ComfyUI Node: Curve_1 + Curve_2

Curve_1 + Curve_2:

The KfCurvesAdd node is designed to perform arithmetic addition on two keyframed curves, resulting in a new curve that represents the sum of the input curves. This node is particularly useful for AI artists who need to combine multiple animation curves or parameter variations into a single, cohesive curve. By leveraging this node, you can seamlessly blend different motion paths or parameter changes, enhancing the fluidity and complexity of your animations. The primary goal of the KfCurvesAdd node is to simplify the process of curve manipulation, making it easier to achieve desired animation effects without manually adjusting each curve.

Curve_1 + Curve_2 Input Parameters:

curve_1

curve_1 is the first keyframed curve that you want to add. This parameter is essential as it serves as one of the two operands in the addition operation. The input must be of type KEYFRAMED_CURVE, and it is required to be provided. This curve represents the initial set of keyframes that will be combined with the second curve to produce the final output.

curve_2

curve_2 is the second keyframed curve that you want to add to the first curve. Similar to curve_1, this parameter is also of type KEYFRAMED_CURVE and is required. This curve provides the additional keyframes that will be summed with those of curve_1, resulting in a new curve that encapsulates the combined motion or parameter changes.

Curve_1 + Curve_2 Output Parameters:

KEYFRAMED_CURVE

The output of the KfCurvesAdd node is a single KEYFRAMED_CURVE that represents the sum of curve_1 and curve_2. This output curve contains the combined keyframes from both input curves, allowing you to use it in subsequent nodes or animations. The resulting curve can be used to drive various parameters or animations, providing a more complex and nuanced motion path.

Curve_1 + Curve_2 Usage Tips:

• Ensure that both input curves (curve_1 and curve_2) are properly keyframed and have compatible time ranges to achieve a smooth addition.
• Use this node to blend different animation effects, such as combining a base motion curve with a secondary curve that adds subtle variations or details.
• Experiment with different combinations of curves to create unique and dynamic animations that would be difficult to achieve manually.

Curve_1 + Curve_2 Common Errors and Solutions:

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

• Explanation: This error occurs when one or both of the input curves are not provided or are None.
• Solution: Ensure that both curve_1 and curve_2 are correctly specified and are of type KEYFRAMED_CURVE.

ValueError: Mismatched curve lengths

• Explanation: This error happens when the input curves have different lengths or incompatible keyframe timings.
• Solution: Verify that both input curves have matching time ranges and keyframe intervals to ensure a smooth addition.

AttributeError: 'Curve' object has no attribute '__add__'

• Explanation: This error indicates that the input objects are not of the correct type or do not support the addition operation.
• Solution: Confirm that both curve_1 and curve_2 are valid KEYFRAMED_CURVE objects and are not corrupted or improperly defined.
