What is TRELLIS.2 (trellis-2)?
TRELLIS.2 (also written as trellis-2, trellis 2, or trellis.2) is a modern image-to-3D model that turns a single image into a textured 3D asset. In plain words: you give it a picture, it gives you a 3D model you can rotate, download, and use in your pipeline.
If you’re landing on trellis-2.com, the whole point is simple:
- Upload an image
- Generate a 3D model
- Export as GLB
- Use it in Blender / Unity / Unreal / Three.js
trellis-2 vs trellis 2 vs trellis.2 — do they mean different things?
They’re the same intent keywords people type in different ways:
- trellis-2: hyphen version (common in domains)
- trellis 2: space version (common in search)
- trellis.2: dot version (common in model naming)
On this site, all three spellings refer to the same TRELLIS.2 image-to-3D workflow.
How image-to-3D works on trellis-2.com (high-level)
Think of it like a “3D reconstruction + texture painting” workflow, but automated:
- The model reads your image and guesses the object’s shape in 3D.
- It builds geometry (the mesh) from that guess.
- It generates PBR textures so the surface looks realistic.
- You export a GLB so it works everywhere.
Best input images for TRELLIS.2 (trellis-2)
If you want higher success rate, use images like these:
- A single main object (not a busy background)
- Clear silhouette (strong contrast)
- Good lighting (avoid heavy shadows)
- Ideally alpha-masked / cut-out object (background removed)
Bad inputs usually look like:
- Multiple objects overlapping
- Very cluttered scenes
- Extreme motion blur
- Tiny object in the frame
Key settings you’ll see (and what they actually mean)
Even if the UI shows advanced sliders, the mental model is:
- Resolution (512 / 1024 / 1536): higher = more detail, slower, more GPU.
- Seed: same seed + same image = more repeatable results.
- Decimation target: lowers triangle count (lighter model, less detail).
- Texture size (1024 / 2048 / 4096): higher = sharper textures, larger files.
For most people:
- Start with 512 to evaluate the shape at the lowest credit cost
- Texture 2048
- If you need max detail, go 1536 + 4096
Export workflow: GLB → Blender / Unity / Unreal
Blender
- Import GLB:
File → Import → glTF 2.0 - Check scale, normals, and UVs
- Optional: decimate / retopo / bake textures
Unity / Unreal
- GLB is a great interchange format.
- If you need FBX, import GLB into Blender first, then export FBX.
FAQ (quick answers)
Is TRELLIS.2 (trellis-2) open source?
The upstream TRELLIS.2 project is published in the Microsoft GitHub repository. This site (trellis-2.com) is an independent service, not the model author and not a Microsoft website.
Why does the “back side” sometimes look wrong?
Because a single image can’t show the hidden side. The model must predict / hallucinate the unseen area. For best results, use images with strong cues (symmetry, clear materials).
Can I use the 3D model for games?
Yes, but expect to do the same “game-ready” steps you’d do for any generated asset:
- reduce polycount
- check UVs
- fix materials
- create LODs if needed
