LoRA is a fantastic way to customize and fine-tune image generation in ComfyUI, whether you're using SD1.5, SDXL, or Flux. With LoRAs, you can easily personalize characters, outfits, or objects in your creations. In this post, I'll walk you through how to add LoRAs to ComfyUI using MimicPC, making the whole process a breeze.

- All nodes and models are ready to go.
- No manual setup required.
- Error-free—just click and run!
Step 1: Download LoRA
Before incorporating LoRA into your workflow, you’ll need to download the file:
- Locate LoRA Files: Download LoRA files from sources like Hugging Face or copy the download link.
- Prepare for Upload: In MimicPC, uploading LoRA files is simple and efficient.
Step 2: Upload LoRA to MimicPC
Once you have your LoRA file or URL, follow these steps to upload it into MimicPC:
- Navigate to Storage Manager: In MimicPC, go to Storage Manage and navigate to
storage > model > loras
. - Upload the File: You can either upload the LoRA file from your device or use the URL upload option to link the file from an external source.
- Restart the Application: After the upload, restart ComfyUI within MimicPC to ensure it detects the new LoRA files. If the application is already running, a simple restart will suffice.
Step 3: Load the Default Workflow in ComfyUI
Once inside the ComfyUI environment, start by loading the default workflow. This step sets the foundational framework for incorporating LoRA. MimicPC simplifies this by providing a ready-to-use workflow, so manual setup is minimized.
Step 4: Add the LoRA Node for SD1.5/SDXL
Now it’s time to incorporate the LoRA node into your workflow for SD1.5/SDXL:
- Load LoRA Node: In ComfyUI, double-click on the workspace or right-click to choose
Add Node > Loaders > Load LoRA
. This will allow you to add the LoRA node. - Configure LoRA Settings: Once the node is added, set the
lora_name
to reference the LoRA file you uploaded in theMimicPC > storage > model > loras
directory. Adjust thestrength_model
andstrength_clip
values to determine how strongly LoRA impacts the diffusion and CLIP models.
Step 5: Connect the LoRA Node
Next, integrate the LoRA node into your workflow:
- Position the Node: Place the LoRA node between the diffusion model and the CLIP nodes in your workflow.
- Link the Nodes: Connect the input/output of the LoRA node to the corresponding parts of your workflow to complete the setup.
Step 6: Test Your Workflow
After setting up the node, perform a test run:
- Generate an Image: This will help ensure that LoRA is correctly integrated into your workflow.
- Adjust the Strength: If needed, tweak the
strength_model
andstrength_clip
values for optimal results. You can also incorporate trigger words into your prompts for finer control.
Step 7 (Optional): LoRA Stacking
If one LoRA isn’t sufficient, you can combine multiple LoRAs for more advanced outputs:
- Use LoRA Stacker: In the Efficiency Nodes custom node, you can load multiple LoRAs.
- Individual Strength Adjustment: Fine-tune the strength of each LoRA for the desired effect.

Additional Step for Flux: Adding LoRA in Flux
Flux has its own dedicated nodes, so the process for adding LoRA requires an additional step:
- Reload Flux Nodes: Before adding LoRA to Flux workflows, you need to reload the Flux-specific nodes. This ensures that the Flux environment is properly set up.
- Add LoRA Node to Flux Workflow: Once the Flux nodes are loaded, you can follow the same steps as above to incorporate the LoRA node. Place the LoRA node between the diffusion model and CLIP nodes in your Flux workflow.
- Test and Adjust: As with SD1.5/SDXL, generate an image and adjust the strength settings for the LoRA to ensure optimal results.
Conclusion
Wrapping it all up, using LoRA with ComfyUI in MimicPC really makes the whole workflow smooth, whether you're working with SD1.5, SDXL, or Flux. Adding a single LoRA or even stacking multiple ones is super easy and straightforward. For Flux, you’ll just need to reload its specific nodes, but after that, it’s basically the same as with SD1.5/SDXL. With these simple steps, you’ll be opening up a world of creative possibilities for your image generation projects!
