WLSH ComfyUI Nodes
A set of custom nodes for ComfyUI created for personal use to solve minor annoyances or implement various features.
Node descriptions
Checkpoint Loader with Name
The regular checkpoint loader with an output that provides the name of the loaded model as a string for use in saving filenames
KSamplerAdvanced (WLSH)
Modified version of the advanced KSampler to return the denoising option for experimentation
Seed to Number
Converts a SEED type to an INT, which was needed for some third party nodes
Seed and Int
Generates a seed and outputs as an INT and SEED type to allow the number to be used with nodes looking for varying inputs
SDXL Steps
A single node that outputs three different integers for use as step count in SDXL workflows.
SDX Resolutions
Outputs height and width integers from a list of SDXL optimal resoultions
Multiple Integer
Simple math node to multiple an integer by an integer.
Time String
Returns a formatted string of the current time in the selected format. Useful for filenames or debugging
Empty Latent by Ratio
Quickly generate an empty latent by selecting an aspect ratio, an orientation (landscape or portrait) and the length of the 'shorter' side
Resolutions by Ratio
Similar to Empty Latent by Ratio, but returns integer width and height for use with other nodes.
SDXL Quick Empty Latent
Quickly generate an empty latent of a size from a list of ideal SDXL image sizes
CLIP Positive-Negative
Simple CLIP box containing positive and negative prompt boxes. Mostly a space saver
Clip Postive-Negative w/Text
Same as the above, but with two output ndoes to provide the positive and negative inputs to other nodes
Outpaint to Image
Extends an image in a selected direction by a number of pixels and outputs the expanded image and a mask of the outpainted region with some blurred border padding.
Generate Edge Mask
Used to generate a 'stripe' of mask with blurred edges that overlaps an original iamge with the outpainted new space. Use on a second pass of an image to 'redo' the masked stripe region and help smooth out the edges of an outpainted image. Pass output to a Convert Image to Mask node using the green channel.
VAE Encode for Inpaint Padding
A combined node that takes an image and mask and encodes for the sampler. Can apply some padding/blur to improve inpainting behavior.
Image Scale by Factor
Scale an image by a predefined factor without a model
Upscale by Factor with Model
Does what it says on the tin. Scales using an upscale model, but lets you define the multiplier factor rather than take from the model.
SDXL Quick Image Scale
Take an input image and do a quick simple scale (or scale & crop) to one of the ideal SDXL resolutions
Image Save with Prompt Data
Save an image with prompt information embedded as a comment or exif data similar to how Auto1111 does it. Need to feed it various pieces of information and then specify the filename syntax for replacement if desired. Filename ptions include %time for timestamp, %model for model name (via input node or text box), %seed for the seed (via input node), and %counter for the integer counter (via primative node with 'increment' option ideally). Writes the above as well as positive and negative prompts (convert their widgets to inputs to connect to a prompt string box for easy automation). As far as I can tell, does not remove the ComfyUI 'embed workflow' feature.
Save Prompt Info
As the above, but to a txt file
Image Save with Prompt File
Combination of the above two
Save Positive Prompt File
Saves just the connected text info (expected to be the positive prompt) to help with training. Make sure to do matching filenames!
Build Filename String
Takes inputs similar to the Image Save node, used to build a filename which can be passed to multiple other nodes
Disabled or Non-Functional Nodes
Alternating KSampler
Work in progress. Attempting to recreate the alternating prompts of Auto1111. Provide a prompt with the syntax "<foo|bar>" for it to alternate between "foo" and "bar" (and any number of others) before looping back around to the first entry. Currently not functional due to sampling issues, but the prompt alternating logic works.
Generate Face Mask
Use a face detection library to create a mask box on a desired color channel to then be passed to the Convert Image to Mask node, but currently not working.
Example Workflow
Here's an example hi-res workflow using various WLSH nodes.
