ComfyUI Node: External Lora (ComfyUI Deploy)

External Lora (ComfyUI Deploy):

The ComfyUIDeployExternalLora node is designed to facilitate the integration of external Lora models into the ComfyUI environment. This node allows you to either download a Lora model from a specified URL or use a default Lora model already available in your system. By automating the download and integration process, this node simplifies the workflow for AI artists, enabling them to quickly and efficiently incorporate new Lora models into their projects. The primary goal of this node is to enhance the flexibility and expand the creative possibilities within the ComfyUI framework by providing easy access to external Lora models.

External Lora (ComfyUI Deploy) Input Parameters:

input_id

The input_id parameter is a string that specifies the URL from which the Lora model should be downloaded. If the URL is valid and starts with "http", the node will download the Lora model from this URL and save it to the designated folder. This parameter is crucial for fetching external Lora models and integrating them into the ComfyUI environment. There are no specific minimum or maximum values for this parameter, but it must be a valid URL.

default_lora_name

The default_lora_name parameter is an optional string that specifies the name of a default Lora model to be used if no URL is provided or if the URL does not start with "http". This parameter allows you to use a pre-existing Lora model without the need for downloading a new one. If this parameter is not provided, the node will rely solely on the input_id parameter. There are no specific minimum or maximum values for this parameter, but it should be a valid Lora model name available in your system.

External Lora (ComfyUI Deploy) Output Parameters:

unique_filename

The unique_filename output parameter is a string that represents the name of the downloaded Lora model file. This filename is generated uniquely using a UUID to avoid conflicts with existing files. This output is crucial for identifying and accessing the newly downloaded Lora model within the ComfyUI environment. If the input_id parameter is a valid URL, this output will contain the unique filename of the downloaded model.

default_lora_name

The default_lora_name output parameter is a string that represents the name of the default Lora model used when no URL is provided or when the URL does not start with "http". This output is essential for identifying and accessing the pre-existing Lora model within the ComfyUI environment. If the input_id parameter is not a valid URL, this output will contain the name of the default Lora model.

External Lora (ComfyUI Deploy) Usage Tips:

• Ensure that the input_id parameter is a valid URL starting with "http" to successfully download an external Lora model.
• Use the default_lora_name parameter to specify a pre-existing Lora model if you do not wish to download a new one.
• Verify that the destination folder for Lora models is correctly configured in your ComfyUI environment to avoid any file path issues.
