ComfyUI Node: ADMD_LoadLora

ADMD_LoadLora:

The ADMD_LoadLora node is designed to facilitate the loading of LoRA (Low-Rank Adaptation) models into the AD Motion Director pipeline. This node allows you to specify a path to a LoRA file and adjust its strength, enabling fine-tuning of motion effects in your animations. By integrating LoRA models, you can enhance the motion dynamics of your animations, making them more expressive and tailored to your creative vision. The node also supports the optional inclusion of a previously loaded motion LoRA, allowing for cumulative effects and more complex motion dynamics. This functionality is particularly beneficial for AI artists looking to add nuanced motion details to their animated projects.

ADMD_LoadLora Input Parameters:

lora_path

The lora_path parameter is a string that specifies the file path to the LoRA model you wish to load. This parameter is mandatory and must be provided to ensure the node can locate and load the desired LoRA file. The path should be relative to the animatediff_motion_lora directory within your models directory. If the specified file does not exist, an error will be raised. This parameter does not support multiline input and defaults to an empty string.

strength

The strength parameter is a float that determines the intensity of the LoRA model's effect on the motion dynamics. It allows you to control how strongly the LoRA influences the animation, with a default value of 1.0. The value can range from 0.0 to 10.0, with a step size of 0.001, providing fine-grained control over the effect's strength. Adjusting this parameter can help you achieve the desired level of motion enhancement in your animations.

prev_motion_lora

The prev_motion_lora parameter is optional and accepts a MOTION_LORA type. This parameter allows you to include a previously loaded motion LoRA, enabling cumulative effects when multiple LoRA models are applied. If not provided, a new MotionLoraList will be created. This feature is useful for building complex motion dynamics by layering multiple LoRA effects.

ADMD_LoadLora Output Parameters:

MOTION_LORA

The output of the ADMD_LoadLora node is a MOTION_LORA type. This output represents the loaded LoRA model, including any previously loaded motion LoRA if provided. The MOTION_LORA can be used in subsequent nodes within the AD Motion Director pipeline to apply the specified motion dynamics to your animations. This output is essential for integrating the LoRA effects into your animation workflow, ensuring that the desired motion enhancements are applied.

ADMD_LoadLora Usage Tips:

• Ensure that the lora_path is correctly specified and points to a valid LoRA file within the animatediff_motion_lora directory to avoid file not found errors.
• Experiment with the strength parameter to find the optimal level of motion enhancement for your specific animation project. Start with the default value and adjust as needed.
• Utilize the prev_motion_lora parameter to layer multiple LoRA effects, creating more complex and nuanced motion dynamics in your animations.

ADMD_LoadLora Common Errors and Solutions:

Motion lora not found at <full_lora_path>

• Explanation: This error occurs when the specified LoRA file cannot be found at the provided path.
• Solution: Verify that the lora_path is correct and that the file exists in the animatediff_motion_lora directory. Ensure there are no typos in the file name or path.

An error occurred while loading a LoRA file: <error_message>

• Explanation: This error indicates that an exception was raised during the loading of the LoRA file.
• Solution: Check the error message for specific details. Common issues include file corruption or incompatible file formats. Ensure the LoRA file is valid and compatible with the AD Motion Director pipeline.
