This node creates hook keyframes from a list of floating-point strength values, distributing them evenly between specified start and end percentages. It generates a sequence of keyframes where each strength value is assigned to a specific percentage position in the animation timeline. The node can either create a new keyframe group or add to an existing one, with an option to print the generated keyframes for debugging purposes.

Inputs

Parameter	Data Type	Required	Range	Description
floats_strength	FLOATS	Yes	-1 to ∞	A single float value or list of float values representing strength values for the keyframes (default: -1)
start_percent	FLOAT	Yes	0.0 to 1.0	The starting percentage position for the first keyframe in the timeline (default: 0.0)
end_percent	FLOAT	Yes	0.0 to 1.0	The ending percentage position for the last keyframe in the timeline (default: 1.0)
print_keyframes	BOOLEAN	Yes	True/False	When enabled, prints the generated keyframe information to the console (default: False)
prev_hook_kf	HOOK_KEYFRAMES	No	-	An existing hook keyframe group to add the new keyframes to, or creates a new group if not provided

Note: The floats_strength parameter accepts either a single float value or an iterable list of floats. The keyframes are distributed linearly between start_percent and end_percent based on the number of strength values provided.

Outputs

Output Name	Data Type	Description
HOOK_KF	HOOK_KEYFRAMES	A hook keyframe group containing the newly created keyframes, either as a new group or appended to the input keyframe group
