ComfyUI Node: 📑 CR Value Scheduler

📑 CR Value Scheduler:

The CR Value Scheduler is a versatile node designed to manage and schedule values over a series of frames, making it an essential tool for animation and time-based value adjustments. This node allows you to define a schedule for values, which can be dynamically adjusted based on the current frame of your animation. By providing a default value and a schedule, the CR Value Scheduler ensures that your values change smoothly and predictably over time, enhancing the fluidity and precision of your animations. This node is particularly useful for AI artists who need to automate value changes without manually adjusting each frame, thereby saving time and reducing the potential for errors.

📑 CR Value Scheduler Input Parameters:

mode

The mode parameter determines the operational mode of the scheduler. When set to "Default Value," the scheduler is disabled, and the default value is used throughout. This parameter is crucial for toggling between using a predefined schedule and a constant value. The available options are "Default Value" and "Scheduled Value."

current_frame

The current_frame parameter specifies the current frame number in the animation sequence. This parameter is essential for determining the value at a specific point in time based on the provided schedule. It accepts integer values starting from 0.

schedule_alias

The schedule_alias parameter is a string identifier for the schedule being used. This alias helps in managing and referencing different schedules, especially when multiple schedules are in use.

default_value

The default_value parameter sets the fallback value used when the scheduler is disabled or when no specific value is defined for the current frame. This parameter ensures that there is always a valid output, preventing disruptions in the animation. It accepts both integer and float values.

schedule_format

The schedule_format parameter defines the format of the schedule, specifying how the values are structured and interpreted. This parameter is important for correctly parsing and applying the schedule to the animation.

schedule

The schedule parameter contains the actual schedule data, which is a series of keyframes and corresponding values. This parameter is used to dynamically adjust the output value based on the current frame. It accepts a structured format that aligns with the schedule_format.

📑 CR Value Scheduler Output Parameters:

int_out

The int_out parameter is the integer representation of the scheduled value for the current frame. This output is useful for scenarios where integer values are required, ensuring compatibility with various systems and processes.

float_out

The float_out parameter is the float representation of the scheduled value for the current frame. This output provides a more precise value, which is essential for fine-tuned adjustments and smooth transitions in animations.

show_help

The show_help parameter provides a URL link to the documentation and help resources for the CR Value Scheduler. This output is valuable for users who need additional guidance or troubleshooting information.

📑 CR Value Scheduler Usage Tips:

• To ensure smooth transitions, carefully define your schedule with appropriate keyframes and values.
• Use the default_value parameter to set a fallback value that maintains consistency when the schedule is not in use.
• Regularly check the show_help link for updates and additional tips on using the CR Value Scheduler effectively.

📑 CR Value Scheduler Common Errors and Solutions:

No frame 0 found in schedule. Starting with default value at frame 0

• Explanation: This warning indicates that the schedule does not contain a value for frame 0, so the default value is used instead.
• Solution: Ensure that your schedule includes a keyframe for frame 0 to avoid this warning and ensure accurate value scheduling from the start.

Invalid params: <params>

• Explanation: This warning occurs when the parameters provided in the schedule are not valid numbers.
• Solution: Check your schedule data to ensure all values are correctly formatted as numbers. Correct any invalid entries to resolve this issue.
