D2 Nodes ComfyUI

[English][日本語][繁体中文]

D2 Nodes ComfyUI is a collection of custom nodes that make ComfyUI slightly more convenient.

It's suitable for those who want to create simple workflows.

I have consolidated the following custom nodes that I previously created, and added nodes such as D2 KSampler.
If you have already installed the following custom nodes, please delete them as the node names will conflict.

• ComfyUI-d2-size-selector
• ComfyUI-d2-steps
• ComfyUI-d2-xyplot-utils

🍅 Nodes

D2 Queue Button

• A button to generate a specified number of images (Batch count)
• Can be moved by dragging the left edge of the palette

Details

• To hide it, configure in the "D2" category of the ComfyUI settings screen
• The number of images can also be specified from the settings screen
• Separate the numbers with commas (,)

D2 Regex Switcher

• Searches input text with regular expressions and outputs matching text
• Can also perform string concatenation

Details

• The main purpose is to switch quality tags for each Checkpoint
• When a matching string is found in the input text, it outputs the target string and which match it was (starting from 0)
• In the image above, it received ioliPonyMixV4.safetensors, matched the search condition pony, so score_9 is output
• Since it matched the first search condition, index outputs 0
• If it doesn't match any conditions, -1 is output
• Can also concatenate strings at the front and back

Input

• text
  • Target string for searching
• prefix
  • String to concatenate at the front
• suffix
  • String to concatenate at the back
• regex_and_output
  • List of search strings and output strings
  • Enter in the following format:
• pre_delim
  • The character inserted between prefix and regex_and_output when connecting them
  • Comma: , / Line break: newline / None: no character inserted
• suf_delim
  • The character inserted between suffix and regex_and_output when connecting them

Search string 1 (regex can be used)
--
Output string 1
--
Search string 2 (regex can be used)
--
Output string 2
--
--
String to output when nothing matches

Output

• combined_text
  • String combining prefix + output string + suffix
• prefix / suffix
  • Pass-through from Input

Usage Example

In this example, the matched number (index) is passed to the Text Index Switch of Easy Use for switching.

Since it becomes -1 when there's no match, we use the regular expression .+ that matches all strings as a default output.

D2 Prompt SR

• A node that searches and replaces input text and returns it as a list
• A custom node for using Prompt S/R with XY Plot
• Compatible with qq-nodes-comfyui

Details

Input

• prompt
  • Prompt. Can include line breaks
• search_txt
  • Text to search for. Can include multiple words
  • Cannot use line breaks
• replace
  • Text for replacement
  • Since it's separated by line breaks, it's OK if it contains ","

Output

• LIST
  • Outputs replaced text in list format

D2 Multi Output

• A node that outputs general parameters like seed and cfg in list format

Details

Input

• type
  • FLOAT: Floating point number. For CFG, etc.
  • INT: Integer. For steps, etc.
  • STRING: String. For sampler, etc.
  • SEED: Can input seed value with random number generation button
• Add Random
  • Adds random numbers to the input field
  • Only displayed when type is SEED

D2 Checkpoint Loader

• A Checkpoint Loader that outputs the full path of the model file

Details

Output

• model / clip / vae
  • Same as the conventional CheckpointLoader.
• ckpt_name / ckpt_hash / ckpt_fullpath
  • Checkpoint name, hash, full path.

The implementation mostly uses code from mikey_nodes.

D2 KSampler / D2 KSampler(Advanced)

• A KSampler that can input prompts as STRING

Details

Input

• model / clip / vae / ..etc
  • Same as standard KSampler
• negative / positive
  • Prompts in STRING format

Output

• IMAGE
  • Image output
• positive / negative
  • Pass-through from Input

D2 Load Image

• Load Image node that can extract prompts from images
• Compatible with images created by StableDiffusion webui A1111 and NovelAI
• A button to open the mask editor has been added

Details

Output

• IMAGE / MASK
  • Image and mask
• width / height
  • Image size
• positive / negative
  • Prompts

Note: Depending on the workflow configuration, it may not always be possible to retrieve prompts. For example, prompts cannot be retrieved without a node containing the word "KSampler" (e.g., Tiled KSampler).

D2 Size Selector

• A node that allows selecting image size from presets

Details

This is an example of obtaining the size from an image, enlarging it by 1.255 times, and then rounding the result.

Input

• images
  • Used to obtain size from images
  • Requires setting preset to custom
• preset
  • Size presets
  • Must be set to custom when using width, height, or images size
  • To change presets, edit /custom_nodes/D2-nodes-ComfyUI/config/sizeselector_config.yaml
• width / height
  • Vertical and horizontal dimensions
  • Requires setting preset to custom
• swap_dimensions
  • Swaps width and height
• upscale_factor
  • Value passed to other resize-related nodes
• prescale_factor
  • Multiplier for resizing width / height
• round_method
  • Round: Rounds to the nearest integer
  • Floor: Rounds down
• batch_size
  • Batch size to set for empty_latent

Output

• width / height
  • Multiplies input width and height by prescale_factor
• upscale_factor / prescale_factor
  • Passes through what was Input
• empty_latent
  • Outputs latent created with specified size and batch size
• batch_size
  • Passes through what was Input

D2 Refiner Steps

• A node that outputs steps for Refiner

Details

Input

• steps
  • Total number of steps
• start
  • Steps where the first KSampler starts
• end
  • Steps where the first KSampler ends

Output

• steps / start / end
  • Pass-through from Input
• refiner_start
  • Steps where the second KSampler starts

D2 Refiner Steps A1111

• A node that can also specify denoise for Refiner in img2img

Details

Input

• steps
  • Total number of steps
• denoise
  • Specifies denoise for img2img
• switch_at
  • At what percentage of total steps to switch to the next KSampler

Output

• steps /
  • Pass-through from Input

• end
  • Ending steps for the first KSampler
• refiner_start
  • Steps where the second KSampler starts

• A node for checking steps

🗂️ Sample Workflow

You can recreate the workflow by dropping the image into ComfyUI.
