TRELLIS.2 – AI Image-to-3D Model Generator

No. trellis-2.com is an independent third-party image-to-3D service. It is not Microsoft, not affiliated with Microsoft, and not the official TRELLIS.2 project site. Microsoft publishes the open-source model on GitHub; this site provides its own hosted generator, billing, and support.

TRELLIS.2 is an open-source 4B-parameter AI model published by Microsoft Research that converts a single image into a 3D starting asset. It uses 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, not a Microsoft website.

The system works by encoding images through a vision encoder and generating 3D content using a flow-matching transformer. It uses a Sparse Compression VAE with 16× spatial downsampling to create compact latent representations. The O-Voxel structure encodes both geometry and PBR appearance simultaneously.

You can create 3D starting assets from product photos, artwork, characters, objects, and more. Review topology, scale, materials, and printability before using a generated GLB in games, VR/AR, product visualization, or 3D-printing workflows.

TRELLIS.2 supports 512³, 1024³, and 1536³ output levels. This hosted service uses a managed provider queue, so completion time varies with resolution, image complexity, and provider load.

TRELLIS.2 directly exports 3D models in GLB (Binary glTF) format with embedded PBR textures. For PLY, download the GLB and use the separate browser converter; PLY is not a direct generator output.

Yes, TRELLIS.2 supports transparency through its alpha channel in PBR materials. It can generate translucent and transparent objects like glass, windows, and see-through materials. The O-Voxel structure naturally handles alpha transparency.

TRELLIS.2 is unique because it uses native 3D VAEs instead of multi-view diffusion methods. It directly generates 3D structure with the O-Voxel representation, enabling arbitrary topology, thin geometry, and transparent surfaces. Full PBR materials are produced in a single generation pass.

Create an account at trellis-2.com and upload a clear image. Accounts with no prior 3D task can try one 512³ task with a trial allowance. Later tasks and higher resolutions use purchased credits.

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; failed tasks automatically return reserved credits.

TRELLIS.2 works best with clear subject images with alpha-masked foregrounds. It handles various styles including photos, renders, and artwork. For best results, use images with good lighting and clear object boundaries.
