ComfyUI Node: Create CFG Schedule Float List

Create CFG Schedule Float List:

The CreateCFGScheduleFloatList node is designed to generate a list of floating-point numbers that can be used to schedule parameters such as configuration (cfg) and lora scale per step in a process. This node is particularly useful for tasks that require gradual changes in parameter values over a series of steps, allowing for smooth transitions and precise control over the scheduling process. By providing a flexible mechanism to interpolate values between a start and end point, this node enables you to customize the behavior of your scheduling tasks, whether you need linear, ease-in, or ease-out interpolation. This capability is essential for applications where dynamic adjustments are necessary, such as in animation or video processing, where the gradual change of parameters can significantly impact the final output.

Create CFG Schedule Float List Input Parameters:

steps

The steps parameter defines the total number of steps over which the scheduling will occur. It determines the length of the list of floats that will be generated. The more steps you have, the finer the granularity of the scheduling process, allowing for more precise control over the parameter changes.

start_value

The start_value parameter specifies the initial value from which the scheduling will begin. This value is used as the starting point for interpolation and will be the first value in the list if the start_percent is set to 0.

end_value

The end_value parameter defines the final value to which the scheduling will progress. This value is used as the endpoint for interpolation and will be the last value in the list if the end_percent is set to 1.

default_value

The default_value parameter is used to fill the list of floats initially. It acts as a baseline value for all steps before any interpolation is applied. This value is particularly useful when you want to maintain a constant value outside the specified interpolation range.

interpolation

The interpolation parameter determines the method used to interpolate between the start_value and end_value. Options include "linear" for a straight-line interpolation, "ease_in" for a gradual start, and "ease_out" for a gradual end. This choice affects how smoothly the values transition from start to end.

start_percent

The start_percent parameter indicates the percentage of the total steps at which the interpolation should begin. It is expressed as a fraction of the total steps, allowing you to delay the start of the interpolation process.

end_percent

The end_percent parameter specifies the percentage of the total steps at which the interpolation should end. Like start_percent, it is expressed as a fraction of the total steps, allowing you to control when the interpolation process should conclude.

unique_id

The unique_id parameter is an optional identifier used to track the progress of the scheduling process. If provided, it can be used to send progress updates to a server or logging system, which is useful for monitoring and debugging purposes.

Create CFG Schedule Float List Output Parameters:

cfg_list

The cfg_list output parameter is a list of floats representing the scheduled values over the specified number of steps. This list reflects the interpolated values between the start_value and end_value according to the chosen interpolation method and the specified start and end percentages. It provides a detailed schedule that can be used to control various parameters dynamically over time.

Create CFG Schedule Float List Usage Tips:

• To achieve a smooth transition between values, choose the appropriate interpolation method based on your needs: "linear" for uniform changes, "ease_in" for a slow start, and "ease_out" for a slow end.
• Use the start_percent and end_percent parameters to control precisely when the interpolation should begin and end, allowing for flexibility in scheduling.

Create CFG Schedule Float List Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error may occur if the start_percent or end_percent values result in indices that exceed the list boundaries.
• Solution: Ensure that start_percent and end_percent are set within the range of 0 to 1, and that start_percent is less than or equal to end_percent.

TypeError: unsupported operand type(s) for -: 'NoneType' and 'int'

• Explanation: This error can happen if any of the input parameters are not properly initialized or are set to None.
• Solution: Verify that all input parameters are correctly set and initialized before executing the node.
