ComfyUI-LG_SamplingUtils is a user-friendly toolset designed to enhance your experience with ComfyUI. Created by LAOGOU-666, this extension provides practical sampling nodes to simplify operations. It focuses on advanced sampling techniques, especially for Flow Matching models such as ZImage and Lumina2.

This extension includes four powerful nodes that make sampling intuitive and efficient:

This node adds noise to timesteps during sampling. It helps produce diverse outputs, preventing the model from becoming too uniform.

Key Features:

• Two modes: sigma for traditional diffusion models and flow for Flow Matching models
• Adjustable noise strength for customized results
• Mask support for targeted effects
• Seed-based reproducibility for consistency

Parameters:

• mode: Select between sigma (multiplicative noise) or flow (additive noise)
• noise_strength: Control the intensity of the noise effect
• application_range: Define how broadly the noise applies

Optimize your sampling process with the Flow Matching Adjuster. This tool helps achieve the desired fluidity in output transitions.

Key Features:

• Dynamic adjustment of flow parameters
• Compatibility with ZImage and Lumina2 models
• Real-time feedback during adjustments

Parameters:

• flow_rate: Adjust the speed of flow matching
• transition_duration: Set the time for smooth transitions

Transform your output with the Enhanced Output Mapper. This node refines the final results of your sampling process.

Key Features:

• Custom templates for output format
• Options for different data representations
• Easy export to popular formats

Parameters:

• output_format: Choose how to export data (e.g., JSON, CSV)
• template_selection: Pick from pre-built or custom templates

Manage your settings with ease using the User Preferences Manager. This node allows you to save and load settings quickly.

Key Features:

• Simple interface for setting preferences
• Save/load functionality for user settings
• Backup options for data safety

Parameters:

• preference_file: Path to save settings
• auto_backup: Toggle for automatic backups
