Step1X-3D
Step1X-3D combines a geometry model with a texture model. The geometry path uses a VAE and diffusion transformer; the texture path builds on SDXL and aligns views through geometry.
Inspect shape before texture
The architecture generates geometry before it synthesizes texture. The project also describes transfer of two-dimensional controls, including LoRA, to texture generation.StepFun Step1X-3D model card
Review the mesh as an asset
Practical guidance. A strong rendered view does not prove that a mesh is ready for animation or manufacturing. Inspect hidden surfaces, topology, scale and texture seams in the downstream tool before using the asset.
