UltraTex pushes multi-view diffusion to 2048 resolution with background token dropping and block-sparse attention, reaching up to 91.1x training speedup
UltraTex is an end-to-end multi-view diffusion framework that scales image-guided 3D texturing from 512/768 to 2048 resolution through Background Token Dropping, Block-Sparse Attention, and Foreground-Aware VAE Decoding, and it builds G-buffer TexVerse covering over 268,000 3D assets, achieving 20.6-91.1x training speedup and 22.3-74.6x end-to-end inference speedup within the dataset's common foreground-ratio range of 10%-30%.
