Overview
TRELLIS.2 is an independent image-to-3D generator hosted at trellis-2.com: a user uploads one photo and receives a textured 3D model. The site describes itself as an independent third-party platform providing a user-friendly interface for TRELLIS.2 image-to-3D generation, and states that it is not Microsoft and is not affiliated with Microsoft. The underlying model is described as a 4-billion-parameter flow-matching transformer that produces O-Voxel geometry, PBR materials, and a GLB starting asset that can be inspected, cleaned, and adapted.
Generation runs through a managed provider queue, and the site notes that completion time varies with resolution, image complexity, and provider load. Outputs are exported directly to GLB format with embedded PBR textures, including base color, metallic, roughness, and alpha channels, at output levels of 512³, 1024³, and 1536³. According to the pricing page, a 512³ generation uses 150 credits, 1024³ uses 300 credits, and 1536³ uses 500 credits, and GLB export and PBR textures are included.
Accounts with no prior 3D task can receive up to 150 trial credits once, valid for 7 days; later tasks and higher resolutions use purchased credits, and failed tasks automatically return reserved credits. The site recommends clear subject images with alpha-masked foregrounds and presents the generated GLB as a starting asset to review, clean, and optimize before use in game engines, VR/AR, or 3D printing.

Use Cases
- Teams use TRELLIS.2 to turn a clear product image into a GLB draft for internal reviews, layout experiments, or a prototype 3D viewer.
- Game and real-time teams use TRELLIS.2 to produce base meshes for props, environment studies, and art-direction experiments from concept art and reference photos.
- VFX and previsualization teams use TRELLIS.2 drafts for blocking, camera tests, rough props, and early silhouette decisions.
- 3D printing users use TRELLIS.2 to create starting meshes for decorative objects, figurines, and visual prototypes before slicing.
- XR, web, and spatial prototyping teams use generated GLB drafts to populate mockups, spatial-layout tests, educational demos, or early web scenes.
- Architecture and interior concept teams use TRELLIS.2 for early visualization of furniture references, decorative objects, and isolated fixtures.

FAQ
Is trellis-2.com the official Microsoft TRELLIS 2 website?
No. The site states it is an independent third-party image-to-3D service, not Microsoft, not affiliated with Microsoft, and not the official TRELLIS.2 project site; Microsoft publishes the open-source model on GitHub while this site provides its own hosted generator, billing, and support.
What is TRELLIS.2 (trellis-2)?
TRELLIS.2 is described as an open-source 4B-parameter AI model published by Microsoft Research that converts a single image into a 3D starting asset, using an O-Voxel representation and flow-matching transformers to produce GLB files with PBR textures at up to 1536³ resolution. trellis-2.com is an independent hosted workflow around that model.
How does trellis 2 work?
The site explains that images are encoded through a vision encoder and 3D content is generated with a flow-matching transformer, using a Sparse Compression VAE with 16× spatial downsampling to create compact latent representations, while the O-Voxel structure encodes geometry and PBR appearance simultaneously.
What can I create with TRELLIS.2?
Users can create 3D starting assets from product photos, artwork, characters, objects, and more, reviewing topology, scale, materials, and printability before using a generated GLB in games, VR/AR, product visualization, or 3D-printing workflows.
What resolution does trellis-2 output?
TRELLIS.2 supports 512³, 1024³, and 1536³ output levels. The hosted service uses a managed provider queue, so completion time varies with resolution, image complexity, and provider load.
What file format does TRELLIS.2 export?
Models are exported directly in GLB (Binary glTF) format with embedded PBR textures. For PLY, the site says to download the GLB and use the separate browser converter, since PLY is not a direct generator output.
Does trellis.2 support transparency?
Yes. Transparency is supported through the alpha channel in PBR materials, and the system can generate translucent and transparent objects such as glass, windows, and see-through materials; the O-Voxel structure naturally handles alpha transparency.
Is TRELLIS.2 free to use?
Accounts with no prior 3D task can receive the missing credits for one 512³ task, up to 150 trial credits. The allowance is granted once and expires after 7 days; later tasks use purchased credits, and failed tasks automatically return reserved credits.
What input images work best with trellis-2?
The site says TRELLIS.2 works best with clear subject images with alpha-masked foregrounds, handles various styles including photos, renders, and artwork, and recommends images with good lighting and clear object boundaries.
How many TRELLIS.2 generations does each plan include?
A 512³ generation uses 150 credits, 1024³ uses 300 credits, and 1536³ uses 500 credits, and every plan lists the exact maximum for each resolution before checkout.
