ComfyUI: Applying LoRAs for line drawings and Lego styles

ComfyUITry it →Watch full video →Urban Decoders ·

Demo summary

The user demonstrates stacking LoRA models in ComfyUI to transform buildings into line drawings or Lego-style structures using Flux Kontext.

Step-by-step

  1. Install the RG3 custom node to access the Power Lora node.
  2. Download the desired LoRA file and add it to your ComfyUI lora folder.
  3. Add the Power Lora node to your workflow.
  4. Select the LoRA within the node and set the strength to 1.
  5. Upload the image you want to stylize.
  6. Copy and paste the recommended prompt from the LoRA's source website.
  7. Run the workflow to generate the stylized output.

Options

  • Stack multiple LoRAs simultaneously using the Power Lora node
  • Adjust individual LoRA strengths to combine different styles
  • Source LoRAs from Hugging Face or Plugflower.com

Watch out for

  • CivitAI may be blocked in certain regions like the UK.
  • The line drawing LoRA may leave small gaps in the linework that require manual cleanup.

Tips

  • Filter for 'Flux context' when searching for compatible LoRAs on model sites.
  • Vectorize line drawing outputs in Adobe Illustrator for use in architectural diagrams.
  • Copy the specific prompt recommended by the LoRA creator for the best results.

Highlights

“This works for all the other laws in the same way.”
