ComfyUI Node: Wan Analyzer + Selective Loader V2

Wan Analyzer + Selective Loader V2:

The WanAnalyzerSelectiveLoaderV2 is a sophisticated tool designed to enhance the control and flexibility of working with Wan 2.2 LoRAs (Low-Rank Adaptations). This node combines the functionalities of an analyzer and a selective loader, allowing you to assess the impact of different transformer blocks within the model and adjust their influence individually. By providing a detailed block guide, it categorizes the 40 blocks into early, early-mid, mid-late, and late stages, enabling you to understand and manipulate the model's behavior at various processing stages. The node supports strength scheduling, a feature that lets you define the intensity of each block's contribution over time, using a simple format like 0:.2,.5:.8,1:1.0. This capability is particularly beneficial for fine-tuning the model's output, ensuring that you can achieve the desired artistic effects with precision.

Wan Analyzer + Selective Loader V2 Input Parameters:

block_strengths

The block_strengths parameter allows you to specify the strength of each block within the model. This parameter is crucial for determining how much influence each block has on the final output. You can define the strengths using a scheduling format, such as 0:.2,.5:.8,1:1.0, where each pair represents a point in time and the corresponding strength. This flexibility enables you to dynamically adjust the model's behavior, enhancing or diminishing the impact of specific blocks as needed. The parameter does not have a fixed minimum or maximum value, but it typically ranges from 0 to 1, with 0 meaning no influence and 1 meaning full influence.

block_selection

The block_selection parameter allows you to toggle individual transformer blocks on or off. This parameter is essential for controlling which parts of the LoRA are applied during processing. By selectively enabling or disabling blocks, you can focus the model's processing power on the most impactful areas, optimizing performance and output quality. The parameter accepts a list of block identifiers, such as block_0, block_1, etc., up to block_39, allowing for granular control over the model's operation.

Wan Analyzer + Selective Loader V2 Output Parameters:

analyzed_blocks

The analyzed_blocks output provides a detailed report on the impact of each block within the model. This output is crucial for understanding how different parts of the model contribute to the final result, allowing you to make informed decisions about block strengths and selections. The report includes metrics and insights that help you identify which blocks are most effective for your specific artistic goals.

adjusted_model

The adjusted_model output is the modified version of the original model, reflecting the changes made based on your block strengths and selections. This output is the final product that you can use for generating images or other creative outputs. It incorporates all the adjustments you've made, ensuring that the model behaves according to your specifications and artistic vision.

Wan Analyzer + Selective Loader V2 Usage Tips:

• Use the block guide to understand the role of each block and adjust their strengths accordingly to achieve the desired artistic effect.
• Experiment with different strength schedules to see how dynamic changes in block influence can enhance your creative outputs.
• Start by analyzing the blocks to identify which ones have the most impact, then selectively enable or disable blocks to optimize performance.

Wan Analyzer + Selective Loader V2 Common Errors and Solutions:

Invalid block identifier

• Explanation: This error occurs when a block identifier provided in the block_selection parameter does not exist or is misspelled.
• Solution: Double-check the block identifiers against the provided block guide and ensure they are correctly spelled and within the valid range (e.g., block_0 to block_39).

Strength schedule format error

• Explanation: This error arises when the strength schedule format is incorrect or improperly formatted.
• Solution: Ensure that the strength schedule follows the correct format, such as 0:.2,.5:.8,1:1.0, with each pair representing a time point and strength value.
