ReAge3D: Re-Aging 3D Faces with View Consistency
Pith reviewed 2026-06-27 01:40 UTC · model grok-4.3
The pith
Re-aging 3D faces achieves detailed identity-preserving results by propagating 2D diffusion edits from a frontal pivot view to ensure multi-view consistency.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Training a diffusion re-aging model on synthetic pairs and then using a Masked-DiffReaging process to reconstruct non-frontal views from a re-aged frontal pivot produces a consistent multi-view image set that supervises optimization of a highly detailed, identity-preserving 3D re-aged face representation.
What carries the argument
The Masked-DiffReaging process, which injects existing content at every step of the diffusion process to keep reconstructed regions coherent with already-edited pixels during center-out propagation.
If this is right
- Enables smooth, fine-grained control over age transformations in 3D face models.
- Outperforms existing 3D editing techniques both visually and quantitatively.
- Prevents over-smoothing of subtle age-related details that arise from view inconsistencies.
- Produces highly detailed and identity-preserving re-aged 3D representations.
Where Pith is reading between the lines
- The same propagation approach could extend to other facial attribute edits such as expression or lighting changes in 3D.
- Performance may improve further if the 2D model were retrained on real paired aging data instead of synthetic pairs.
- Consistent re-aged 3D outputs could support downstream tasks like age-progressed animation or virtual aging simulations.
Load-bearing premise
A 2D diffusion model trained only on synthetically generated image pairs will produce identity-preserving re-aging results that remain coherent when propagated across multiple views via warping and Masked-DiffReaging, allowing those views to reliably supervise 3D optimization.
What would settle it
Rendered novel views of the final 3D model would display visible blurring, identity changes, or mismatched age features relative to the re-aged input views.

read the original abstract
We present a novel framework for realistic and controllable 3D face re-aging which produces highly detailed, identity-preserving results. Existing 3D editing methods, while effective for coarse semantic changes, are not well suited for re-aging, as even small inconsistencies across re-aged 2D views can lead to over-smoothing of subtle but perceptually important age-related details. To address this challenge, we first introduce a 2D diffusion-based re-aging model, DiffReaging, trained on synthetically generated image pairs. We further propose a center-out editing propagation strategy that leverages this re-aging model to reconstruct multi-view-consistent re-aged images. Specifically, starting from a re-aged frontal pivot view, we reconstruct the remaining views through warping and our proposed Masked-DiffReaging process. By injecting existing content at every step of the diffusion process, Masked-DiffReaging ensures that the reconstructed regions remain coherent with existing pixels. The resulting consistent set of re-aged views supervises the optimization of the re-aged 3D representation. Our method outperforms existing 3D editing techniques both visually and quantitatively, enabling smooth, fine-grained control over age transformations in 3D face models.

Referee Report
Summary. The paper presents ReAge3D, a framework for realistic and controllable 3D face re-aging. It introduces DiffReaging, a 2D diffusion model trained on synthetically generated image pairs, and a center-out editing propagation strategy that starts from a re-aged frontal view and uses warping plus Masked-DiffReaging (with content injection during diffusion) to produce multi-view consistent re-aged images. These images then supervise optimization of a re-aged 3D representation. The method claims visual and quantitative superiority over existing 3D editing techniques for fine-grained age control without over-smoothing.
Significance. If the central claims hold, the work would represent a meaningful advance in 3D face editing by solving the specific problem of view inconsistency in diffusion-based re-aging, which leads to loss of subtle age details. This could enable more practical applications in graphics, animation, and biometrics where identity-preserving, controllable 3D aging is needed.
major comments (2)
- [Abstract] Abstract: the central claim that DiffReaging trained exclusively on synthetic image pairs produces identity-preserving, view-coherent outputs that can supervise 3D optimization without over-smoothing is load-bearing, yet the abstract (and the provided description) gives no information on synthetic pair generation, real-data validation, or ablations showing that synthetic training captures aging variability; this directly affects whether the outperformance claim can be accepted.
- [Abstract] Masked-DiffReaging description: the mechanism of 'injecting existing content at every step' is presented as ensuring coherence, but without a precise definition of the mask schedule, injection strength, or quantitative analysis of drift in fine age details across propagated views, it is unclear whether the propagation step actually prevents the over-smoothing the paper seeks to avoid.

Referee: [Abstract] Abstract: the central claim that DiffReaging trained exclusively on synthetic image pairs produces identity-preserving, view-coherent outputs that can supervise 3D optimization without over-smoothing is load-bearing, yet the abstract (and the provided description) gives no information on synthetic pair generation, real-data validation, or ablations showing that synthetic training captures aging variability; this directly affects whether the outperformance claim can be accepted.
Authors: We agree that the abstract is too concise on these supporting elements. The full manuscript details the synthetic pair generation process, reports evaluations on real face data, and presents ablations on aging variability capture. We will revise the abstract to add a brief statement on the synthetic training approach and its validation to better ground the central claims. revision: yes

Authors: We agree that the abstract lacks sufficient precision on the Masked-DiffReaging parameters and analysis. The manuscript provides the mask schedule, injection strength, and quantitative drift metrics in the methods and experiments sections. We will revise the abstract to include a concise description of the injection mechanism and its role in preserving age details. revision: yes
Circularity Check
No significant circularity; derivation is self-contained
full rationale
The provided abstract and description outline a pipeline of training DiffReaging on synthetic image pairs followed by a center-out warping and Masked-DiffReaging propagation to produce multi-view supervision for 3D optimization. No equations, fitted parameters, or self-citations are exhibited that reduce any claimed prediction or result to its own inputs by construction. The method introduces new components (synthetic training, masking injection) whose outputs are not tautologically equivalent to the inputs, satisfying the criteria for an independent derivation chain.
