New Open-Source AI Texturing for 3D Models at 2K Resolution
Good geometry still needs good textures. UltraTex is a new AI texturing framework that uses a reference image to generate detailed textures for an existing 3D model, working across six views at 2048×2048 resolution.
The focus is on preserving small surface details that tend to get lost in lower-resolution texturing pipelines, while keeping the generated appearance aligned with the geometry.
A few highlights:
- 2K multi-view generation for sharper texture details.
- Image-guided texturing, using a reference to guide the model’s appearance.
- Albedo generation, plus a separate metallic–roughness prediction branch with the FLUX.2 version.
- Training and inference code released, with downloadable weights.
- A dedicated inference script for AI-generated meshes.
The efficiency trick is pretty straightforward: stop spending so much compute on empty background. UltraTex removes background tokens and reduces unnecessary attention calculations between the remaining tokens.
The authors report 22.3–74.6× faster inference than their dense baseline on tested samples. Those benchmarks use an NVIDIA H200, so they don’t tell us how fast it will run on a regular desktop GPU.
For anyone working with AI-generated assets, this is a project worth testing for the texturing stage.
