Nodes (8)
32 sliders, one per UNet block
The block-merge node that made the SDXL merge era
The SDXL merge node with a terrifying number of sliders
SDXL merge, but you get to weigh each transformer block yourself
Tonemap the noise
Reference-only in one node
The RescaleCFG ancestor that fixes plastic skin and color blowout
Tonemap the noise and rescale the CFG
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.
