1,500-Style Single Image Studio and Prompt Director for ComfyUI

OmniForge Krea2 MegaStyles is a self-contained ComfyUI custom node, structured prompt generator and vertical single-image workflow created for Krea2 Turbo.

It allows you to write a normal image description and automatically combine it with a selected or randomized visual style, subject lock, genre, scene direction, composition, camera language and organized output metadata.

This resource is not a checkpoint and not a LoRA. It is a custom-node package, database and ready-to-use ComfyUI workflow.

Main Features

1,500 Selectable Styles

The included style catalog contains:

• 1,500 unique selectable styles

• 12 balanced visual families

• 125 styles in every family

• 285 retained source styles

• 1,215 additional structured style recipes

The additional recipes were constructed using curated combinations of visual medium, historical era, rendering method and image treatment.

Included Style Families

• Anime & Manga

• Cartoon & Feature Animation

• Comics & Graphic Novels

• Handcrafted & Stop Motion

• Game, Retro 3D & Stylized Rendering

• Printmaking & Decorative Art

• Horror, Gothic & Noir

• Cinematic & Photographic Illustration

• Fantasy & Concept Illustration

• Painting & Fine Art

• Surreal & Experimental

• General Illustration

Large Structured Database

The package contains 17,509 physically stored JSON records.

Major catalogs include:

• 1,500 styles

• 73 genres

• 1,200 locations

• 1,000 narrative events

• 1,440 primary actions and locomotion records

• 800 secondary gestures

• 800 camera, camera-motion and shot records

• 240 perspectives

• 480 blocking templates

• 1,200 protagonists

• 800 villains

• 1,500 creatures

• 400 allies

• 400 gods

• 400 undead characters

• 600 hybrid characters

• 400 costumes

• 400 props

• 400 powers

• 300 film worlds

• 200 palettes

• 200 weather profiles

• 200 audio-direction records

• 160 story arcs

The current Single Image node directly uses the style, family, genre, location, event, action, gesture, camera, perspective and solo-character blocking pools. The remaining structured catalogs are included in the package for legacy functions and future workflow expansion.

Style Selection Modes

Random All Styles

Every style in the complete catalog has an equal chance of being selected.

Balanced Random Families

OmniForge first selects one of the 12 families uniformly and then chooses one style from that family.

This prevents a larger or more common visual category from dominating repeated generations.

Random by Selected Family

Randomizes only within the family selected by the user.

Fixed Style

Uses one exact style selected from the searchable 1,500-style dropdown.

Manual Style Override

A manually entered style takes priority over the dropdown and randomization modes.

Scene Generation Modes

Use Prompt Text

Uses the scene written in the main text editor without adding a database-generated environment.

Fixed Scene

Adds a manually entered scene to the final prompt.

Random Full Scene

Automatically builds a scene using:

• Location

• Narrative event

• Primary action or pose

• Secondary gesture

• Camera direction

• Perspective

• Solo-character blocking

The result remains one standalone image rather than a collage, storyboard or multi-panel layout.

Subject and Style Locks

The node includes separate control levels for:

• Subject identity

• Visual style

Available lock strengths include flexible, strong and absolute modes.

You can use:

• A custom subject description

• A subject name only

• A small built-in profile system for selected known characters

For the most reliable character accuracy, provide a complete custom subject description.

Persistent Anti-Repeat System

OmniForge can remember recently selected database elements and temporarily exclude them from future queues.

Editable repeat windows are available for:

• Styles

• Families

• Locations

• Events

• Actions

• Gestures

• Cameras

• Perspectives

• Blocking templates

The history is stored locally in:

runtime/selection_history_v6.json

Delete this file while ComfyUI is closed to reset the selection history.

Included Workflow

The supplied workflow is configured for a single vertical image at:

1080 × 1920

Default generation settings:

• Eight steps

• CFG 1

• Euler sampler

• Simple scheduler

• Full denoise

• Krea2 Turbo FP8 model

• Qwen3-VL 4B text encoder

• Qwen Image VAE

The workflow also includes:

• rgthree Power LoRA Loader

• Multiple optional LoRA slots

• Automatic positive-prompt transfer

• Dedicated negative prompt

• Dynamic folder and filename generation

• Collision-safe PNG filenames

• Prompt and generation metadata embedded in the PNG

• Read-only resolved-prompt preview inside the OmniForge node

All optional LoRA slots are disabled by default. The referenced LoRA files are examples and are not included in this download.

Required Models

The included workflow expects the following files:

krea2_turbo_fp8_scaled.safetensors

qwen3vl_4b_fp8_scaled.safetensors

qwen_image_vae.safetensors

These model files are not included.

The workflow also uses the Power LoRA Loader from rgthree-comfy. Install rgthree-comfy or replace the LoRA stacker with another compatible model and CLIP loader arrangement.

Installation

1. Close ComfyUI.

2. Extract the ZIP.

3. Copy:

ComfyUI_OmniForge_Krea2_MegaStyles_v6

into:

ComfyUI/custom_nodes/

1. Remove or move older OmniForge installations that contain the same database. Keeping multiple copies may create duplicate nodes and unnecessary scanning.

2. Restart ComfyUI.

3. Refresh the ComfyUI browser page with Ctrl + F5.

4. Load the JSON workflow found inside the included Workflow folder.

5. Verify the Krea2 model, text-encoder and VAE paths.

6. Remove or replace unavailable LoRA names inside the Power LoRA Loader.

No separate pip installation is required specifically for OmniForge.

Recommended Settings

For maximum controlled variety:

• style_mode: Balanced Random Families

• scene_mode: Random Full Scene

• anti_repeat_enabled: true

• style_repeat_window: 50

• family_repeat_window: 4

• scene_repeat_window: 25

• randomize_each_queue: true

For a specific visual result:

• Set style_mode to Fixed Style

• Select the desired style

• Leave manual_style_override empty

• Set style_lock to Strong or Absolute

Filename System

The included robust saver supports dynamic filename tokens such as:

• %subject%

• %style%

• %genre%

• %family%

• %scene%

• %seed%

• %date%

• %time%

• %date:yyyy-MM-dd%

• %date:HHmmss%

Default output structure:

Krea2/OmniForgeMegaStyles/YYYY-MM-DD/subject-style-time.png

Unsafe path characters and parent-directory traversal are filtered before saving.

Existing files are preserved by automatically adding a numerical suffix.

PNG Metadata

Saved images can contain:

• The complete ComfyUI prompt metadata

• The exact prompt generated by OmniForge

• Selected subject

• Selected style

• Selected genre

• Selected scene

• Selection seed

• Filename prefix

• Structured OmniForge generation report

This makes it easier to inspect, archive and reproduce the prompt construction used for an image.

Important Seed Note

The OmniForge selection seed and the KSampler image seed are currently independent.

The OmniForge seed determines randomized database selections and is stored in the generation report. The actual image-generation seed remains controlled by the KSampler.

For exact image reproduction, preserve both the OmniForge settings and the KSampler seed.

Privacy and Local Operation

The supplied custom-node code contains no network-request or telemetry functions.

It operates locally by:

• Reading the included JSON catalogs

• Writing a small anti-repeat history file

• Generating structured text prompts

• Saving PNG files within the ComfyUI output directory
