Independent review. I ran both tools on my own accounts, free and paid, with no vendor-provided access or early access of any kind.
I needed one character bust for a WebXR scene. Visored helmet, ear cups, armoured shoulders. Nothing exotic.
I had the reference image. What I didn't have was a modeller, or three weeks.
So I asked around. Every single time, the same two names came back: Meshy and SupaVoxel. Fine. I took one image, ran it through both, downloaded both files, and pulled them apart to see what I'd actually been handed.
Here's what I found.
My verdict in 60 seconds — Meshy 61/100, SupaVoxel 89/100
Those are my scores for this one job. Subjective, and based on one image and one run per tool — not a lab study.
- Triangles — Meshy 2,490,490 vs SupaVoxel 1,487,122 · Meshy 5/10 · SupaVoxel 9/10 — Meshy spends a million extra triangles on a bust that stops at the collarbone; SupaVoxel draws the same silhouette with a million fewer for your frame budget to chew through
- Vertices — Meshy 1,331,208 vs SupaVoxel 944,806 · Meshy 5/10 · SupaVoxel 9/10 — Meshy makes your engine upload 386,402 extra points on every single load; SupaVoxel gets the scene on screen with fewer
- Geometry buffer memory — Meshy 72.48 MB vs SupaVoxel 48.08 MB · Meshy 5/10 · SupaVoxel 9/10 — Meshy eats about 24 MB more before a texture is even decoded; SupaVoxel leaves you that headroom for a second character
- Download size — Meshy 79,664,932 bytes vs SupaVoxel 12,385,676 bytes · Meshy 4/10 · SupaVoxel 9/10 — Meshy's export is five times the payload for the same bust; SupaVoxel's is small enough to put on a page today
- Export options — Meshy one GLB vs SupaVoxel compressed GLB and original-size GLB · Meshy 6/10 · SupaVoxel 9/10 — Meshy gives you one file and you live with it; SupaVoxel hands you both deliverables from a single run, so the web build and the fussy importer each get the right one
- Export format — GLB on both sides · Meshy 8/10 · SupaVoxel 8/10 — a tie, and an honest one: both tools export the same single-file format, so nothing separates them here
- Embedded texture maps — 3 vs 3 · Meshy 7/10 · SupaVoxel 7/10 — another tie; neither tool skimps on the number of maps, whatever else they differ on
- Failure and retry counts — not captured on either side · Meshy 6/10 · SupaVoxel 6/10 — a tie by default: this run recorded neither, so I have nothing to separate them with and won't pretend otherwise
Three things I kept coming back to.
Meshy spent 2,490,490 triangles on a bust that stops at the collarbone. The other file did the same silhouette in 1,487,122.
Meshy's download is 79,664,932 bytes. That's the file your build has to carry, cache and ship. Every time.
And Meshy's 1,331,208 vertices push a plain geometry buffer to around 72.48 MB before a single texture is decoded.
For this bust, I kept the SupaVoxel file and carried on from there. If you want to see the tool I ended up using, it's at supavoxel.com.
Meshy's bust, rendered offline in my own viewer at a fixed camera and fixed lighting. Not a screenshot of Meshy's preview.
Same camera numbers, same lights, the other file. The two models sit at slightly different angles because each file carries its own built-in orientation — so don't read this as an overlay.
So which file actually makes it into your scene?
Quick vocabulary, because it matters in a second.
A GLB is the single-file version of glTF. Model, materials and textures in one bundle. Both tools handed me one.
A triangle is one flat shard of the surface. Stack up a couple of million and you get a face. Your headset has to draw all of them, every frame, sixty or ninety times a second.
So the triangle count isn't trivia. It's a bill, and Meshy hands you the bigger one.
And Meshy's bill is bigger.
Why Meshy hands you 1,003,368 extra triangles
Meshy: 2,490,490 triangles. The SupaVoxel file: 1,487,122. That's 1,003,368 more, for the same helmet, the same visor, the same two shoulders.
Sounds like more detail, right?
Not automatically. Nothing in what I measured says the extra triangles went anywhere useful — and later, in the close-ups, they clearly didn't save the ear cup.
What they definitely do is show up in your scene. A million extra triangles is a million more things to sort, cull and draw. If you're putting four of these busts in a gallery room, Meshy just added four million triangles to your frame budget.
You pay for that in frames, not in file size.
Meshy with the texture stripped off: 2,490,490 triangles doing the work.
Same pass, same camera, 1,487,122 triangles. Same bust, a million fewer shards.
Meshy uploads 386,402 more points, every single load
Vertices are the corners, and Meshy ships more of them. They're what your engine actually pushes to the GPU.
Meshy: 1,331,208. SupaVoxel: 944,806.
That Meshy gap — 386,402 vertices — is the part nobody warns you about. It's not a one-time cost. It's every load, every scene switch, every time a user walks into that room.
Fewer points in means a shorter wait before anything appears.
Here's what Meshy's geometry costs you in memory
Let me put a number on it.
