<h2 id="1500-style-single-image-studio-and-prompt-director-for-comfyui">1,500-Style Single Image Studio and Prompt Director for ComfyUI</h2>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.<hr /><h2 id="main-features">Main Features</h2><h3 id="1500-selectable-styles">1,500 Selectable Styles</h3>The included style catalog contains:<ul><li>1,500 unique selectable styles</li><li>12 balanced visual families</li><li>125 styles in every family</li><li>285 retained source styles</li><li>1,215 additional structured style recipes</li></ul>The additional recipes were constructed using curated combinations of visual medium, historical era, rendering method and image treatment.<h3 id="included-style-families">Included Style Families</h3><ul><li>Anime &amp; Manga</li><li>Cartoon &amp; Feature Animation</li><li>Comics &amp; Graphic Novels</li><li>Handcrafted &amp; Stop Motion</li><li>Game, Retro 3D &amp; Stylized Rendering</li><li>Printmaking &amp; Decorative Art</li><li>Horror, Gothic &amp; Noir</li><li>Cinematic &amp; Photographic Illustration</li><li>Fantasy &amp; Concept Illustration</li><li>Painting &amp; Fine Art</li><li>Surreal &amp; Experimental</li><li>General Illustration</li></ul><hr /><h2 id="large-structured-database">Large Structured Database</h2>The package contains 17,509 physically stored JSON records.Major catalogs include:<ul><li>1,500 styles</li><li>73 genres</li><li>1,200 locations</li><li>1,000 narrative events</li><li>1,440 primary actions and locomotion records</li><li>800 secondary gestures</li><li>800 camera, camera-motion and shot records</li><li>240 perspectives</li><li>480 blocking templates</li><li>1,200 protagonists</li><li>800 villains</li><li>1,500 creatures</li><li>400 allies</li><li>400 gods</li><li>400 undead characters</li><li>600 hybrid characters</li><li>400 costumes</li><li>400 props</li><li>400 powers</li><li>300 film worlds</li><li>200 palettes</li><li>200 weather profiles</li><li>200 audio-direction records</li><li>160 story arcs</li></ul>The current Single Image node directly uses the style, family, genre, location, event, action, gesture, camera, perspective and solo-character blocking pools.
