SEngine - SWORKS_TEAM LoRA Browser for ComfyUI

A ComfyUI plugin that provides a sidebar interface for browsing, downloading, and applying SWORKS_TEAM LoRAs from Civitai. Current implementation uses klein-9b and klein-9b-base models.

Features

• Sidebar Browser - Browse all SWORKS_TEAM LoRAs with image previews
• Tag Filtering - Filter LoRAs by tags using a multi-select dropdown
• Search - Search by name, trained words, or tags
• Auto-Download - LoRAs are automatically downloaded on first use
• Dynamic Node - Strength sliders appear on the node for each selected LoRA
• Overall Strength - Master strength slider (0.0 - 1.0) to control all LoRAs at once
• Reorder LoRAs - Change the order LoRAs are applied using up/down buttons
• Standard Storage - Downloads go to ComfyUI's models/loras/ folder
• Civitai Upload - One-click upload generated images to Civitai with:
  • Auto-extracted metadata (prompt, seed, sampler, CFG, steps)
  • Automatic LoRA resource tagging
  • Flux tool tagging with model name
  • ComfyUI tool tagging with SEngine configuration
  • Image-to-image composite support (shows source + generated images)

Installation

After installation, restart ComfyUI.

Requirements

• ComfyUI (recent version with sidebar support)
• Python packages (install via pip install -r requirements.txt):
  • Pillow (usually included with ComfyUI)
  • blurhash (for image upload)
  • numpy (usually included with ComfyUI)
  • requests (for Civitai upload)

Usage

1. Open the Sidebar

Click the bolt icon in ComfyUI's sidebar to open the SEngine panel.

2. Enter API Key

Enter your Civitai API key in the API Key field. This enables:

• Faster downloads
• Access to any restricted models

The API key is saved locally in your browser.

3. Browse and Select LoRAs

• LoRAs load automatically on startup
• Click the refresh button to update the list
• Use the tag dropdown to filter by category
• Use the search box to find specific LoRAs
• Click a LoRA to select/deselect it

4. Connect the Node

When you select your first LoRA, an SEngine LoRA Loader node is automatically created.

Connect it to your workflow:

[Load Diffusion Model] → MODEL → [SEngine LoRA Loader] → MODEL → [BasicGuider]

5. Adjust Strengths

• Overall Strength slider (0.0 - 1.0) controls the master effect of all LoRAs
• Each selected LoRA gets a strength slider on the node (0.0 - 2.0)
• Adjust in the sidebar or directly on the node
• Use up/down buttons in the sidebar to reorder LoRAs
• LoRAs set to 0.0 strength are effectively disabled

6. Run Your Workflow

• LoRAs are downloaded automatically if not already cached
• Download progress is shown in the sidebar
• Downloaded LoRAs are stored in ComfyUI/models/loras/

7. Upload to Civitai (Optional)

Share your generated images directly to Civitai:

1. Get your session cookie from Civitai:

   • Log into Civitai in your browser
   • Open DevTools (F12) → Application → Cookies
   • Copy the value of __Secure-civitai-token

2. Paste the cookie in the "Civitai session cookie" field at the bottom of the sidebar

3. Generate an image - the upload button will activate

4. Click "Upload Last Image" - this will:

   • Upload the image to Civitai
   • Create a post with auto-extracted metadata (prompt, seed, sampler, CFG, steps)
   • Tag the post with all LoRAs used in SEngine
   • Add Flux tool tag with the model name (from Load Diffusion Model node)
   • Add ComfyUI tool tag with SEngine configuration (overall strength + LoRA strengths)
   • Auto-publish the post

Image-to-Image Workflows

If your workflow includes Load Image nodes, SEngine will detect this as an image-to-image workflow and show a preview modal with options:

• Upload Composite - Creates a combined image showing source images → generated image
• Upload Original Only - Uploads just the generated image
• Cancel - Cancels the upload

The composite image displays source images stacked on the left with an arrow pointing to the generated image on the right.

Troubleshooting

LoRAs not loading

• Check the ComfyUI console for error messages
• Ensure your API key is correct

• Re-copy the __Secure-civitai-token cookie from Civitai
• Check the ComfyUI console for error messages
