D2 Nodes ComfyUI

[English][<a href="README_ja.md">日本語</a>][<a href="README_zh.md">繁体中文</a>]

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

:tomato: Nodes

D2 Regex Switcher

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

• 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:

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

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

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

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

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 Size Selector

• A node that allows selecting image size from presets

Input

• preset
  • Size preset
  • To change presets, edit /custom_nodes/D2-nodes-ComfyUI/config/sizeselector_config.yaml
• width / height
  • Width and height dimensions
• swap_dimensions
  • Swaps width and height
• upscale_factor
  • Value to pass to other resize nodes
• prescale_factor
  • Multiplier to resize width / height
• 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

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

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

D2 Refiner Steps Tester

• A node for checking steps
