Some experimental custom nodes for ComfyUI

Copy the .py files to your custom_nodes directory to use them.

They will show up in: custom_node_experiments/

sampler_tonemap.py

contains ModelSamplerTonemapNoiseTest a node that makes the sampler use a simple tonemapping algorithm to tonemap the noise. It will let you use higher CFG without breaking the image. To using higher CFG lower the multiplier value.

sampler_rescalecfg.py

contains an implementation of the Rescale Classifier-Free Guidance from: https://arxiv.org/pdf/2305.08891.pdf

advanced_model_merging.py

Node for merging models by block.

sdxl_model_merging.py

Node for merging SDXL base models.

reference_only.py

Contains a node that implements the "reference only controlnet". An example workflow can be found in the workflows folder.
