A simple but powerful LoRA key converter for ComfyUI. This node is designed to help you convert LoRA models with old or non-standard key names to the new format, ensuring compatibility with the latest versions of ComfyUI and other platforms.
📝 This node also fixes issues with LoRA models trained and produced with FAL.AI, which may not work correctly in ComfyUI or with ComfyUI-nunchaku nodes.
If you are having issues with LoRA models trained with FAL.AI, this node can help. These models often have non-standard key names that can cause them to fail in ComfyUI. This node will automatically convert the keys to the correct format, allowing you to use them in your workflows.
- Batch Conversion: Convert a single LoRA file or an entire directory of LoRA files at once.
- Dry Run Mode: Simulate the conversion process without actually modifying any files, allowing you to see what changes will be made.
- Customizable Output: Specify a custom output directory and filename prefix for your converted files.
- Error Handling: The node will skip files that have already been converted and report any errors that occur during the conversion process.
