ComfyUI Extension: ComfyUI_NAIDGenerator

ComfyUI_NAIDGenerator Introduction

ComfyUI_NAIDGenerator is an extension for ComfyUI that allows you to generate images using the NovelAI API. This extension is designed to help AI artists create stunning visuals by leveraging the powerful capabilities of NovelAI's image generation models. Whether you're looking to create new images from text descriptions, modify existing images, or apply unique styles, ComfyUI_NAIDGenerator provides a user-friendly interface to achieve your artistic goals.

How ComfyUI_NAIDGenerator Works

ComfyUI_NAIDGenerator works by integrating with the NovelAI API to generate images based on user inputs. The extension uses a node-based system within ComfyUI, where each node represents a specific function or operation. By connecting these nodes, you can create complex workflows that define how images are generated and processed. For example, you can start with a text description, generate an image, and then apply various modifications such as inpainting or vibe transfer to achieve the desired result.

ComfyUI_NAIDGenerator Features

Txt2img

The Txt2img feature allows you to generate images from text descriptions. Simply connect the GenerateNAID node to the SaveImage node. This will create an image based on the text input you provide.

Img2img

The Img2img feature lets you modify an existing image. Connect the Img2ImgOptionNAID node to the GenerateNAID node and input the original image. The source image will be resized to match the generation size.

Inpainting

Inpainting allows you to edit specific parts of an image. Connect the InpaintingOptionNAID node to the GenerateNAID node and input both the original image and a mask image. The mask image defines the areas to be modified.

Vibe Transfer

Vibe Transfer lets you apply the style of a reference image to your generated image. Connect the VibeTransferOptionNAID node to the GenerateNAID node and input the reference image. You can also relay the Img2ImgOption on it for additional modifications.
