TRELLIS.2: Native and Compact Structured Latents for 3D Generation
Our 4B-parameter model generates high-resolution fully textured assets with exceptional fidelity and efficiency with vanilla DiTs. At the core is the native and compact structured latents, which push the frontiers of fidelity and compactness at the same time. Reconstruction accuracy v.s. Latent compactness Our method robustly handles complex structures, including open surfaces, non-manifold geometry, and enclosed interior structures, breaking the constraints of iso-surface fields. Our method can model arbitrary surface attributes such as Base Color, Roughness, Metallic, and Opacity (i.e., Transparency or Alpha channel), enabling Physically Based Rendering (PBR) and photorealistic relighting.
