Trellis 2 — Image to 3D with Clean, Predictable Topology
Clean 3D Topology from a Single Image
Trellis 2 is Microsoft's image-to-3D model, built to turn a single picture into a well-structured GLB mesh. Upload an image of an object or character, and TRELLIS reconstructs its shape and texture in one pass. The model focuses on clean topology that imports reliably and is easy to retexture. Choose an output resolution of 512, 1024, or 1536 to balance speed and fidelity. Each result is a standard GLB ready for the web, game engines, and AR. Preview it interactively on this page: orbit, zoom, and inspect the model from every angle before downloading. It's a fast, reliable way to turn a flat image into a practical 3D asset.
TRELLIS treats 3D generation as a structured pipeline rather than a single black box, which helps it produce tidy meshes. For most production work, clean topology matters more than raw triangle count: it allows a rigged model to deform naturally, subdivide without artifacts, and accept new textures without stretching. Trellis 2 prioritizes exactly that, making its assets easier to edit in Blender, Maya, or your engine of choice.
Resolution is the main quality control. The 512 setting is the fastest and least expensive, making it ideal for quick iterations and previews. The 1024 setting offers a balanced default for most assets, while 1536 delivers the highest fidelity when you need crisp surface detail. Texture size scales with the geometry so materials stay sharp at higher settings. Every result is a standard GLB that works directly with three.js, Babylon.js, Unreal, Unity, and any glTF viewer.
The workflow is simple: use one clear image with the subject isolated from the background for the best reconstruction. Choose a resolution, generate the model, and inspect it in the built-in viewer. When you're satisfied, download the GLB. Every generation is also saved in your dashboard gallery for later.
How to Generate a 3D Model with Trellis 2
Upload an Image
Choose a single, clear image with your subject separated from the background. An object or character on a plain backdrop gives the cleanest reconstruction.
Choose Resolution
Pick 512 for fast iteration, 1024 for a balanced result, or 1536 for maximum fidelity. Higher resolutions take a little longer and cost a few more credits.
Generate & Download
Click Generate, then orbit and zoom the model in the interactive viewer. Download the GLB — every generation is also saved to your dashboard gallery.

Why Choose Trellis 2
Clean Topology
TRELLIS prioritizes tidy, edit-friendly meshes that import predictably, deform sensibly when rigged, and accept new textures without stretching.
Resolution Control
Choose 512, 1024, or 1536 to trade speed for fidelity, with texture size scaling alongside the geometry so materials stay sharp at higher settings.
Standard GLB Output
Every result is a standard GLB that drops straight into three.js, Babylon.js, Unreal, Unity, and any glTF viewer — preview interactively before you download.

Frequently Asked Questions About Trellis 2
What does the resolution setting change?
Resolution controls the fidelity of the generated geometry and texture. 512 is the fastest and cheapest option for quick iteration, 1024 is a balanced default for most assets, and 1536 produces the most detailed result. Higher resolutions take a little longer and cost a few more credits.
What file format does Trellis 2 output?
Trellis 2 outputs a standard GLB file — the glTF binary format used across the web, game engines, and AR. It loads directly in three.js, Babylon.js, Unreal, Unity, and any glTF-compatible viewer, including the interactive preview on this page.
Why does clean topology matter?
Clean topology means the mesh is structured in a way that's easy to work with: it deforms sensibly when rigged for animation, subdivides without artifacts, and accepts new textures without stretching. For most real production work this matters more than raw triangle count, and it's a core focus of TRELLIS.
How long does generation take?
Usually one to two minutes depending on the resolution you choose. Generation runs asynchronously — progress is shown on the page and the finished model is saved to your dashboard gallery, so you can navigate away and return.
Can I use the models commercially?
Yes. Models generated with Trellis 2 support commercial use, including games, products, client work, and monetized content. Download your file within 7 days — gallery media is cleaned up after that window.
How is this different from Hunyuan 3D V3.1?
Trellis 2 focuses on clean, edit-friendly topology with explicit resolution and texture-size control, and outputs GLB. Hunyuan 3D V3.1 emphasizes high-fidelity geometry with optional PBR materials and both GLB and OBJ export. Run the same image through both and keep whichever result best fits your workflow.
