Microsoft TRELLIS.2 is an open-source 4B image-to-3D model for generating textured mesh assets from a single image. Best for 3D artists, game prototypers, and product mockups that need fast GLB-ready starting points. Microsoft TRELLIS.2 is a practical image-to-3D resource: give it a single image, and it can generate a textured 3D asset with PBR material channels. The official project reports about 3 seconds for 512^3 generation on an NVIDIA H100, with larger 1024^3 and 1536^3 modes taking longer. Use it when you need a fast first-pass asset for Blender, Unity, Unreal, product mockups, game prototypes, or 3D ideation. The project centers on O-Voxel, a field-free sparse voxel representation designed to handle arbitrary topology, open surfaces, non-manifold geometry, opacity, roughness, metallic, and base-color material attributes. Evaluate it before production use. The repository notes Linux support, CUDA requirements, and at least 24GB of NVIDIA GPU memory, with A100 and H100 verification. The model card also warns that raw meshes can still have small holes or artifacts and that the base model is not preference-aligned. Treat the output as a strong editable starting point, not a guaranteed final production mesh.
