  We introduce Meta 3D Gen (3DGen), a new state-of-the-art, fast pipeline for
text-to-3D asset generation. 3DGen offers 3D asset creation with high prompt
fidelity and high-quality 3D shapes and textures in under a minute. It supports
physically-based rendering (PBR), necessary for 3D asset relighting in
real-world applications. Additionally, 3DGen supports generative retexturing of
previously generated (or artist-created) 3D shapes using additional textual
inputs provided by the user. 3DGen integrates key technical components, Meta 3D
AssetGen and Meta 3D TextureGen, that we developed for text-to-3D and
text-to-texture generation, respectively. By combining their strengths, 3DGen
represents 3D objects simultaneously in three ways: in view space, in
volumetric space, and in UV (or texture) space. The integration of these two
techniques achieves a win rate of 68% with respect to the single-stage model.
We compare 3DGen to numerous industry baselines, and show that it outperforms
them in terms of prompt fidelity and visual quality for complex textual
prompts, while being significantly faster.
