ComfyUI Node: 🔢 CR Gradient Integer

🔢 CR Gradient Integer:

The CR Gradient Integer node is designed to generate a smooth transition of integer values over a specified range and duration. This node is particularly useful in animation and interpolation tasks where you need to create a gradual change in values between two points over time. By defining the start and end values, as well as the duration and current frame, the node calculates the appropriate integer value for the current frame, ensuring a seamless and visually appealing transition. This functionality is essential for creating dynamic and fluid animations, making it a valuable tool for AI artists looking to enhance their projects with smooth value transitions.

🔢 CR Gradient Integer Input Parameters:

start_value

The initial integer value from which the gradient will begin. This parameter sets the starting point of the transition. The value should be an integer, and it significantly impacts the initial state of the gradient. There is no explicit minimum or maximum value, but it should be within the range of typical integer values used in your project.

end_value

The final integer value at which the gradient will end. This parameter defines the endpoint of the transition. Like the start_value, it should be an integer and will determine the final state of the gradient. There is no explicit minimum or maximum value, but it should be within the range of typical integer values used in your project.

start_frame

The frame number at which the gradient transition should start. This parameter is crucial for timing the beginning of the transition. It should be an integer, and its value must be less than or equal to the current_frame to ensure the transition starts correctly.

frame_duration

The total number of frames over which the gradient transition will occur. This parameter defines the length of the transition period. It should be a positive integer, and its value will determine how quickly or slowly the transition happens.

current_frame

The current frame number for which the gradient value is being calculated. This parameter is essential for determining the current state of the gradient. It should be an integer, and its value must be within the range defined by start_frame and start_frame + frame_duration to ensure accurate gradient calculation.

gradient_profile

A profile that defines the shape of the gradient transition. This parameter allows for customization of the gradient's behavior, such as linear, ease-in, ease-out, etc. The specific options for this parameter depend on the implementation and available profiles in the system.

🔢 CR Gradient Integer Output Parameters:

int_out

The calculated integer value for the current frame based on the defined gradient. This output represents the current state of the gradient transition and is an integer value that changes smoothly from start_value to end_value over the specified frame_duration.

🔢 CR Gradient Integer Usage Tips:

• Ensure that the start_frame and current_frame parameters are set correctly to avoid unexpected behavior in the gradient transition.
• Use the gradient_profile parameter to customize the transition's behavior and achieve the desired visual effect.
• Adjust the frame_duration parameter to control the speed of the transition, with shorter durations resulting in faster changes and longer durations creating slower, more gradual transitions.

🔢 CR Gradient Integer Common Errors and Solutions:

"Current frame is less than start frame"

• Explanation: This error occurs when the current_frame parameter is set to a value less than the start_frame.
• Solution: Ensure that the current_frame is greater than or equal to the start_frame to start the gradient transition correctly.

"Current frame exceeds the duration"

• Explanation: This error occurs when the current_frame parameter is set to a value greater than start_frame + frame_duration.
• Solution: Adjust the current_frame to be within the range defined by start_frame and start_frame + frame_duration to ensure accurate gradient calculation.

"Invalid frame duration"

• Explanation: This error occurs when the frame_duration parameter is set to a non-positive value.
• Solution: Ensure that the frame_duration is a positive integer to define a valid transition period.
