Overview

TRELLIS.2 is Microsoft’s 4B-parameter open-source image-to-3D model released in April 2026. The model generates 1536³ voxel-resolution 3D assets with full PBR (physically-based rendering) materials in a single forward pass. The architecture uses O-Voxel sparse voxel representations to support complex topologies and sharp features.

Timeline

  • 2026-04-28-AI-Digest — TRELLIS.2 released as open-source on r/LocalLLaMA, achieving 1536³ voxel resolution with full PBR texture support; sparse O-Voxel architecture enables complex topologies and sharp features on consumer hardware.

Key Developments

  1. High-Resolution Consumer 3D Generation: TRELLIS.2’s 1536³ voxel resolution with full PBR materials represents a significant jump in accessible 3D asset generation, enabling creators to produce production-grade textured models without expensive GPU farms.

  2. Sparse Voxel Architecture: The O-Voxel design innovation allows the model to run efficiently on consumer hardware despite the high output resolution, making sophisticated 3D generation accessible to local development workflows.
