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.
