CR Cycle Models (Legacy) Description

Automate model switching for dynamic animations with sequential cycling of models at specified intervals.

CR Cycle Models (Legacy):

The CR Cycle Models node is designed to facilitate the sequential cycling of different models during an animation or iterative process. This node allows you to switch between various models at specified intervals, enabling dynamic changes in the output based on the current frame of the animation. By leveraging this node, you can create more complex and varied animations without manually changing models, thus saving time and effort. The primary goal of this node is to automate the model switching process, ensuring smooth transitions and consistent application of different models throughout the animation sequence.

CR Cycle Models (Legacy) Input Parameters:

mode

The mode parameter determines the operational mode of the node. It can be set to "Off" or "Sequential". When set to "Off", the node will not perform any model cycling and will return the initial model and clip. When set to "Sequential", the node will cycle through the models based on the current frame and frame interval. This parameter is crucial for controlling whether the model cycling functionality is active or not. The available options are "Off" and "Sequential".

model

The model parameter represents the initial model to be used in the animation. This model serves as the starting point before any cycling occurs. It is essential for defining the base model that will be used when the mode is set to "Off" or at the beginning of the sequence when the mode is set to "Sequential".

clip

The clip parameter is associated with the initial model and is used in conjunction with it. Similar to the model parameter, it defines the base clip that will be used when the mode is set to "Off" or at the beginning of the sequence when the mode is set to "Sequential".

model_list

The model_list parameter is a list of models that will be cycled through during the animation. Each entry in the list should contain the model alias and the checkpoint name. This list is essential for defining the sequence of models that will be used when the mode is set to "Sequential". The length and content of this list directly impact the variety and complexity of the animation.

frame_interval

The frame_interval parameter specifies the number of frames between each model switch. It determines how frequently the node will cycle to the next model in the model_list. A smaller frame interval results in more frequent model changes, while a larger interval results in less frequent changes. This parameter is crucial for controlling the timing of model transitions.

loops

The loops parameter defines the number of times the model_list should be repeated during the animation. This allows for extended animations where the model sequence needs to be cycled multiple times. The value of this parameter directly affects the duration and repetition of the model cycling process.

current_frame

The current_frame parameter represents the current frame of the animation. It is used to calculate the index of the model to be used from the model_list based on the frame_interval. This parameter is essential for synchronizing the model cycling with the animation's progress.

CR Cycle Models (Legacy) Output Parameters:

model

The model output parameter represents the current model after cycling. It is the model that corresponds to the current frame based on the mode, model_list, frame_interval, and current_frame parameters. This output is crucial for ensuring that the correct model is applied at each frame of the animation.

clip

The clip output parameter is associated with the current model and is used in conjunction with it. Similar to the model output, it represents the clip that corresponds to the current frame based on the mode, model_list, frame_interval, and current_frame parameters.

show_help

The show_help output parameter provides a URL to the documentation or help page for the CR Cycle Models node. This is useful for users who need additional information or guidance on using the node effectively.

CR Cycle Models (Legacy) Usage Tips:

• To create smooth transitions between models, ensure that the frame_interval is set appropriately based on the length of your animation.
• Use the loops parameter to extend the duration of your animation by repeating the model sequence multiple times.
• Make sure your model_list is well-curated with models that complement each other to achieve the desired visual effects.

CR Cycle Models (Legacy) Common Errors and Solutions:

"IndexError: list index out of range"

• Explanation : This error occurs when the current_frame and frame_interval calculation results in an index that exceeds the length of the model_list.
• Solution : Ensure that the model_list is not empty and that the frame_interval and loops parameters are set correctly to avoid exceeding the list's bounds.

"FileNotFoundError: [Errno 2] No such file or directory"

• Explanation : This error occurs when the specified checkpoint name in the model_list cannot be found in the designated folder.
• Solution : Verify that all checkpoint names in the model_list are correct and that the corresponding files are located in the correct directory.

"TypeError: 'NoneType' object is not subscriptable"

• Explanation : This error occurs when the model_list is not properly initialized or is set to None.
• Solution : Ensure that the model_list parameter is correctly defined and contains valid entries before running the node.
