AI Retopology

AI Retopology: Clean Quad Meshes in About a Minute

AI retopology rebuilds a messy, dense mesh into clean quad or triangle topology automatically, at the polycount you choose. Meshy's Remesh runs it free in your browser — 0 credits, nothing to install.

How to Retopologize a 3D Model Online

Retopology rebuilds a 3D model's polygon structure into clean, evenly flowing topology while keeping the original shape intact. Meshy's Remesh runs the whole process automatically in your browser — the panel estimates about a minute per model, at 0 credits.

Upload or Generate Your 3D Model
Upload your own model (FBX, OBJ, STL, glTF, or GLB, up to 100MB) or create one with Text to 3D or Image to 3D — Remesh sits in the toolbar right next to Texture. Pipelines can run the same job through the Remesh API.
Pick Topology & Polycount
Choose quad-dominant or triangle output, then set the target polycount: Fixed or Adaptive mode, presets from 3K to 100K plus a custom field. The Remesh API accepts anywhere from 100 to 300,000 polygons.
Export in 8 Formats
Download the retopologized mesh as GLB, FBX, OBJ, USDZ, STL, BLEND, 3MF, or DXF — ready for game engines, DCC tools, CAD, and 3D printing. Your textures carry over to the new topology; run Retexture only if you want a fresh look.

Why Choose Meshy's Auto Retopology Tool

Quad or Triangle Output

One switch in the Remesh panel: a quad-dominant mesh for animation, sculpting, and clean edge flow, or a decimated triangle mesh for game engines and real-time work.

Full Polycount Control

Fixed and Adaptive modes with presets at 3K, 10K, 30K, and 100K faces plus a custom field. Through the Remesh API the target ranges from 100 up to 300,000 polygons.

Shape Stays Intact

Remesh regenerates the wireframe, not the silhouette. Face count and arrangement are optimized while the original form of your model is preserved.

8 Export Formats

Download the retopologized mesh as GLB, FBX, OBJ, USDZ, STL, BLEND, 3MF, or DXF — one pass covers game engines, DCC tools, AR, CAD, and 3D printing pipelines.

Free in the Browser

Remesh runs at 0 credits in the Meshy workspace, with an estimate of about a minute per model. No plugin, no desktop retopology software to install, no queue on your GPU.

Textures Carry Over

Remesh a textured model and it comes out textured — the maps follow the new topology, quad or triangle, so you never ship a gray model. Want a different look? Retexture is one click away.

One Mesh, Your Choice of Topology

The same 3D model remeshed two ways: quad-dominant for animation and editing, lean triangles for real-time. The shape stays identical, and the texture carries over.

Dense AI Mesh (Input)

What image-to-3D and text-to-3D hand back: a dense, uneven surface that renders fine but fights every rig, edit and engine budget.

Quad Output

Quad-dominant edge flow that deforms predictably — the topology sculpting, rigging and subdivision expect. Target anything from 3K to 300K faces.

Triangle Output

A decimated triangle mesh sized to a frame budget, ready for Unity, Unreal, Godot or the web. Same silhouette, a fraction of the faces.

Textures Intact

The maps follow the new wireframe, so a textured model comes back textured — no rebake, no gray model, whichever topology you picked.

How Does AI Retopology Fit Your Workflow?

Remesh earns its place wherever a dense mesh — AI-generated, sculpted, or scanned — has to animate, ship, print, or run in real time as GLB or USDZ for VR, AR, and the web. Drop it in as one step, and cleanup stops being a stage of its own.

Character Animation

Speeds up the sculpt-to-rig handoff: Remesh turns dense sculpts and AI-generated characters into rig-ready topology in about a minute, so the day goes to animating — not mesh cleanup.

Game Development

Accelerates asset iteration: remesh every model to its poly budget in one click, textures included, and keep shipping builds instead of hand-optimizing meshes.

3D Printing

Cuts prep before printing: clean, even topology plus the built-in printability check take a design straight from the viewer to a slicer-ready STL or 3MF.

Switching to Meshy was a great move for me due to its superior remeshing capabilities. These features combine to make my experience with Meshy exceptionally satisfying.

Nils S.

Game Development

Meshy is easy. Models and textures are impressively detailed and accurate. Great for 3D printing. Great for prototyping. Better high poly mesh generator.

Joseph L.

Software Engineer

I like the quality of the mesh in Meshy and the animation feature is very good, especially when you have quality input. I'm glad that I can see the updates improving — someday it's going to be pretty fantastic.

Frequently Asked Questions

Retopology rebuilds the wireframe from scratch: the AI generates new, evenly flowing (quad-dominant) topology at your target polycount. Decimation only removes triangles from the mesh you already have, so the leftover wireframe stays irregular. Choose retopology when the model is headed for animation, sculpting, or clean UVs. If all you need is a lower face count on the existing mesh, use the free Polygon Reducer instead.

Upload .fbx, .obj, .stl, .gltf, or .glb files (up to 100MB) straight into the workspace, or remesh any model you generated in Meshy — open it and click Remesh in the toolbar next to Texture. Download the result in 8 formats: GLB, FBX, OBJ, USDZ, STL, BLEND, 3MF, or DXF. The Remesh API accepts the same input formats for automated pipelines.

Yes — they carry over. Remesh a textured model and the result keeps its textures on the new topology, whether you choose quad or triangle output. Want a different look instead? Run Retexture on the remeshed model and Meshy repaints it in one pass.

AI quad remeshing shines on organic shapes — characters, creatures, and sculpts, where even edge flow matters most. Hard-surface models with crisp machined edges can soften at aggressive polycounts, so give them a higher target or triangle output and check the wireframe before you export. Our AI retopology guide walks through both cases.

In the browser, Remesh runs at 0 credits — the panel shows the cost before you start, and every Meshy account works without a credit card. If you've been shopping for free retopology software, this is it: nothing to download. Remesh tasks through the API bill credits per task; see pricing for plan details.

Quad-dominant output is the default for anything that deforms or gets edited: animation, rigging, sculpting, and DCC round-trips. Triangle output produces a lean mesh that matches what game engines render natively, so it's the right choice for real-time scenes where the wireframe will never be hand-edited again.

Yes — pick the Smart Topology model type when you generate with Text to 3D or Image to 3D, and choose quad or triangle output from the start. Character artists can begin from the AI Character Generator, then Remesh only when a different polycount budget is needed, and finish with AI auto rigging — clean topology is what makes the rig deform well.
