顺序加载循环读取透明通道掩码返回torch张量
按顺序从目录逐张加载图片（每次一张），支持常见格式并提取透明通道为掩码，末尾自动循环，输出torch张量、掩码和文件路径。
💡 用于按序为ComfyUI流水线逐帧提供图像、掩码和路径进行处理。

📂 LoadLoopImagesFromDir – ComfyUI Node

A ComfyUI custom node for loading images sequentially from a directory.

🔹 Features

  • Loads one image per call, automatically moves to the next.
  • Loops back to the first image when reaching the end.
  • Supports .jpg, .jpeg, .png, .webp formats.
  • Extracts masks from images with alpha channels.
  • Returns a torch tensor image, mask, and file path.

    • 🛠 Node Inputs

    | Name | Type | Default | Description |

    |————-|——–|———|————-|

    | directory | String | "" | Path to folder with images. |

    | load_always | Boolean | False | Forces reload every call. |

    📤 Node Outputs

    | Name | Type | Description |

    |———–|————|————-|

    | IMAGE | Tensor | Loaded image as a torch tensor. |

    | MASK | Tensor | Mask (alpha channel) or blank mask. |

    | FILE PATH | String | Full path to the loaded image. |

    🔄 How It Works

  • Reads all valid images in the directory.
  • Sorts the list alphabetically.
  • Loads the next image each time the node runs.
  • Loops back to the first image when reaching the end.
  • Returns the image, mask, and path.

    • 🏗 Installation

    1️⃣ Make sure ComfyUI is installed.

    2️⃣ Clone this node in the custom_nodes folder.

    “`

    git clone https://github.com/alessandrozonta/Comfyui-LoopLoader.git

    “`

    3️⃣ Restart ComfyUI.

    ⚠️ Errors & Debugging

  • Directory not found → Check the folder path.
  • No images found → Ensure there are valid image files.
  • Mask is empty → Only images with alpha channels will have masks.
