-                                Paint3D is capable of producing high-resolution, lighting-less, and diverse 2K UV texture maps for untextured 3D meshes conditioned on text or image inputs.
+                                We present Paint3D, a novel coarse-to-fine generative framework that is capable of producing
+                            high-resolution, lighting-less, and diverse 2K UV texture maps for untextured 3D meshes
+                            conditioned on text or image inputs. The key challenge addressed is generating high-quality
+                            textures without embedded illumination information, which allows the textures to be
+                            re-lighted or re-edited within modern graphics pipelines. To achieve this, our method first
+                            leverages a pre-trained depth-aware 2D diffusion model to generate view-conditional images
+                            and perform multi-view texture fusion, producing an initial coarse texture map. However, as
+                            2D models cannot fully represent 3D shapes and disable lighting effects, the coarse texture
+                            map exhibits incomplete areas and illumination artifacts. To resolve this, we train separate
+                            UV Inpainting and UVHD diffusion models specialized for the shape-aware refinement of
+                            incomplete areas and the removal of illumination artifacts. Through this coarse-to-fine
+                            process, Paint3D can produce high-quality 2K UV textures that maintain semantic consistency
+                            while being lighting-less, significantly advancing the state-of-the-art in texturing 3D
+                            objects.