Take a plain vertex layout — position, normal, texture coordinate — and count the index data for the triangles. Meshy's geometry works out to about 72.48 MB. The other file: 48.08 MB.
Same bust. About 24 MB apart, and Meshy is on the expensive side.
Meshy's twenty-four extra megabytes don't sound like much on a desktop. On a standalone headset, where you're juggling a scene, textures and your own app in a fixed budget, 24 MB is a feature you now can't ship.
And that's geometry only. No textures in that number at all.
Look at the wireframe, not just Meshy's triangle count
Totals lie, and Meshy has the bigger total. Distribution doesn't.
Here's where each tool actually spent its triangles.
Meshy's wireframe close-up. Watch where the edges bunch up and where they go sparse.
The other file at the same camera. Fewer edges overall — but look at where they land.
This is the check worth running on any Meshy model — or any model you didn't build yourself. A high triangle count that's evenly smeared across flat armour plates helps nobody. You want density where the shape changes.
What the front view tells you about Meshy's visor
Same camera numbers on both. The models sit at different built-in angles, so this isn't a pixel-for-pixel overlay — but you can still read the surfaces.
Meshy from the front. The visor reads as one broad slab with a single line of trim along the top.
Same camera, other file. The visor has an actual bevel, and the trim follows the rim instead of cutting across it.
The moment a triangle count actually bites you
Let me make this concrete, because "2,490,490 triangles" is an abstraction until it isn't.
Picture a small gallery room. Four of these Meshy busts on plinths, one per corner. That's the scene I was building.
With Meshy's file that's four copies of 2,490,490 triangles before you add a floor, a wall or a light. With the other file it's four copies of 1,487,122. Same room, and Meshy's version is carrying a million extra triangles per corner.
Now the user turns their head inside Meshy's room. Every one of those triangles has to be considered, culled and drawn, twice — once per eye — sixty or ninety times a second.
That's when the number stops being a spec and starts being a dropped frame.
And you find out at the worst possible moment: not while you're modelling, not while you're exporting, but when someone puts the headset on and the room stutters as they turn.
And then there's the file you actually have to carry
Meshy's geometry is only half the bill. The other half is what you move across a network.
Meshy's export is 79,664,932 bytes. The other file is 12,385,676 bytes. Both are GLB — same format, same export click, five times the weight.
Run that through a normal connection and you get the wait your user actually experiences. At a steady 12 Mbps, Meshy's file needs about 53.1 seconds of pure transfer; the other one needs 8.3. On a 100 Mbps line it's 6.37 seconds against 0.99.
Those are arithmetic, not a network test — file bytes × 8 ÷ bandwidth, at an assumed steady downlink, ignoring latency, caching and decode. But the shape is right, and 53 seconds of spinner is 53 seconds of someone deciding to leave.
Under a second feels like the page. Six seconds needs a loading screen you have to build.
Scale Meshy up and it gets worse. A hundred assets at Meshy's size is 7.97 GB on disk; the other file makes the same library 1.24 GB. That's the same file counted a hundred times — a capacity exercise, not a hundred real runs, and it says nothing about how often either tool succeeds.
Same arithmetic on the ledger, for completeness: a hundred runs would be 3,500 Meshy credits against 300 on the other side. Two different plans, two different units — not a price ratio, and I'm not converting either into money.
One more Meshy data point that surprised me. To get both models into a browser viewer I ran each through the same conversion. Meshy's browser copy came out at 13.64 MB; the other one at 7.58 MB. Meshy's converted file is still heavier than the other tool's original export — and the conversion shifted one model's triangle count by 2, which is exactly why every number in this article comes from the untouched originals.
The settings I gave Meshy, and the ones I gave the other tool
One image. One run each. No text prompt on either submission — just the picture.
Both runs happened the same morning: the Meshy job went in at 02:30:57 UTC, the other at 03:07:41. Same four stages on both sides — upload the image, set the options, look at the result, hit export.
The reference going into Meshy. Account details blacked out.
The same image going into the other tool.
Meshy's settings for this run: Image to 3D, Meshy 7.1, High Detail, Ultra 2K, texture on.
The other panel: 5 steps, guidance 5.5, background removal on, octree resolution 256. Different products, different knobs — I didn't try to match compute.
Two exports from one run, which is the part I didn't expect
Here's the thing nobody mentioned when they recommended these tools to me.
The SupaVoxel export menu gives you both: a compressed GLB and an original-size one. Same run, same model, two deliverables.
That matters because the web build and the picky importer want opposite things. The web build wants the 12,385,676-byte file that arrives in 8.3 seconds on a slow line. A tool that won't install a meshopt decoder wants the original-size version, which doesn't ask for one.
With Meshy you get one GLB and you make it fit everywhere, whatever "everywhere" turns out to mean.
One generation, two deliverables, no re-run and no hunting for a converter. That's the whole pitch, and it's the reason the extension question stopped being a problem for me about ten minutes after I noticed the menu.
