A ComfyUI custom nodes package designed to enable multi-regional prompting for architectural rendering, integrated with the Rhino Pseudorandom plugin.

},

“map_semantic”:

[

{

“pmt_txt”: “mid-century modern farmhouse with Shou Sugi Ban siding”,

“pmt_img”: null,

“mask”: “BASE 64 ENCODED BITMAP”,

“pct”: 0.75

},

{

“pmt_txt”: “an text prompt for the object, MAY BE NULL or EMPTY”,

“pmt_img”: “BASE 64 ENCODED BITMAP of a guidence image, MAY BE NULL OR EMPTY”,

“mask”: “BASE 64 ENCODED BITMAP”,

“pct”: 0.00

},

…

],

“img_depth”: “BASE 64 ENCODED IMAGE”,

“img_edge”: “optional BASE 64 ENCODED IMAGE”,

“img_style”: “optional BASE 64 ENCODED IMAGE”,

“pseudorandom_snapshot_version”: 0.1

}

“`

Version 0.4 (Current recommended format):

“`sh

{

“pseudorandom_snapshot_version”: 0.4,

“width”: 1600,

“height”: 900,

“global_guidance”: {

“txt_scene”: “Two-story timber atrium with mezzanine ring and clerestory.”,

“txt_style”: “Soft daylight, neutral white balance, editorial photo.”,

“txt_negative”: “No text, no watermark, no warped structure.”,

“img_style”: “data:image/jpeg;base64,/9j/4AAQSkZJRgABAQ…”

},

“regional_guidance”: [

{

“txt”: “white oak planks, matte finish, tight grain”,

“img”: null,

“mask”: “data:image/png;base64,iVBORw0KGgoAAA…”,

“pct”: 38.2

},

{

“txt”: null,

“img”: “data:image/png;base64,iVBORw0KGgoAAA…”,

“mask”: “data:image/png;base64,iVBORw0KGgoAAA…”,

“pct”: 12.7

}

],

“spatial_guidance”: {

“depth”: “data:image/png;base64,iVBORw0KGgoAAA…”,

“edge”: “data:image/png;base64,iVBORw0KGgoAAA…”

}

}

“`

Note: The PseudoUnpackModelSnapshot node supports both v0.1 and v0.4 formats with automatic detection and backwards compatibility. The v0.4 format provides a cleaner structure with three guidance categories: global_guidance, regional_guidance, and spatial_guidance.

–Manual installation instructions–

IMPORTANT: If you’re using the Windows portable version of ComfyUI, which includes an embedded Python environment, you will first need to install the diffusers module:

1. Install the diffusers library for ComfyUI (Windows Portable Version)

Locate your main ComfyUI_windows_portable directory.

It might be named differently, but this is the main directory where you extracted the ComfyUI portable version. It contains folders like *ComfyUI*, *python_embeded*, and others.

Navigate to the ComfyUI Windows Portable Directory via a Command Prompt:

Open a Command Prompt by pressing Win + R, or typing cmd, and pressing Enter.

Use the cd command to change the current directory to the ComfyUI_windows_portable directory. For example:

“`sh

cd C:\path\to\your\ComfyUI_windows_portable

“`

Install the library using the embedded Python interpreter:

While in the ComfyUI_windows_portable directory, run the following command:

“`sh

.\python_embeded\python.exe -m pip install diffusers

“`

it should look like this:

“`sh

\ComfyUI_windows_portable>.\python_embeded\python.exe -m pip install diffusers

“`

NOT Windows Portable Version:

if you are using your system Python, virtual environment (or Conda environment), run:

“`sh

pip install diffusers

“`

These steps will ensure that the diffusers module is installed within the embedded Python environment used by ComfyUI.

---

2. Install a ControlNet model

There are many places you can download depth ControlNet models, but the one we recommend is diffusion_pytorch_model.safetensors from Hugging Face.

To do this:

1) Download the model:

Download the diffusion_pytorch_model.safetensors file from the link above (https://huggingface.co/lllyasviel/sd-controlnet-depth/tree/main).

2) Move the model to the controlnet folder:

After download is comlpete, move the file to the controlnet subfolder inside the models folder of your ComfyUI directory:

“`sh

C:\path\to\your\ComfyUI_windows_portable\ComfyUI\models\controlnet

“`

OPTIONAL

–Additional Sources for ControlNet Models–

SD-1.5: You can find depth models here: https://huggingface.co/lllyasviel/ControlNet-v1-1/tree/main. Look for files labeled as depth.

SD-XL: Control-Lora models can be found here: https://huggingface.co/stabilityai/control-lora/tree/main.

You can also install models directly from Comfy Manager:

Open Comfy

Go to Manager > Model Manager (Install Models)

Search using keywords like *”controlnet”* or *”depth”* to find and install the desired models

---

3. Install IPAdapter:

Install IPAdapter Plus custom nodes in ComfyUI

Open Comfy

Go to Manager > Custom Nodes Manager (Install Custom Nodes)

Search using the keyword *”ipadapter”*

Click Install on the one called ComfyUI_IPAdapter_plus by cubiq

Install CLIP Vision models

go to https://github.com/cubiq/ComfyUI_IPAdapter_plus?tab=readme-ov-file#installation

follow the instructions for /ComfyUI/models/clip_vision part:

download only the first two CLIP Vision models and rename (the file name gets changed when downloading)

make sure to move CLIP Vision models to ...\models\clip_vision

Install IPAdapter models

navigate to C:\path\to\your\ComfyUI_windows_portable\ComfyUI\models

inside models, create a new folder called ipadapter

go to https://github.com/cubiq/ComfyUI_IPAdapter_plus?tab=readme-ov-file#installation

download the .safetensors files of your choice depending on the preferred SD version

IMPORTANT: We recommend _at least_ downloading:

SD-1.5: ip-adapter-plus_sd15.safetensors, *”Plus model, very strong”* version

SD-XL: ip-adapter-plus_sdxl_vit-h.safetensors, *”SDXL plus model”* version

move the downloaded files to newly created ipadapter folder ...\models\ipadapter

---

4. Make sure you have the SD models (checkpoints)

We recommend:

For SD-1.5: https://civitai.com/models/104608/ai-angel-mix

For SD-XL-1.0: https://civitai.com/models/140737/albedobase-xl

---

5. Last, clone the Pseudorandom repository:

Clone this repo inside your custom_nodes folder by:

Navigate to: C:\path\to\your\ComfyUI_windows_portable\ComfyUI\custom_nodes

Open the folder inside a Command Prompt and type:

“`sh

git clone https://github.com/Pseudotools/Pseudocomfy.git

“`
