TRELLIS 2 and Meshy can both turn a reference image into a textured 3D asset, but they solve different parts of the workflow. TRELLIS 2 is the better starting point when you specifically want Microsoft's open model, high-resolution generation, and explicit sampling controls. Meshy is the better fit when topology choices, remeshing, rigging, animation, and multiple delivery formats matter more. Output quality still needs a same-input test; a feature table cannot choose a universal winner.
TRELLIS 2 vs Meshy at a glance
| Decision area | TRELLIS 2 | Meshy v6 |
|---|---|---|
| Core product shape | Open image-to-3D model plus hosted tools | Hosted creator platform and API |
| Main controls here | 512³, 1024³, 1536³; texture size; remesh; decimation; seed and sampling | Triangle or quad topology; target polycount; remesh; texture; PBR; pose; rigging and animation |
| Material workflow | Base color, roughness, metallic, and opacity in a GLB-oriented workflow | PBR maps with configurable texture and topology workflows |
| Delivery | GLB preview and download on trellis2.com | API documents GLB and additional asset formats |
| Local use | Official code and model are available; supported setup is Linux with a high-memory NVIDIA GPU | Primarily a hosted Studio/API workflow |
| Best for | TRELLIS-specific research, resolution testing, open-model workflows | Production convenience and downstream asset preparation |

Where TRELLIS 2 is different
Microsoft describes TRELLIS.2 as a 4B-parameter model built around O-Voxel, a representation designed for complex topology and PBR attributes. Its reference workflow supports resolutions from 512³ through 1536³ and exports GLB assets with base color, roughness, metallic, and opacity information.
On trellis2.com, the premium generator exposes the settings that matter when you want a repeatable TRELLIS test:
- output resolution
- texture size
- optional remeshing and decimation target
- seed, sparse-structure sampling, shape sampling, and guidance controls
- browser preview and original GLB download
The model is open source, but local use is not lightweight. Microsoft's documented setup targets Linux and an NVIDIA GPU with at least 24 GB of memory. The hosted TRELLIS 2 generator removes that local hardware requirement.
Where Meshy is different
Meshy v6 exposes more post-generation choices in one hosted workflow. Its current image-to-3D API documents:
- triangle or quad topology
- a target polygon count and optional remeshing
- PBR material generation
- pose controls for compatible subjects
- optional rigging and animation
- multiple export formats and downloadable model assets
That makes Meshy attractive when a generated object must immediately enter a character, ecommerce, or game-asset pipeline. These controls do not automatically prove better geometry; they reduce the number of separate tools needed after generation.
You can test the current integration on the Meshy model page or open the Meshy generator. Pricing and credit costs can change, so use the live interfaces rather than a copied number in this article.
Which one should you use?
Choose TRELLIS 2 when:
- the Microsoft TRELLIS.2 model is itself part of your requirement
- you need to test 512³, 1024³, or 1536³ generation
- you want control over sampling, guidance, remeshing, and texture size
- an open model and a traceable upstream implementation matter
- GLB is your primary handoff format
Choose Meshy when:
- triangle versus quad topology is a first-order decision
- you need a target polygon count in the generation workflow
- rigging, animation, or pose controls reduce downstream work
- you need a hosted creator workflow with several export choices
- your team values convenience over running an open model locally
If neither list settles the decision, use the multi-model image-to-3D tool and compare exported files from the same source image.
How to run a fair TRELLIS 2 vs Meshy test
Use at least five source images: one hard-surface object, one organic object, one thin or open structure, one reflective product, and one partially occluded object.
For every run:
- keep the original image unchanged
- record model version, selected settings, credits, queue time, runtime, and retries
- download the original output rather than judging only the web preview
- inspect silhouette, hidden surfaces, topology, UVs, material maps, polygon count, non-manifold edges, and file size
- import both assets into the same Blender scene and lighting setu p
- report manual cleanup time separately
Without this dataset, claims such as “Meshy is faster” or “TRELLIS 2 has better geometry” are input-dependent opinions.
Frequently asked questions
Is TRELLIS 2 better than Meshy?
There is no universal winner. TRELLIS 2 offers a specific open model, high-resolution modes, and detailed generation controls. Meshy offers a broader hosted production workflow. Test both with assets representative of your pipeline.
Can TRELLIS 2 run locally?
Yes. Microsoft publishes the code and model, but the documented environment is Linux with a high-memory NVIDIA GPU. Hosted generation is simpler when that hardware is unavailable.
Does Meshy support quad models?
Meshy's current image-to-3D API documents triangle and quad topology options. Check the live documentation for model-version and plan constraints before standardizing a production pipeline.
Can both tools export GLB?
Yes. TRELLIS.2's reference implementation and trellis2.com use GLB, while Meshy's current API also returns GLB model assets. Meshy documents additional delivery formats.
