ComfyUI Node: Curve From YAML

Curve From YAML:

The KfCurveFromYAML node is designed to create a keyframed curve from a YAML string. This node allows you to define complex animation curves using a human-readable YAML format, making it easier to specify and manage keyframes and their properties. By converting YAML data into a keyframed curve, this node provides a flexible and intuitive way to animate parameters over time. This can be particularly useful for AI artists who want to create smooth transitions and animations without delving into complex coding. The main goal of this node is to simplify the process of defining and using keyframed curves in your projects.

Curve From YAML Input Parameters:

yaml

The yaml parameter is a multiline string input that allows you to define the keyframed curve using YAML syntax. This input should contain the curve's keyframes, interpolation methods, and other properties. The default value provided is a basic example of a curve definition:

curve:

• • 0
• 0
• linear
• • 1
• 1 loop: false bounce: false duration: 1 label: foo

This example defines a simple linear curve from 0 to 1. The yaml parameter is essential for specifying the curve's behavior and properties, and it supports customization to fit various animation needs.

Curve From YAML Output Parameters:

KEYFRAMED_CURVE

The KEYFRAMED_CURVE output is the resulting keyframed curve object created from the provided YAML string. This output can be used in other nodes to animate parameters or control various aspects of your project. The keyframed curve encapsulates the defined keyframes, interpolation methods, and other properties, making it a versatile tool for creating dynamic animations.

Curve From YAML Usage Tips:

• Ensure your YAML string is correctly formatted and includes all necessary properties for the curve, such as keyframes, interpolation methods, and duration.
• Use the label property to give your curve a meaningful name, making it easier to identify and manage in complex projects.
• Experiment with different interpolation methods (e.g., linear, ease-in, ease-out) to achieve the desired animation effect.

Curve From YAML Common Errors and Solutions:

Invalid YAML format

• Explanation: The provided YAML string is not correctly formatted, causing a parsing error.
• Solution: Double-check the YAML syntax and ensure all key-value pairs and lists are properly indented and structured.

Missing required properties

• Explanation: The YAML string does not include all necessary properties for defining the curve.
• Solution: Ensure that your YAML string includes keyframes, interpolation methods, and other essential properties like loop, bounce, and duration.

Unsupported interpolation method

• Explanation: The YAML string specifies an interpolation method that is not supported by the node.
• Solution: Use supported interpolation methods such as linear, ease-in, or ease-out in your YAML string.
