ComfyUI Node: Apply Ref Motion

Apply Ref Motion:

The ApplyRefMotionNode is designed to integrate reference motion data into a model, enhancing its ability to generate outputs that adhere to specific motion patterns or characteristics. This node is particularly useful for AI artists who want to apply motion references to their models, ensuring that the generated outputs follow desired motion dynamics. By leveraging reference latents and conditioning inputs, the node modifies the model's behavior to incorporate these references, providing more control over the motion aspects of the generated content. This can be especially beneficial in animation and video generation tasks where consistent and realistic motion is crucial.

Apply Ref Motion Input Parameters:

model

The model parameter represents the AI model that will be modified to incorporate the reference motion data. This is a required input and should be a pre-trained model that supports motion reference integration.

ref_latents

The ref_latents parameter contains the latent representations of the reference motion data. These latents are used to guide the model in generating outputs that follow the specified motion patterns. This is a required input and should be provided in the appropriate latent format.

enabled

The enabled parameter is a boolean that determines whether the reference motion application is active. If set to True, the node will apply the reference motion to the model. If set to False, the model will remain unchanged. The default value is True.

positive

The positive parameter is a conditioning input that provides positive examples or prompts to guide the model's behavior. This input helps the model understand the desired motion characteristics. It is a required input and should be provided in the appropriate conditioning format.

negative

The negative parameter is a conditioning input that provides negative examples or prompts to guide the model's behavior. This input helps the model understand what to avoid in the generated motion. It is a required input and should be provided in the appropriate conditioning format.

start_percent

The start_percent parameter is a float that specifies the starting point of the reference motion application as a percentage of the total motion duration. It ranges from 0.0 to 1.0, with a default value of 0.0. This parameter allows you to control when the reference motion starts influencing the model.

end_percent

The end_percent parameter is a float that specifies the ending point of the reference motion application as a percentage of the total motion duration. It ranges from 0.0 to 1.0, with a default value of 0.70. This parameter allows you to control when the reference motion stops influencing the model.

ref_settings

The ref_settings parameter contains the settings for the reference motion application. These settings define how the reference motion data is applied to the model. This is a required input and should be provided in the appropriate settings format.

Apply Ref Motion Output Parameters:

model

The model output is the modified AI model that has been updated to incorporate the reference motion data. This output allows you to use the model in subsequent nodes or processes, ensuring that the generated outputs follow the desired motion patterns.

Apply Ref Motion Usage Tips:

• Ensure that the ref_latents parameter is correctly prepared and matches the format expected by the model to avoid errors during execution.
• Adjust the start_percent and end_percent parameters to fine-tune the duration and influence of the reference motion on the model's output, optimizing the results for specific tasks.
• Use the enabled parameter to quickly toggle the reference motion application on and off, allowing you to compare the model's behavior with and without the reference motion.

Apply Ref Motion Common Errors and Solutions:

"Motion Reference latent must be at least as long as sample latent."

• Explanation: This error occurs when the length of the reference latents is shorter than the sample latents.
• Solution: Ensure that the reference latents provided in the ref_latents parameter are at least as long as the sample latents required by the model.

"Invalid conditioning input format."

• Explanation: This error occurs when the positive or negative conditioning inputs are not in the correct format.
• Solution: Verify that the conditioning inputs are provided in the appropriate format expected by the model and the node.

"Reference motion application is disabled."

• Explanation: This message indicates that the enabled parameter is set to False, so the reference motion is not being applied.
• Solution: Set the enabled parameter to True if you want to apply the reference motion to the model.
