CLIP Text Encode++ can generate identical embeddings from stable-diffusion-webui for ComfyUI.

This means you can reproduce the same images generated from stable-diffusion-webui on ComfyUI.

Simple prompts generate identical images. More complex prompts with complex attention/emphasis/weighting may generate images with slight differences. In that case, you can try using the Settings node to match outputs.

Comparisons

These images can be dragged into ComfyUI to load their workflows. Each image is done using the Silicon29 (in SD v1.5) checkpoint with 18 steps using the Heun sampler.

Options

NameDescription
parserThe parser to parse prompts into tokens and then transformed (encoded) into embeddings. Taken from SD.Next.
mean_normalizationWhether to take the mean of your prompt weights. It's true by default on stable-diffusion-webui.<br>This is implemented according to how it is in stable-diffusion-webui.
multi_conditioning<blockquote> For each prompt, the list is obtained by splitting the prompt using the AND separator. <br>See: Compositional Visual Generation with Composable Diffusion Models </blockquote> <ul><li>a way to use multiple prompts at once</li><li>supports weights for prompts: a cat :1.2 AND a dog AND a penguin :2.2 (for non-comfy parsers). The weights default to 1</li><li>each prompt gets a cfg value of cfg * weight / N, where N is the number of positive prompts. In stable-diffusion-webui, each prompt gets a cfg value of cfg * weight. To match their behaviour, you can add a weight of :N to every prompt or simply set a cfg value of cfg * N</li></ul>
use_old_emphasis_implementation<blockquote>Use old emphasis implementation. Can be useful to reproduce old seeds.</blockquote>

[!TIP]
You can right click the node to show/hide some of the widgets. E.g. the with_SDXL option.

ParserDescription
comfyThe default way ComfyUI handles everything
comfy++Uses ComfyUI's parser but encodes tokens the way stable-diffusion-webui does, allowing to take the mean as they do.
A1111The default parser used in stable-diffusion-webui
fullSame as A1111 but whitespaces, newlines, and special characters are stripped
compelUses compel
fixed attentionPrompt is untampered with

[!IMPORTANT]
Every parser except comfy uses stable-diffusion-webui's encoding pipeline.

[!WARNING]
LoRA syntax (<lora:name:1.0>) is not suppprted.

Settings

<div align="center"> <img width="1262" alt="Settings-node-showcase" src="https://github.com/shiimizu/ComfyUI_smZNodes/assets/54494639/37b50faa-81f4-41b1-88ec-2b28e9c5708e"> <p>Settings node showcase</p> </div>

The Settings node is a dynamic node functioning similar to the Reroute node and is used to fine-tune results during sampling or tokenization. The inputs can be replaced with another input type even after it's been connected. CLIP inputs only apply settings to CLIP Text Encode++. Settings apply locally based on its links just like nodes that do model patches. I made this node to explore the various settings found in stable-diffusion-webui.

This node can change whenever it is updated, so you may have to recreate it to prevent issues. Settings can be overridden by using another Settings node somewhere past a previous one. Right click the node for the Hide/show all descriptions menu option.

Installation

Three methods are available for installation:

  1. Load via ComfyUI Manager
  2. Clone the repository directly into the extensions directory.
  3. Download the project manually.

Load via ComfyUI Manager

<div align="center"> <img width="1207" alt="ComfyUI Manager" src="https://github.com/shiimizu/ComfyUI_smZNodes/assets/54494639/310d934d-c8db-4c4a-af2a-7a26938eb751"> <p>Install via ComfyUI Manager</p> </div>

Clone Repository

cd path/to/your/ComfyUI/custom_nodes
git clone https://github.com/shiimizu/ComfyUI_smZNodes.git

Download Manually

  1. Download the project archive from here.
  2. Extract the downloaded zip file.
  3. Move the extracted files to path/to/your/ComfyUI/custom_nodes.
  4. Restart ComfyUI

The folder structure should resemble: path/to/your/ComfyUI/custom_nodes/ComfyUI_smZNodes.

Update

To update the extension, update via ComfyUI Manager or pull the latest changes from the repository:

cd path/to/your/ComfyUI/custom_nodes/ComfyUI_smZNodes
git pull
