Seed3D

Seed3D 2.0 is the next-generation high-precision 3D generation large model officially released by ByteDance on April 23, 2026, as an upgraded iteration of Seed3D 1.0. Building on the breakthroughs in end-to-end 3D model generation from single images and texture production achieved by its predecessor, Seed3D 2.0 has undergone comprehensive architectural upgrades focused on geometric accuracy and material quality, while significantly expanding the downstream usability of generated 3D content. It has reached state-of-the-art (SOTA) performance in both geometric structure generation and texture material production, setting a new benchmark for the generative 3D industry.

Core Features of Seed3D 2.0

Seed3D 2.0 introduces a groundbreaking Coarse-to-Fine two-stage generation strategy that decouples “overall structure” and “geometric details” for separate optimization. This innovation solves long-standing challenges in 3D generation, including sharp edges, thin-walled structures, and complex topologies, delivering far more precise geometric outputs than previous models. The complete geometric generation pipeline first produces a coarse mesh from image tokens through a DiT and decoder architecture, then refines the mesh using voxelized positional encoding and a second-stage DiT-decoder module.

For texture generation, Seed3D 2.0 adopts a unified PBR (Physically Based Rendering) generation model to jointly model complete PBR maps. It leverages a Mixture of Experts (MoE) architecture to enhance high-resolution material details and boundary precision, and integrates Vision-Language Model (VLM) priors to improve the stability and accuracy of material decomposition under unknown lighting conditions. This pipeline can generate multi-view albedo, metallic, and roughness maps that closely match real-world physical properties.

Beyond core geometry and texture generation, Seed3D 2.0 adds three critical advanced capabilities for practical deployment. It supports part-level segmentation and completion of 3D objects, enabling independent manipulation of inpidual components. It also provides articulated asset generation, producing 3D content with complete joint information compatible with standard formats. Additionally, it enables scene composition generation based on images, videos, or text prompts, building coherent and interactive 3D environments.

What Seed3D 2.0 Can Help You Achieve

Seed3D 2.0 transforms the traditional 3D content creation workflow, drastically reducing the time and technical threshold required for high-quality 3D asset production. It can convert a single 2D image into a detailed, textured 3D model in minutes, eliminating the need for manual modeling from scratch. The model generates physically accurate PBR textures that can be directly used in rendering pipelines, avoiding the tedious process of manual texture painting and material adjustment.

With its part-level segmentation capability, users can easily split generated 3D objects into functional components, modify inpidual parts, or replace them with other assets. The articulated generation feature creates 3D models with movable joints that can be directly imported into physical simulation engines for animation and interaction testing. For scene creation, Seed3D 2.0 can automatically arrange multiple 3D objects in a spatially reasonable layout based on text descriptions or video inputs, building complete 3D scenes ready for interactive simulation.
