scraed 29ed0b3da5 Add **kwargs to CFGGuider_LanPaint sampling methods
Updated the outer_sample and inner_sample method calls in CFGGuider_LanPaint to accept and forward arbitrary keyword arguments (**kwargs). This allows for greater flexibility and compatibility with future changes or additional parameters.

scraed 3d5aa3a3fa Add Hunyuan supports
Added new example workflows for Hunyuan, including images and JSON workflow files. Updated README with Hunyuan T2I inpainting instructions and links. Increased default LanPaint step size to 0.2 in nodes and advanced sampler, and refactored scale_latent_inpaint logic in lanpaint.py for improved compatibility.

**Warning**: LanPaint has degraded performance on distillation models, such as Flux.dev, due to a similar [issue with LORA training](https://medium.com/@zhiwangshi28/why-flux-lora-so-hard-to-train-and-how-to-overcome-it-a0c70bc59eaf). Please use low flux guidance (1.0-2.0) to mitigate this [issue](https://github.com/scraed/LanPaint/issues/30).
## How It Works
LanPaint uses Langevin Dynamics as "thinking" steps, which digs deeper into the diffusion process and allows the model to generate more consistent results.
LanPaint introduces "BIG score" that creates a **two-way alignment** between masked and unmasked areas. It continuously evaluates:
- *"Does the new content make sense with the existing elements?"*
- *"Do the existing elements support the new creation?"*
Based on this evaluation, LanPaint iteratively updates the noise in both the masked and unmasked regions.
LanPaint also implements an accurate, robust, and fast Langevin dynamics solver.
## Quickstart
1. **Install ComfyUI**: Follow the official [ComfyUI installation guide](https://docs.comfy.org/get_started) to set up ComfyUI on your system. Or ensure your ComfyUI version > 0.3.11.

Once installed, you'll find the LanPaint nodes under the "sampling" category in ComfyUI. Use them just like the default KSampler for high-quality inpainting!
## **How to Use Examples:**
1. Navigate to the **example** folder (i.e example_1), download all pictures.
2. Drag **InPainted_Drag_Me_to_ComfyUI.png** into ComfyUI to load the workflow.
3. Download the required model (i.e clicking **Model Used in This Example**).
4. Load the model in ComfyUI.
5. Upload **Masked_Load_Me_in_Loader.png** to the **"Load image"** node in the **"Mask image for inpainting"** group (second from left), or the **Prepare Image** node.
7. Queue the task, you will get inpainted results from LanPaint. Some example also gives you inpainted results from the following methods for comparison:
- **[VAE Encode for Inpainting](https://comfyanonymous.github.io/ComfyUI_examples/inpaint/)**
- **[Set Latent Noise Mask](https://comfyui-wiki.com/en/tutorial/basic/how-to-inpaint-an-image-in-comfyui)**
## Video Examples (Beta)
LanPaint now supports video inpainting with Wan 2.2, enabling you to seamlessly inpaint masked regions across video frames while maintaining temporal consistency.
**Note:** LanPaint supports video inpainting for longer sequences (e.g., 81 frames), but processing time increases significantly (please check the [Resource Consumption](#resource-consumption) section for details) and performance may become unstable. For optimal results and stability, we recommend limiting video inpainting to **40 frames or fewer**.

### Example Wan2.2: Partial InPaint(LanPaint K Sampler, 5 steps of thinking)
Sometimes we don't want to inpaint completely new content, but rather let the inpainted image reference the original image. One option to achieve this is to inpaint with an edit model like Qwen Image Edit. Another option is to perform a partial inpaint: allowing the diffusion process to start at some middle steps rather than from 0.

You need to follow the ComfyUI version of [Qwen Image workflow](https://docs.comfy.org/tutorials/image/qwen/qwen-image) to download and install the model.
The following examples utilize a random seed of 0 to generate a batch of 4 images for variance demonstration and fair comparison. (Note: Generating 4 images may exceed your GPU memory; please adjust the batch size as necessary.)

Check more for use cases like inpaint on [fine tuned models](https://github.com/scraed/LanPaint/issues/12#issuecomment-2938662021) and [face swapping](https://github.com/scraed/LanPaint/issues/12#issuecomment-2938723501), thanks to [Amazon90](https://github.com/Amazon90).
## **How to Use These Examples:**
1. Navigate to the **example** folder (i.e example_1) by clicking **View Workflow & Masks**, download all pictures.
2. Drag **InPainted_Drag_Me_to_ComfyUI.png** into ComfyUI to load the workflow.
3. Download the required model from Civitai by clicking **Model Used in This Example**.
4. Load the model into the **"Load Checkpoint"** node.
5. Upload **Original_No_Mask.png** to the **"Load image"** node in the **"Original Image"** group (far left).
6. Upload **Masked_Load_Me_in_Loader.png** to the **"Load image"** node in the **"Mask image for inpainting"** group (second from left).
7. Queue the task, you will get inpainted results from three methods:
- **[VAE Encode for Inpainting](https://comfyanonymous.github.io/ComfyUI_examples/inpaint/)** (middle),
- **[Set Latent Noise Mask](https://comfyui-wiki.com/en/tutorial/basic/how-to-inpaint-an-image-in-comfyui)** (second from right),
- **LanPaint** (far right).
8. You also get an output from "masked blend" node, which copy the original image and paste onto the unmasked part of output. It is useful if you want unmasked region to match original picture pixel perfectly.
Compare and explore the results from each method!

Increase **total number of sampling steps** (very important!), **LanPaint_NumSteps** (thinking iterations) or **LanPaint_Lambda** if the inpainted result does not meet your expectations.

Decrease **LanPaint_NumSteps** to accelerate generation! If you want better results but still need fewer steps, consider:

⚠️ **Notes**:
- For effective tuning, **fix the seed** and adjust parameters incrementally while observing the results. This helps isolate the impact of each setting. Better to do it with a batche of images to avoid overfitting on a single image.

"Cyberpunk-style Einstein portrait: He wears a sleek black coat with glowing cyan circuit patterns, silver-rimmed cybernetic glasses (lenses display faint data streams), and his hair has subtle neon blue highlights. His expression is calm, with a faint smile. Behind him: a dark, rain-washed cybercity backdrop—towering skyscrapers with flickering holographic ads, wet pavement reflecting neon pink/magenta lights. In front of him: giant, glowing white 3D text of \"LanPaint\", with electric blue energy pulses swirling around the equation. Cinematic lighting, hyper-detailed textures, rain droplets visible in the air."

"Cyberpunk-inspired portrait of a beautiful young woman with ethereal features: She has long, flowing silver hair with glowing purple neon streaks, wearing a form-fitting black leather jacket adorned with holographic circuit designs in electric blue, and augmented reality earrings that project faint digital fractals. Her eyes are piercing emerald green with subtle cybernetic enhancements showing data overlays, and her expression is mysterious yet alluring, with a subtle smirk. Behind her: a foggy, neon-lit futuristic alleyway—crumbling brick walls covered in vibrant graffiti and flickering LED signs, puddles on the ground reflecting turquoise and violet lights from overhead drones. Dramatic volumetric lighting, ultra-realistic details, mist particles in the air."
