【チェッカーズ Best Performance on NHK】レッツゴーヤング　冬号 Vol.2

A streamlined Z Image inpainting workflow using ZImageFunControlnet for ControlNet-based inpainting. Compared to the full version, this is a simplified pipeline without LoRA stacking, memory management nodes, translation, or SeedVR2 upscaling — ideal for sharing and distribution.

Detailed Stage Breakdown

1. Model Loading Pipeline

2. ControlNet Inpainting (ZImageFunControlnet)

This is the core difference from the first workflow. Instead of InpaintModelConditioning, this workflow uses a ControlNet-based approach.

Connection details:

model ← EasyCache output (base Z Image model)
model_patch ← ModelPatchLoaderCustom (ControlNet weights)
vae ← VAELoader
inpaint_image ← InpaintPreprocessor output
mask ← LoadImage mask output
image input is not connected (unused for inpainting mode)

3. CLIP & Text Processing

NOTE: Unlike the full version, there is no translation switch or text preview node. Enter prompts directly in English.

4. Differential Diffusion & Sampling

5. Sampling Settings

IMPORTANT: denoise=1 here because the ControlNet and DifferentialDiffusion handle the blending — the mask determines what changes, not the denoise value.

6. Decoding & Output

No memory management or upscale nodes in this version. Single output image.

Key Differences from Z Image Inpaint I

Usage Instructions

Basic Usage

Prepare Image & Mask
- Load image into the LoadImage node.
- Use Open Mask Editor to paint the area to inpaint.
Input Prompt
- Enter prompt directly in CLIPTextEncode in English.
Adjust Parameters
- ZImageFunControlnet strength: Adjust ControlNet influence (default 1).
- DifferentialDiffusionAdvanced threshold: Controls mask expansion (default 1.1).
- ModelSamplingAuraFlow shift: Adjusts sigma schedule (default 3).
- KSampler steps: More steps = higher quality but slower.
Execute
- Click Queue Prompt.
- One image will be saved.
