Repair distorted faces and upscale images to 4K resolution.

Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning — you still choose inputs, prompts, and settings.

Why RunComfy first
- Fewer missing-node surprises — run the graph in a managed environment before you mirror it locally.
- Quick GPU tryout — useful if your local VRAM or install time is the bottleneck.
- Matches the published JSON — the zip follows the same runnable workflow you can open on RunComfy.

When downloading for local ComfyUI makes sense — you want full control over models on disk, batch scripting, or offline runs.

How to use (local ComfyUI)
1. Load inputs (images/video/audio) in the marked loader nodes.
2. Set prompts, resolution, and seeds; start with a short test run.
3. Export from the Save / Write nodes shown in the graph.

Expectations — First run may pull large weights; cloud runs may require a free RunComfy account.

Overview

Updated 6/16/2025: ComfyUI version updated to v0.3.39 for improved stability and compatibility. The Flux Upscaler with TTP Tile technology solves the common problem of distorted faces in AI-generated images. This specialized workflow combines tile-based processing with Flux's powerful image enhancement to repair facial features while upscaling resolution to 4K. The process preserves overall composition while selectively redrawing problematic areas, making it ideal for fixing small, distorted faces in otherwise good compositions. Compatible with various model bases for different facial styles.

Important nodes:

• High-Precision Face Restore:

• 4K Image Upscaling:

• Tile-Based Patch Enhancement:
