ComfyUI Node: Object Add Shape Keys

Object Add Shape Keys:

The Object_AddShapeKeys node is designed to add shape keys to a 3D object in Blender, which are essential for creating complex animations and morphing effects. Shape keys, also known as morph targets, allow you to store different shapes of a mesh and interpolate between them, enabling smooth transitions and deformations. This node simplifies the process by allowing you to specify multiple shape keys at once and determine whether they should be created from the current mix of shapes. This functionality is particularly useful for AI artists looking to automate and streamline the creation of dynamic and expressive 3D models.

Object Add Shape Keys Input Parameters:

shape_keys

This parameter takes a string of comma-separated names for the shape keys you want to add to the object. Each name represents a new shape key that will be created. The default value is "key1,key2", and you can list as many shape keys as needed. This parameter is crucial for defining the specific deformations you want to store in the object.

from_mix

This boolean parameter determines whether the new shape keys should be created from the current mix of existing shape keys. If set to True, the new shape keys will be based on the current state of the object's shape keys. The default value is False. This option is useful when you want to capture the current deformation of the object as a new shape key.

Object Add Shape Keys Output Parameters:

This node does not have explicit output parameters. Instead, it modifies the input object by adding the specified shape keys to it. The changes are directly applied to the object within Blender, making the new shape keys available for further manipulation and animation.

Object Add Shape Keys Usage Tips:

• Ensure that the object you are working with is selected and active in Blender before running this node.
• Use descriptive names for your shape keys to easily identify them later when animating or modifying the object.
• If you want to capture the current deformation of the object as a new shape key, set the from_mix parameter to True.

Object Add Shape Keys Common Errors and Solutions:

"The shape key {name} does not exist on the object."

• Explanation: This error occurs when you try to add a shape key that already exists on the object.
• Solution: Ensure that the shape key names you provide are unique and do not conflict with existing shape keys on the object.

"The object does not have any shape keys."

• Explanation: This error occurs when the object does not have any shape keys, and you attempt to create a new shape key from the current mix.
• Solution: Make sure the object has at least one shape key before setting the from_mix parameter to True. If necessary, add an initial shape key manually in Blender.
