at some tiers, engines from the companies it is compared against.
FAQ
Which is cheaper, PolyMedium or Meshy?
For occasional and low-volume use, PolyMedium: an object or a drawing is a flat $0.25 and a character is $0.50 to $3.00, from a prepaid wallet with no subscription. Meshy sells subscriptions: a free tier with 100 credits a month, then Pro at $20/month, Premium at $40/month, and Ultra at $100/month (meshy.ai/pricing, checked 2026-08-30). At Meshy's $20 entry price you would need roughly 80 PolyMedium objects a month before the subscription broke even.
Which is better for mechanical objects and drawings?
PolyMedium. Its TRELLIS-class engines are scan-faithful: they reconstruct the geometry that is actually in your reference instead of substituting a learned prior. On our bench that wins on hard-surface and mechanical subjects, and it is why kids' drawings keep their drawn proportions instead of growing invented features.
Which is better for organic characters?
This one is genuinely closer. Prior-heavy generation, Meshy's approach, is at its strongest on organic characters, where a learned prior fills in plausible anatomy. PolyMedium answers with a dedicated character ladder ($0.50, $1.00 standard, $3.00 figurine-grade hero) benchmarked per subject rather than one general pipeline. If you also need the character rigged and animated in the same tool, Meshy has that step and PolyMedium does not.
