AI总结:

SUPRA-Tex是一种基于解耦策略的3D生成方法,通过分离可见材质估计等任务,在公共数据集上训练后,在几何条件纹理生成等任务中达到SOTA性能,表现优于部分商业系统。

摘要:

单图像3D生成旨在为给定的3D网格赋予可重光照的材质,同时忠实保留参考图像的视觉细节。现有方法要么在融合不一致的多视图预测时引入伪影,要么在通过隐式图像特征条件保留精细细节方面存在困难。为解决这些挑战,我们提出SUPRA-Tex,其基于可见材质估计、表面对齐和观测引导的3D完成解耦的原则。这种分工使在有限3D数据上训练的3D生成器能够将其能力集中在保留可见证据和完成未观测表面上。具体而言,我们首先训练一个基于MLLM的图像编辑模型,以预测参考视图中分离光照的PBR贴图。然后将这些贴图投影到可见表面,并使用预训练的材质VAE编码器将其编码为原生观测潜变量,这些潜变量与生成目标的潜变量空间共享。交错流Transformer将这些潜变量作为固定的只读锚点,同时交替进行未观测区域和全表面更新,以生成完整的材质潜变量。该设计实现了与参考的超对齐,在可见区域提供“所见即所得”的保真度,并在未观测表面上实现连贯的完成。仅在公共数据集上训练的SUPRA-Tex在几何条件纹理生成和端到端资产生成中实现了SOTA性能,在野外图像上的表现与领先的商业系统相当甚至超过它们。项目页面:this https URL

英文摘要:

Single image 3D generation aims to dress a given 3D mesh with relightable materials while faithfully preserving the visual details of a reference image. Existing methods either introduce artifacts when fusing inconsistent multi-view predictions or struggle to preserve fine details through implicit image-feature conditioning. To resolve these challenges, we introduce SUPRA-Tex, built on the principle of decoupling visible-material estimation, surface alignment, and observation-guided 3D completion. This division of labor allows the 3D generator, trained on limited 3D data, to focus its capacity on preserving visible evidence and completing unobserved surfaces. Specifically, we first train an MLLM-based image editing model to predict lighting-separated PBR maps in the reference view. We then project these maps onto the visible surface and encode them with the pretrained material VAE encoder into native observation latents that share the generation target's latent space. An interleaved flow transformer holds these latents as fixed, read-only anchors while alternating unobserved-region and full-surface updates to generate complete material latents. This design achieves super-alignment with the reference, delivering What You See Is What You Get fidelity on visible regions and coherent completion on unobserved surfaces. Trained solely on public datasets, SUPRA-Tex achieves SOTA performance in both geometry-conditioned texturing and end-to-end asset generation, matching or even exceeding leading commercial systems on in-the-wild images.
