Efficiency Nodes for ComfyUI ======= ### A collection of ComfyUI custom nodes to help streamline workflows and reduce total node count. ## [Direct Download Link](https://github.com/LucianoCirino/efficiency-nodes-comfyui/releases/download/v1.92/efficiency-nodes-comfyui-v192.7z) ### Nodes:

Efficient Loader & Eff. Loader SDXL

Can load & cache multiple Checkpoint, VAE, & LoRA type models. (cache settings found in config file 'node_settings.json')
Able to apply LoRA & Control Net stacks via their 'lora_stack' and 'cnet_stack' inputs.
Come with positive and negative prompt text boxes. You can also set the way you want the prompt to be encoded via the 'token_normalization' and 'weight_interpretation' widgets.
These node's also feature a variety of custom menu options as shown below.

note: "🔍 View model info..." requires ComfyUI-Custom-Scripts to be installed to function.
These loaders are used by the XY Plot node for many of its plot type dependencies.

KSampler (Efficient), KSampler Adv. (Efficient), KSampler SDXL (Eff.)

- Modded KSamplers with the ability to live preview generations and/or vae decode images. - Feature a special seed box that allows for a clearer management of seeds. (-1 seed to apply the selected seed behavior) - Can execute a variety of scripts, such as the XY Plot script. To activate the script, simply connect the input connection.

Script Nodes

- A group of node's that are used in conjuction with the Efficient KSamplers to execute a variety of 'pre-wired' actions. - Script nodes can be chained if their input/outputs allow it. Multiple instances of the same Script Node in a chain does nothing.

XY Plot

Node that allows users to specify parameters for the Efficient KSampler's to plot on a grid.

HighRes-Fix

Node that the gives user the ability to upscale KSampler results through variety of different methods.
Comes out of the box with popular Neural Network Latent Upscalers such as Ttl's ComfyUi_NNLatentUpscale and City96's SD-Latent-Upscaler.
Supports ControlNet guided latent upscaling (must have Fannovel's comfyui_controlnet_aux installed to unlock this feature)

Noise Control

This node gives the user the ability to manipulate noise sources in a variety of ways, such as the sampling's RNG source.
The CFG Denoiser noise hijack setting developed by smZ that allows you to closer mimic Automatic1111 style generations.

Note: The CFG Denoiser does not work with a variety of conditioning types such as ControlNet & GLIGEN

Allows you to add noise Seed Variations to your generations.
For trying to replicate Automatic1111 images, this node will help you achieve it. Encode your prompt using "length+mean" token normalization with "A1111" weight interpretation, set the Noise Control Script node's rng_source to "gpu", and turn the CFG Denoiser to true.

Tiled Upscaler

The Tiled Upscaler script attempts to encompas BlenderNeko's ComfyUI_TiledKSampler workflow into 1 node.
Script supports Tiled ControlNet help via the options.
Strongly recommend the 'preview_method' be "vae_decoded_only" when running the script.

AnimateDiff

To unlock the AnimateDiff script it is required you have installed Kosinkadink's ComfyUI-AnimateDiff-Evolved.
The latent batch size when running this script becomes your frame count.

Image Overlay

- Node that allows for flexible image overlaying. Works also with image batches.

SimpleEval Nodes

- A collection of nodes that allows users to write simple Python expressions for a variety of data types using the simpleeval library.