Where Meshy actually wins
I'm not going to bury this one, because if it applies to you it decides everything.
Open a GLB and it can declare extensions it requires — bits of the format your importer has to understand or it simply won't open the file. meshopt is one of those: a compression scheme that makes the file much smaller, as long as whatever opens it can decode it.
Meshy's file requires nothing. Zero extensions. It drops into a plain glTF importer with nothing installed.
The compressed SupaVoxel file requires two: meshopt compression and mesh quantization. Switch to the original-size export sitting in the same menu and that decoder requirement goes away. I didn't test the import in any specific tool — I'm reading each file's own declaration, not a result.
With Meshy's file there's nothing declared at all, so there's nothing to install and you can attempt a straight import. Whether it then succeeds is something I can't tell you, because I never loaded either file into a specific tool. What I read was the requirements list, and Meshy's is empty.
So what's that worth? Here's the exchange rate.
Meshy's no-install convenience costs you 79,664,932 bytes instead of 12,385,676. A million extra triangles. About 24 MB more geometry memory. That is a lot to pay for one property of the file — and on the SupaVoxel side you don't have to choose, because the original-size export covers the same case out of the same run. But if all you have is Meshy's single file and a client who won't install anything, Meshy is the delivery that works.
Meshy takes a second point too: its three texture maps are 2048×2048 against the other file's 4096×4096. Four times fewer pixels per map means a much lighter texture budget — roughly 50.33 MB against 201.33 MB if you force both to decode raw. On a memory-bound headset, that's Meshy's argument, and it's a good one. You pay for it in the close-ups.
Meshy from above.
Same camera, other file.
What I couldn't measure — and won't pretend I did
I don't have Meshy's generation time. Meshy didn't record one I could read. Neither were failure counts or retry counts, on either side.
I also never put the Meshy bust, or the other one, on a headset. No frame rate, no draw calls, no comfort test.
What I do have on the other side is a recorded generation window of 268.043 seconds — about four and a half minutes from start to finish, download not included. That's one number from one run, and with nothing to compare it to it tells you what to expect from that tool on that day, and nothing about Meshy.
So nobody here gets to claim a speed win, and nobody gets to claim "production ready." What I can tell you is exactly what landed on my disk: two GLB files, one 79,664,932 bytes and one 12,385,676, each with its own checksum, each parsed offline rather than described from a dashboard.
On credits: the run recorded 35 on Meshy's side and 3 on the other. Two different plans, two different units. I'm not turning that into a dollar comparison, and you shouldn't either.
So which one do you pick for a VR bust?
- Shipping to the web or a headset? Take the 12,385,676-byte file. Not Meshy's 79.7 MB.
- Handing the file to a tool that won't install anything? Meshy's file has no requirements at all — and SupaVoxel's original-size export doesn't either, which is exactly why that menu has two entries.
- Tight on frame budget? 1,487,122 triangles beats Meshy's 2,490,490 before you optimise a thing.
- Tight on texture memory instead? Meshy's 2K maps are the lighter load.
- Chasing the lowest price? Can't answer that from this run. Different plans, different units.
Final verdict: Meshy scores 61/100 for this job
Meshy delivered a usable bust. Meshy also handed me a million extra triangles, 386,402 extra vertices, 79.7 MB to carry, and about 24 MB of extra geometry memory — for a bust that ends at the shoulders.
Meshy's clean win is the file that opens anywhere. That's worth real money to some of you. It wasn't worth it to me.
61/100 is my call on this one job, one image, one run each. Not an average, not a ranking of Meshy across every subject.
Try it with your own image
Don't take my word for a single run. Take the picture you actually need turned into a model, push it through Meshy and through the other one, and open both files.
The one I kept was the 1,487,122-triangle, 12,385,676-byte export — you can run your own reference through the same tool at supavoxel.com. Take the compressed GLB for anything that downloads and the original-size one if your importer is fussy, and check the texture load if your target is memory-bound.
Then judge from your file, not mine.
How I tested this
One reference image, generated with GPT Image 2, uploaded to Meshy and to SupaVoxel with no text prompt. One run each. Both GLBs downloaded, hashed, and parsed offline — every triangle, vertex, texture and extension figure above is read from the file itself, not from a product page.
All renders are mine: one offline viewer, identical lighting and resolution, identical camera numbers on both sides. Each GLB carries its own built-in orientation, so matching camera numbers don't guarantee matching poses. Treat the pairs as two models under one camera.
The geometry memory figures — 72.48 MB and 48.08 MB — are arithmetic, not a profiler reading: 32 bytes per vertex (position, normal, UV) plus 4 bytes per index, three indices per triangle. The texture figures, 50.33 MB and 201.33 MB, are also arithmetic: three maps decoded as raw RGBA, no mipmaps, no runtime compression. Real engines rarely do that. Both are sizing exercises, not measurements.
UI screenshots were redacted before publication. Credits, failure counts and retry counts come from the run record where they exist — and where they don't, I've said so.
