TRELLIS 2 (TRELLIS.2)A practical workbench for image‑to‑3D assets.

Try the official demo, then preview the generated GLB locally to sanity‑check geometry and materials before you import into Blender / Unity / Unreal. No accounts. No paywalls.

What is TRELLIS.2?

TRELLIS.2 is a large 3D generative model designed for image‑to‑3D: given a single image, it produces a textured mesh with PBR material attributes (including opacity). It’s built around a sparse voxel representation called O‑Voxel, aiming to keep topology faithful even for open surfaces and non‑manifold geometry.

Why it’s interesting
  • Field‑free topology handling (not limited by iso‑surface fields)
  • Rich appearance: base color, roughness, metallic, opacity
  • Compact structured latents via sparse 3D VAE (16× spatial compression)

A workflow that matches real needs

1) Generate (online)
  1. Upload a clean, single‑subject image (simple background helps)
  2. Generate the model (wait for compute)
  3. Download/export GLB if available
  4. Move to validation before importing
Jump to embedded demo →
2) Validate + export (local)

Before you import into Blender/Unity/Unreal: rotate, zoom, check silhouette, inspect materials, then export GLB. Use the built‑in previewer to catch issues early.

Preview your GLB before you import

The fastest way to avoid “why does this look wrong in Blender?” is to validate the exported file immediately. This preview runs locally in your browser—your file isn’t uploaded by trellis2.com.

GLB preview (local)
No uploadWorks best with .glb
If the demo provides a GLB download, grab it and drag it here to check geometry and materials before you import it into Blender / Unity / Unreal.
Tip: If you can’t get a GLB from the hosted demo, try running locally (GPU required) from the official repo.

Use cases

Game prototyping
Generate placeholder assets fast, then iterate with artists.
Product 3D mockups
Turn a product photo into a quick 3D preview for web or AR.
AR/VR content
Create PBR assets for scenes, props, and environment dressing.
Research & benchmarking
Compare topology, material quality, and speed across pipelines.

Reality check

Not guaranteed watertight
Small holes and artifacts can happen. For 3D printing or strict CAD needs, expect post‑processing.
GPU‑heavy locally
The official repo notes Linux + NVIDIA GPU (≥24GB VRAM). Online demos can queue or rate‑limit.
Input image matters
Clear subject, good lighting, and visible material cues dramatically improve results.

FAQ

Is TRELLIS 2 the same as TRELLIS.2?
Yes. People write it as “TRELLIS 2”, “TRELLIS.2”, or “Trellis2”. The official project name is TRELLIS.2.
What does TRELLIS.2 do?
It turns a single image into a 3D asset: a mesh plus PBR materials (e.g., base color, roughness, metallic, opacity).
Can I try it for free?
Yes—this site embeds the official Hugging Face Space. You can upload an image and generate a model in the browser.
Do you upload my 3D files when I preview a GLB here?
No. The GLB preview runs locally in your browser using a file you choose. The file stays on your device unless you upload it somewhere else.
What file format do I get?
The official pipeline supports exporting GLB. The demo may offer a GLB download depending on its current configuration.
What hardware do I need to run it locally?
The official repo notes Linux + an NVIDIA GPU with at least 24GB VRAM. It has been verified on A100/H100 class GPUs.
Why do I see small holes or mesh artifacts?
Even with strong topology handling, raw meshes can have small discontinuities. For strict watertight requirements (e.g., 3D printing), you’ll likely need post-processing (hole filling / remeshing).
Does it support transparent materials?
TRELLIS.2 models PBR materials including opacity, so transparency / translucency is part of the representation.
Is this model aligned (RLHF) for aesthetics?
The published model card describes it as a pre-trained foundation model without preference alignment; outputs can vary in style.
Is it open source?
Yes—the code and model are released under MIT per the official repository/model card (check linked sources for details and dependencies).
How do I get better results from a single image?
Use a clear subject, avoid busy backgrounds, keep the subject large in frame, and prefer images with visible material cues (gloss, metal, transparency) when relevant.
