Efficient Loader

• A combination of common initialization nodes.
• Able to load LoRA and Control Net stacks via its 'lora_stack' and 'cnet_stack' inputs.
• Can cache multiple Checkpoint, VAE, and LoRA models. (cache settings found in config file 'node_settings.json')
• Used by the XY Plot node for many of its plot type dependencies.

Ksampler & Ksampler Adv. (Efficient)

• Modded KSamplers with the ability to live preview generations and/or vae decode images.
• Used for running the XY Plot script. ('sampler_state' = "Script")
• Can be set to re-output their last outputs by force. ('sampler_state' = "Hold")

       

XY Plot

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

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.

       

Examples:

• HiResFix using the Efficient Loader & Ksampler (Efficient)

• 2D Plotting using the XY Plot & Ksampler (Efficient) nodes

• Photobashing using the Image Overlay node

Dependencies

Dependencies are automatically installed during ComfyUI boot up.

Install:

To install, drop the "efficiency-nodes-comfyui" folder into the "...\ComfyUI\ComfyUI\custom_nodes" directory and restart UI.
