Abstract

We present GOATex, a diffusion-based method for 3D mesh texturing that generates high-quality textures for both exterior and interior surfaces. While existing methods perform well on visible regions, they inherently lack mechanisms to handle occluded interiors, resulting in incomplete textures and visible seams. To address this, we introduce an occlusion-aware texturing framework based on the concept of hit levels, which quantify the relative depth of mesh faces via multi-view ray casting. This allows us to partition mesh faces into ordered visibility layers, from outermost to innermost. We then apply a two-stage visibility control strategy that progressively reveals interior regions with structural coherence, followed by texturing each layer using a pretrained diffusion model. To seamlessly merge textures obtained across layers, we propose a soft UV-space blending technique that weighs each texture's contribution based on view-dependent visibility confidence. Empirical results demonstrate that GOATex consistently outperforms existing methods, producing seamless, high-fidelity textures across both visible and occluded surfaces. Unlike prior works, GOATex operates entirely without costly fine-tuning of a pretrained diffusion model and allows separate prompting for exterior and interior mesh regions, enabling fine-grained control over layered appearances.

Separate Prompt Conditioning for Inner and Outer Surfaces

A key advantage of GOATex is its ability to support distinct prompts for exterior and interior mesh regions—corresponding to hit level 1 and deeper layers, respectively—thanks to our progressive, layered texturing framework.

Inner Prompt:

An interior painted as a night sky mural with a comet trailing across the ceiling and nebula clouds around the edges.

Inner Prompt:

An interior gilded entirely in reflective gold leaf, creating a blinding, ornate enclosure.

Inner Prompt:

An interior illustrated in ink with an ancient map of the stars, seas, and lost kingdoms.

Inner Prompt:

Main Pipeline

teaser

(1) Our framework begins with superface construction, grouping fine-grained faces into coherent regions.

(2) We then assign each superface hit level by casting rays from multiple viewpoints, indicating its relative depth within the mesh.

(3) Based on these hit levels, we apply a visibility control strategy, combining residual face clustering with normal flipping and backface culling, to progressively reveal interior geometry without disrupting the object's structural integrity.

(4) For each hit level, we synthesize textures using a depth-conditioned multi-view diffusion (MVD) module.

(5) We employ a soft, visibility-weighted UV-blending strategy to merge textures across levels, ensuring seamless and coherent appearance.
