RuYi-Nodes
A lightweight collection of practical custom nodes for ComfyUI.
面向 ComfyUI 的轻量实用自定义节点合集。
RuYi-Nodes currently focuses on two core workflows: visual Multi-LoRA management and image comparison/saving. A lightweight STRING preview node is also included as a supporting utility.
RuYi-Nodes 当前优先提供两类核心能力:可视化 Multi-LoRA 管理与图像对比/保存,并附带轻量的 STRING 文本监视工具。

Included nodes
| Node | Input | Output | Purpose |
| --- | --- | --- | --- |
| RuYi multi-Lora-loader | MODEL, CLIP | MODEL, CLIP, trigger_words | Load and visually manage multiple LoRAs with independent MODEL / CLIP strengths. |
| RuYi multi-Lora-loader (model only) | MODEL | MODEL, trigger_words | Load multiple LoRAs into MODEL only; useful for Krea2 / Flux-style workflows. |
| RuYi image-compare | Dynamic IMAGE inputs | — | Compare any two connected images, inspect them and save them with independent rules. |
| RuYi text-preview | STRING | STRING | Display the complete input STRING after execution and pass it through unchanged. |
Visual Multi-LoRA Loader
The RuYi Multi-LoRA loaders are designed to keep large LoRA stacks readable and manageable inside a single node.
Key features:
- Add, remove, reorder and enable/disable LoRAs independently.
- Full loader supports independent MODEL and CLIP strengths.
- Model-only loader is intended for workflows where LoRAs are applied only to MODEL / UNET.
- In-node preview thumbnails when metadata/preview information is available.
- Searchable LoRA picker with separate Folder and Base model filters.
- Per-node Show N LoRAs viewport control (
3by default,0= unlimited). - Optional
trigger_wordsSTRING output with de-duplication across enabled LoRAs. - Per-LoRA Output trigger toggle determines whether that LoRA contributes trigger words.
- Metadata-aware display for usage tips, notes, source links, base model and recommended weights.
- English and Simplified Chinese UI.
Recommended companion: ComfyUI-Lora-Manager
RuYi-Nodes works independently for normal multi-LoRA loading.
For preview images, trigger words, base-model information, recommended weights, notes, usage tips and source links, ComfyUI-Lora-Manager is recommended. RuYi-Nodes reads the .metadata.json sidecar files generated by LoRA Manager.
Note: LoRA Manager is only recommended for metadata-aware LoRA features. RuYi image-compare does not depend on LoRA Manager.
Expected sidecar layout:
my_lora.safetensors
my_lora.metadata.json
my_lora.jpeg

If metadata is unavailable, normal LoRA loading still works.
LoRA Picker
Search and filter LoRAs by Folder or Base model, with previews when available.

Trigger-word output
Both LoRA loaders expose an optional trigger_words STRING output.
For each enabled LoRA, Output trigger determines whether its trigger words are included. Trigger words from selected entries are combined and de-duplicated.
Leaving trigger_words unconnected is valid and does not affect LoRA loading.
A common prompt workflow is:
Main prompt STRING ───────────┐
├─ STRING concatenate / combine ──> final prompt STRING
RuYi trigger_words STRING ───┘
│
└─> RuYi text-preview
Krea2 / model-only workflow
For Krea2-style workflows where LoRAs are applied to MODEL only, use:
MODEL / UNET

MODEL
Keep the text encoder / CLIP path separate unless your workflow specifically requires otherwise.
Image Compare & Save
RuYi image-compare is a visual terminal node for comparing multiple image outputs without repeatedly rewiring a two-image compare node.

