ComfyUI_experiments
These are experimental custom nodes for ComfyUI. Install by copying .py files to the custom_nodes folder, and they\'ll appear under custom_node_experiments/. Features include: sampler_tonemap.py with ModelSamplerTonemapNoiseTest for tonemapping noise during sampling to allow higher CFG values; sampler_rescalecfg.py implementing Rescale Classifier - Free Guidance; advanced_model_merging.py offering block - level model merging; sdxl_model_merging.py for SDXL base model merging; and reference_only.py with an implementation of "reference only controlnet" and sample workflows.

Description
Experimental Custom Nodes for ComfyUI
To install these experimental features, simply copy the .py files into your custom_nodes folder.
The nodes will appear under: custom_node_experiments/
sampler_tonemap.py
Introduces ModelSamplerTonemapNoiseTest - a node that applies basic tonemapping to noise during sampling. This allows higher CFG values without image distortion. Tip: Reduce the multiplier when increasing CFG.
sampler_rescalecfg.py
Implements the Rescale Classifier-Free Guidance technique from this research paper: arXiv:2305.08891
advanced_model_merging.py
Provides block-level model merging functionality for advanced users.
sdxl_model_merging.py
Specialized node for merging SDXL base models.
reference_only.py
Contains an implementation of the "reference only controlnet". Sample workflows are available in the workflows directory.
