ComfyUI_UltimateSDUpscale

ComfyUI nodes for the Ultimate Stable Diffusion Upscale script by Coyote-A. This is a wrapper for the script used in the A1111 extension.

Installation

Enter the following command from the commandline starting in ComfyUI/custom_nodes/

git clone https://github.com/ssitu/ComfyUI_UltimateSDUpscale --recursive

Usage

Nodes can be found in the node menu under image/upscaling:

NodeDescription
Ultimate SD UpscaleThe primary node that has the most of the inputs as the original extension script.
Ultimate SD Upscale <br>(No Upscale)Same as the primary node, but without the upscale inputs and assumes that the input image is already upscaled. Use this if you already have an upscaled image or just want to do the tiled sampling.
Ultimate SD Upscale <br>(Custom Sample)Same as the primary node, but has additional inputs for a custom sampler and custom sigmas. Both must be provided if one is used. If neither is provided, the widgets (the settings below the input slots) for the sampler and step/denoise settings will be used, like in the base USDU node.

Details about most of the parameters can be found here.