Comparison
- Connect one or more IMAGE outputs. A new IMAGE input is added automatically as connections grow.
- Use the A and B dropdowns to select any two connected images.
- Choose a comparison mode:
- Compare mode: Wipe — move the pointer horizontally over the preview to change the split position.
- Compare mode: Click — click the preview to switch between A and B.
- The image list below the preview handles naming, information and saving; A/B selection remains in the top dropdowns.
Each image entry shows:
- Preview thumbnail.
- Display name used inside the node and A/B selectors.
- Independent Save name / path template.
- Resolution and PNG file size.
- Per-image Auto save toggle.
- Per-image Save button.
Display names and save names are independent. For example, an image may display as Second pass while being saved with a different filename rule.
Media Assets and workflow metadata
Image Compare outputs are exposed through ComfyUI's standard image-output channel, so generated comparison candidates appear in Media Assets → Generated and task/output history.
Media Asset PNGs are kept separate from the node-local A/B preview cache. Re-running the same Image Compare node can therefore replace its previous Compare previews without invalidating earlier Media Assets/history entries; those asset copies remain standard ComfyUI temporary assets and follow ComfyUI's own lifecycle.
The redundant native image preview is suppressed inside the node itself, leaving the custom A/B comparison interface as the primary preview.
PNG previews/saves preserve ComfyUI prompt/workflow metadata when metadata is enabled. A saved PNG can therefore be dragged back into ComfyUI to restore its workflow and generation information.
Save / Auto save
If Save name does not contain an explicit folder, images are saved under:
ComfyUI/output/RuYi-Compare/
Default save-name template:
%display_name-date:yyyy-MM-dd_HHmmss%
RuYi filename variables:
User fields:
%display_name% %save_name%
Auto-generated:
%index% %input% %frame% %date:yyyy-MM-dd_HHmmss%
Relative subfolder example:
Compare/%display_name-date:yyyy-MM-dd_HHmmss%
which saves under:
ComfyUI/output/RuYi-Compare/Compare/
Absolute Windows path example:
C:\YourFolder\%display_name-date:yyyy-MM-dd_HHmmss%
Repeated filenames are protected from overwrite by adding a numeric suffix.
When an input image actually changes after a new execution, the previous save-status message for that image is cleared automatically.
Thumbnail context menu: full-resolution image actions
Right-click a candidate thumbnail for:
- Save as... — choose a destination using the system/browser save flow and save the full-resolution source image.
- Copy image — copy the full-resolution source image to the clipboard.
These actions are separate from the RuYi Save button: Save follows the per-image Save-name/path template, while Save as... is an interactive system save operation.

包含的节点
| 节点 | 输入 | 输出 | 用途 |
| --- | --- | --- | --- |
| RuYi 多 LoRA 加载器 | MODEL、CLIP | MODEL、CLIP、trigger_words | 在一个节点中可视化管理多个 LoRA,并分别控制 MODEL / CLIP 权重。 |
| RuYi 多 LoRA 加载器(仅模型) | MODEL | MODEL、trigger_words | 只向 MODEL 加载多个 LoRA,适合 Krea2 / Flux 一类仅模型 LoRA 工作流。 |
| RuYi 图像对比 | 动态 IMAGE 输入 | — | 从多个输入中选择任意两张进行 A/B 对比、检查与独立保存。 |
| RuYi 文本监视 | STRING | STRING | 执行后显示完整输入文本,并将 STRING 原样继续输出。 |
可视化 Multi-LoRA 加载器
RuYi Multi-LoRA 加载器的目标是在一个节点中保持较大的 LoRA 堆栈仍然清晰、可管理。
主要功能:
- 独立添加、删除、排序、启用/停用每个 LoRA。
- 完整版可分别设置 MODEL 与 CLIP 权重。
- 仅模型版本适合 LoRA 只应用到 MODEL / UNET 的工作流。
- 可用时直接在节点中显示 LoRA 预览封面。
- LoRA 选择器支持搜索,并分别按文件夹与基础模型筛选。
- 每个节点可独立设置显示 N 个 LoRA(默认
3,0表示不限高度)。 - 可选
trigger_wordsSTRING 输出,并对多个已启用 LoRA 的触发词自动去重。 - 每个 LoRA 的输出触发词开关决定它是否参与最终触发词输出。
- 可显示使用说明、附加备注、来源链接、基础模型与推荐权重等元数据。
- 支持英文 / 简体中文界面。
推荐配套:ComfyUI-Lora-Manager
RuYi-Nodes 本身可以独立完成正常的多 LoRA 加载。
如需预览图、触发词、基础模型信息、推荐权重、使用说明、附加备注和来源链接,推荐配合 ComfyUI-Lora-Manager 使用。RuYi-Nodes 会读取 LoRA Manager 生成的 .metadata.json sidecar 文件。
注意: LoRA Manager 只推荐用于 LoRA 元数据相关功能,RuYi 图像对比不依赖 LoRA Manager。
预期 sidecar 结构:
my_lora.safetensors
my_lora.metadata.json
my_lora.jpeg

