Remesh / Retopology

Updated May 2026

The Remesh tool rebuilds your model’s mesh topology from scratch. It reduces polygon count, converts between file formats, and bakes textures onto the new geometry. The result is cleaner, lighter geometry ready for games, animation, 3D printing, or web use.

You can access it two ways:

• Standalone tool — Open the Quad Remesh Tool for any uploaded model
• Dashboard Model Actions on any model you have already generated or imported

Providers

There are four remesh providers, each suited to different needs and budgets.

Provider Details

Base (Free) Good for quick format conversions and basic polygon reduction. No credit cost. Supports face count targets and triangulated output. A solid starting point if you just need a lighter version of your model.

Prism The go-to choice for game and animation workflows. Produces clean quad topology (3 credits) or triangulated meshes (1 credit). Offers face count control from 1,000 to 200,000 faces, texture baking, and pre-processing options like vertex cleanup and structure repair.

Pro (Meshy) Handles high-polycount models and outputs to multiple formats. 15 credits per use. Good for production assets that need to keep fine detail while still getting proper topology.

Hunyuan Uses AI to optimize topology placement. The algorithm decides where edges should go based on the model’s shape, placing more detail where it matters and fewer polygons on flat areas. 10-15 credits depending on complexity.

Key Settings

• Face count controls target polygon density. Lower values (1,000-5,000) for mobile/web, higher values (10,000-200,000) for film or print.
• Topology type lets you choose between triangles (better for game engines) or quads (better for animation and subdivision).
• Texture baking captures the original surface appearance and projects it onto the new mesh. Choose resolution from 512 to 4,000 pixels in PNG or JPEG.
• Pre-processing options include vertex cleanup, structure repair, and initial decimation to handle messy source geometry before remeshing.

Export Formats

Remeshed models can be downloaded in any of these formats:

• GLB for web viewers and game engines
• FBX for animation pipelines (Unity, Unreal, Maya)
• OBJ for universal compatibility
• STL for 3D printing (geometry only)
• USDZ for Apple AR
• 3MF for color 3D printing
• BLEND for Blender workflows

Before and After

Here is a model before and after remeshing with the Hunyuan provider, viewed in Blender:

Before: the original mesh with uneven topology and high poly count.

After: clean, optimized topology from the Hunyuan remesh. Notice the even polygon distribution.

Tips

• Start with the Base provider if you just need a format change and do not care about topology quality.
• Use Prism quad for characters you plan to animate. Quad meshes deform much better than triangles.
• Enable texture baking whenever the remesh significantly changes the geometry. Otherwise your textures will not line up with the new mesh.
• For very high-poly source models (100k+ faces), turn on initial decimation in pre-processing. This gives the remeshing algorithm a cleaner starting point.
• If your target is 3D printing, use STL or 3MF format and prioritize structure repair in pre-processing.

What’s Next

After remeshing, you might want to add textures, rig your model for animation, or segment it into parts.

Frequently Asked Questions

How much can I reduce the poly count of a 3D model?

In 3D AI Studio, you can target anywhere from 1,000 to 200,000 faces using the Prism provider. For mobile games, aim for 1,000 to 5,000 faces. For PC games, 5,000 to 30,000 is typical. The Base provider (free) also does basic decimation if you just need a quick reduction without topology cleanup.

What is the difference between quad remesh and triangle remesh?

Quad remesh produces four-sided polygons that deform cleanly during animation and work well with subdivision surfaces. Triangle remesh produces three-sided polygons that game engines prefer for real-time rendering. In 3D AI Studio, the Prism provider offers both options, with quad costing 3 credits and triangle costing 1 credit.

Can I convert 3D file formats without changing the mesh?

Yes. The Base (free) provider in 3D AI Studio handles format conversion between GLB, FBX, OBJ, STL, USDZ, 3MF, and BLEND without spending any credits. It does basic re-export without expensive topology rebuilding, making it useful when you just need a format change.

Does remeshing preserve my model’s textures?

Only if you enable texture baking. When 3D AI Studio rebuilds the mesh topology, the original UV layout changes, so textures will not line up automatically. Enable texture baking in the settings to project the original surface appearance onto the new geometry at resolutions from 512 to 4,000 pixels.

How do I optimize a 3D model for use in a game engine?

Upload your model to 3D AI Studio and use the Prism provider with triangle topology selected. Set your face count target based on platform (1,000 to 5,000 for mobile, 5,000 to 30,000 for PC). Enable texture baking to preserve appearance, then export as GLB for web or FBX for Unity and Unreal Engine.

What is AI retopology and when should I use it?

AI retopology uses machine learning to decide where to place edges based on your model’s shape, putting more detail on curved or complex areas and fewer polygons on flat surfaces. In 3D AI Studio, the Hunyuan provider offers this for 10 to 15 credits. Use it when you need smarter polygon distribution than simple uniform decimation provides.
