ComfyUI Node: LoRA Hook Keyframes From List 🎭🅐🅓

LoRA Hook Keyframes From List 🎭🅐🅓:

The ADE_LoraHookKeyframeFromStrengthList node is designed to create a series of LoRA (Low-Rank Adaptation) hook keyframes based on a list of strength values. This node is particularly useful for AI artists who want to animate or condition their models with varying strengths over time. By providing a list of strength values, this node interpolates these values over a specified percentage range, creating keyframes that can be used to control the influence of LoRA hooks dynamically. This allows for more nuanced and controlled animations or conditioning effects, enhancing the creative possibilities for AI-generated art.

LoRA Hook Keyframes From List 🎭🅐🅓 Input Parameters:

strengths_float

This parameter accepts either a single float value or a list of float values representing the strengths to be used for creating the keyframes. If a single float is provided, it will be converted into a list with one element. The strengths determine the influence of each keyframe. The default value is -1, with a minimum step of 0.001.

start_percent

This float parameter specifies the starting percentage of the interpolation range. It defines where the first keyframe will be placed in the timeline. The value ranges from 0.0 to 1.0, with a default of 0.0 and a step of 0.001.

end_percent

This float parameter specifies the ending percentage of the interpolation range. It defines where the last keyframe will be placed in the timeline. The value ranges from 0.0 to 1.0, with a default of 1.0 and a step of 0.001.

print_keyframes

This boolean parameter determines whether the created keyframes should be printed to the log for debugging or informational purposes. The default value is False.

prev_hook_kf

This optional parameter accepts a LORA_HOOK_KEYFRAMES object, which represents a group of previously created keyframes. If provided, the new keyframes will be added to this group. If not provided, a new group will be created.

LoRA Hook Keyframes From List 🎭🅐🅓 Output Parameters:

HOOK_KF

This output parameter returns a LORA_HOOK_KEYFRAMES object, which contains the group of keyframes created based on the provided strength values and interpolation range. This object can be used in subsequent nodes to apply the keyframes to the model.

LoRA Hook Keyframes From List 🎭🅐🅓 Usage Tips:

• To create a smooth transition of strengths over time, provide a list of strength values that gradually increase or decrease.
• Use the start_percent and end_percent parameters to control the timing of the keyframes within your animation or conditioning sequence.
• Enable the print_keyframes option to verify the created keyframes and ensure they are placed correctly in the timeline.

LoRA Hook Keyframes From List 🎭🅐🅓 Common Errors and Solutions:

strengths_float must be either an iterable input or a float

• Explanation: This error occurs when the strengths_float parameter is neither a float nor an iterable (like a list).
• Solution: Ensure that you provide either a single float value or a list of float values for the strengths_float parameter.

prev_hook_kf is not of type LORA_HOOK_KEYFRAMES

• Explanation: This error occurs when the prev_hook_kf parameter is not a LORA_HOOK_KEYFRAMES object.
• Solution: Ensure that the prev_hook_kf parameter, if provided, is a valid LORA_HOOK_KEYFRAMES object. If you are not sure, you can omit this parameter to create a new group of keyframes.