即使没有元数据,正常 LoRA 加载仍然可以使用。
LoRA 选择器
可按文件夹或基础模型搜索和筛选 LoRA,并在可用时显示预览图。

触发词输出
两个 LoRA 加载器都会提供可选的 trigger_words STRING 输出。
对于每个已启用 LoRA,输出触发词决定其触发词是否加入最终 STRING。多个 LoRA 的触发词会合并并自动去重。
trigger_words 不连接也不会影响 LoRA 本身的加载。
一种常见连接方式:
主提示词 STRING ─────────────┐
├─ STRING 合并节点 ──> 最终提示词 STRING
RuYi trigger_words STRING ───┘
│
└─> RuYi 文本监视
Krea2 / 仅模型工作流
对于 Krea2 一类只需要把 LoRA 应用到 MODEL 的工作流,建议使用:
MODEL / UNET
│
▼
RuYi 多 LoRA 加载器(仅模型)
│
▼
MODEL
文本编码器 / CLIP 路径保持独立,除非具体工作流另有要求。
图像对比与保存
RuYi 图像对比是用于快速比较多个图像输出的可视化终端节点,不需要为了比较不同图片反复重新连接普通双图对比节点。

图像对比
- 连接一个或多个 IMAGE 输出;随着连接增加,节点会自动增加新的 IMAGE 输入。
- 通过顶部 A / B 下拉列表,从所有已连接图片中自由选择任意两张。
- 两种对比方式:
- 对比方式:滑动 — 在预览区左右移动鼠标改变分割位置。
- 对比方式:点击 — 点击预览区在 A / B 两张图片之间切换。
- 下方图片列表负责信息、命名和保存管理;A/B 选择仍由顶部下拉列表完成。
每张图片项目显示:
- 图片缩略图。
- 图像名称 — 用于节点内部显示和 A/B 下拉列表。
- 独立的保存文件名 / 路径模板。
- 分辨率和 PNG 文件体积。
- 每张图片独立的自动保存开关。
- 每张图片独立的保存按钮。
图像名称与保存文件名互相独立。例如节点中可以显示为“二采输出”,实际保存时使用另一套文件名规则。
媒体资产与工作流元数据
图像对比结果通过 ComfyUI 标准图片输出通道注册,因此候选图会出现在 媒体资产 → 已生成 以及任务/输出历史中。
媒体资产 PNG 与节点内部的 A/B 对比预览缓存彼此独立。因此同一个图像对比节点再次执行时,仍可清理上一轮 Compare 预览,而不会使此前的媒体资产/历史记录失效;资产副本继续作为 ComfyUI 标准临时资产,由 ComfyUI 自己管理生命周期。
节点内部会抑制 ComfyUI 默认的重复图片预览,只保留 RuYi 自己的 A/B 对比界面作为主要预览区域。
在没有关闭 ComfyUI metadata 的情况下,RuYi 生成/保存的 PNG 会保留 prompt 与 workflow 等 ComfyUI 元数据。将保存的 PNG 拖回 ComfyUI,可以恢复对应工作流和生成信息。
保存 / 自动保存
如果保存文件名没有指定目录,默认保存到:
ComfyUI/output/RuYi-Compare/
默认保存模板:
%display_name-date:yyyy-MM-dd_HHmmss%
RuYi 文件名变量:
用户填写:
%display_name% %save_name%
自动生成:
%index% %input% %frame% %date:yyyy-MM-dd_HHmmss%
相对子目录示例:
对比结果/%display_name-date:yyyy-MM-dd_HHmmss%
保存到:
ComfyUI/output/RuYi-Compare/对比结果/
Windows 绝对路径示例:
C:\YourFolder\%display_name-date:yyyy-MM-dd_HHmmss%
重复文件名不会覆盖已有图片,而是自动追加数字后缀。
当某个输入在新一轮工作流执行后真正变成新的图像内容时,该图片之前显示的保存状态提示会自动清除。
缩略图右键:原图操作
右键候选图片的缩略图可以使用:
- 另存为 — 使用系统/浏览器保存流程选择位置,并保存该候选项对应的原始分辨率图片。
- 复制图片 — 将该候选项对应的原始分辨率图片复制到剪贴板。
它们与节点里的 保存按钮用途不同:保存遵循当前图片的“保存文件名/路径模板”;另存为则是交互式的系统另存操作。
