Microsoft TRELLIS

Microsoft TRELLIS is an open generative model for turning images into high-fidelity, fully textured 3D assets. TRELLIS.2 uses a compact structured 3D representation to handle complex topology, sharp features, and physically based materials while generating assets at resolutions up to 1536³.

Key features

• High-fidelity image-to-3D asset generation
• Full PBR materials and complex topology support
• Pretrained 4B-parameter model weights
• Python pipeline for local and research workflows
• Exports generated meshes for downstream 3D tools

TRELLIS is aimed at researchers, technical artists, and developers who want an open model they can run and integrate into custom 3D pipelines.
