    🚀 Usage in a workflow

    Node outputs:

    • Positive Prompt (STRING)
    • Negative Prompt (STRING)
    • Image (IMAGE tensor, downloaded if a connection is active)
    • Info (STRING, formatted JSON metadata)

    💡 Tip: Connect the Image output only if you want the preview to be downloaded as a tensor. This saves resources when you don’t need it.

    🧹 Clear LoRA Name — Utility Node for ComfyUI

    The Clear LoRA Name node is a lightweight utility designed to work seamlessly with the Civitai Discovery Hub extension. Its purpose is to clean prompts by automatically removing any embedded LoRA tags of the form <lora:Some_LoRA_Name:0.7> or similar variations.

    comfyui_civitai_gallery_001

    🔧 How it works

    • Inputs:
      • positive_prompt (optional)
      • negative_prompt (optional)
    • Process:
      • The node parses both prompts.
      • All <lora:...> tags are stripped out.
      • The remaining text is cleaned to remove extra spaces or artifacts.
    • Outputs:
      • positive_prompt (cleaned)
      • negative_prompt (cleaned)

    🚀 Why it’s useful with Civitai Discovery Hub

    When browsing images in Civitai Discovery Hub, many prompts include references to LoRAs that might not be available locally. Using these raw prompts in your workflow can trigger errors or produce unexpected results.
    By placing the Clear LoRA Name node after the Hub’s prompt outputs:

    • You keep the descriptive part of the prompt intact.
    • You remove external dependencies (<lora:...>).
    • Your workflow becomes portable, clean, and reproducible.

    🖥️ UI Features

    • On/Off toggle: quickly enable/disable the cleaning process without deleting the node.
    • Compact and minimal: fits smoothly into your workflow as a utility step.

    ✅ Example

    Original prompt from Civitai Discovery Hub:
    A cinematic portrait of a warrior <lora:FluxHeroXL:0.8> in a snowy landscape

    After Clear LoRA Name:
    A cinematic portrait of a warrior in a snowy landscape

    ❓ FAQ

    Q. I scroll to the bottom and nothing loads, what should I do?
    Stay at the bottom: the “near-bottom” mechanism automatically triggers loading. If the network is slow, wait until the current batch finishes (check the status). If it still seems stuck, scroll slightly up and back down to re-trigger.

    Q. Favorites don’t appear immediately in “Favorites only” mode.
    The list is refreshed automatically, but if there is still a delay, use Refresh to sync.

    Q. Why do some videos take time to show a preview?
    Videos load metadata first. The preview appears after a micro-seek. On slow networks, a fallback forces full loading.
