ComfyUI Node: Parameter Group + Curve (addition)

Parameter Group + Curve (addition):

The KfPGroupCurveAdd node is designed to facilitate the addition of a keyframed curve to a parameter group, effectively combining their values. This node is particularly useful for AI artists who want to manipulate and enhance their animations or procedural art by adding dynamic curves to parameter groups. By using this node, you can seamlessly integrate a keyframed curve into an existing parameter group, allowing for more complex and nuanced control over your animations. The primary goal of this node is to provide a straightforward method for combining curves and parameter groups, thereby expanding the creative possibilities available to you.

Parameter Group + Curve (addition) Input Parameters:

parameter_group

The parameter_group input parameter expects a parameter group object, which is a collection of parameters that can be manipulated together. This parameter is required and must be provided as an input. The parameter group serves as the base to which the keyframed curve will be added. By combining the parameter group with the curve, you can achieve more intricate and detailed animations. There are no specific minimum or maximum values for this parameter, but it must be a valid parameter group object.

curve

The curve input parameter expects a keyframed curve object, which represents a series of values over time. This parameter is also required and must be provided as an input. The keyframed curve will be added to the parameter group, allowing you to introduce dynamic changes and variations to the parameters within the group. Similar to the parameter_group parameter, there are no specific minimum or maximum values for this parameter, but it must be a valid keyframed curve object.

Parameter Group + Curve (addition) Output Parameters:

PARAMETER_GROUP

The output parameter is a PARAMETER_GROUP, which is the result of adding the keyframed curve to the input parameter group. This combined parameter group can then be used in subsequent nodes or processes to drive animations or procedural art. The output parameter group retains all the original parameters from the input group, but with the added influence of the keyframed curve, providing enhanced control and flexibility.

Parameter Group + Curve (addition) Usage Tips:

• Ensure that both the parameter_group and curve inputs are valid and correctly formatted to avoid errors during execution.
• Use this node to add subtle variations and dynamic changes to your parameter groups, enhancing the overall complexity and realism of your animations.
• Experiment with different keyframed curves to see how they affect the parameter group, allowing you to fine-tune the results to match your creative vision.

Parameter Group + Curve (addition) Common Errors and Solutions:

Invalid parameter group input

• Explanation: This error occurs when the parameter_group input is not a valid parameter group object.
• Solution: Ensure that the parameter_group input is correctly formatted and is a valid parameter group object.

Invalid curve input

• Explanation: This error occurs when the curve input is not a valid keyframed curve object.
• Solution: Ensure that the curve input is correctly formatted and is a valid keyframed curve object.

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

• Explanation: This error occurs when the addition operation between the parameter group and the curve is not supported.
• Solution: Verify that both inputs are of the correct types and that they support the addition operation. If the issue persists, check for any updates or patches that might address this compatibility issue.
