UltraTex: Unleashing 2K Multi-View Diffusion for 3D Texturing

Summary

UltraTex proposes an efficient pipeline for 2K multi‑view diffusion‑based 3D texturing by dropping background tokens, using block‑sparse attention, and a foreground‑aware VAE decoder. The method yields 20‑91× training and 22‑75× inference speedups while preserving fine‑grained texture detail.

  • Background Token Dropping removes background pixels before the DiT backbone, cutting token count dramatically.
  • Block‑Sparse Attention limits attention computation to foreground tokens, further reducing memory and latency.
  • Foreground‑Aware VAE Decoding reconstructs high‑resolution views without artifacts despite foreground‑only processing.
  • TexVerse dataset provides 268k ultra‑high‑resolution multi‑view renders to train 2K diffusion models.

Graphics engineers and diffusion researchers should care because it makes high‑resolution 3D texturing practical at scale.

    Video DeltaNet (VDN) replaces full‑softmax attention in video diffusion models with a hybrid: per‑frame local Softmax for fine detail and a bidirectional linear memory (Video Delta Attention) for long‑range context. A teacher‑alignment schedule injects the linear branch into a pretrained MiniMax H3 model, preserving Softmax for text/audio streams. On eight NVIDIA B200 GPUs VDN‑H3 denoises a 14.3‑…

    Mira-Scene proposes a compositional 3D scene reconstruction pipeline that replaces sparse pose regression with a dense Canonical Coordinate Map (CCM) linking image pixels to bounded object space. Coupled with a diffusion transformer, it achieves up to 40% higher 3D‑IoU than prior methods without scene‑level layout annotations.

    VC-Attention introduces a training‑free low‑bit attention pipeline for diffusion transformers. It smooths value tensors via lightweight online clustering (V‑Smooth) and quantizes only the residual after subtracting block means, restoring the mean from the softmax row sum. It also replaces the FP32 softmax exponential with a fused FP8 cast (ExpCast‑FP8) that maps log‑scores directly to E4M3 probab…

    The paper investigates why video diffusion models often break physical laws, pinpointing excessive spatial decay from Rotary Position Embedding (RoPE) as the culprit. By analyzing cross‑attention trajectories and self‑attention patterns, the authors identify specific attention heads that drive motion planning. They propose a lightweight fix: scaling RoPE frequency per denoising step, which empiri…
