The Create Image Generator is where you can generate images with any model of your choice. It is a core node used in most workflows, and can be used in the same way that Layer’s 2D inference form is used. That means you may upload or feed reference images into it, add prompts, use custom trained LoRA models with it, and use its outputs as reference or base images for other nodes.
A 2D generator node’s outputs will always be in a single file format (typically PNG) and a single aspect ratio and resolution. Editing an image into multiple different aspect ratios can be done with the Composition Node, the Prompt Edit node, or by feeding the image into a new 2D Generator node with a different aspect ratio, as a reference image.
Not all 2D models support the same functionality; Some models, like Flux.1 Dev, support pose images, structure images, or other types of reference images. Other models support only normal reference images. We recommend that Workflows users either select a regular Reference Image for their reference images or double-check that the model they are using supports other reference image types when they connect another image as a reference image for the Create Image Generator.
The image below outlines the specific elements of a Create Image Generator:
This field defines the 2D Generation model you would like to use for this generator. Each generator may have a different model, so you may chain multiple generators in a row, each with a different model.
You may either enter a prompt directly into the generator, or you may feed in a prompt node into the generator. Prompts entered directly into the generator cannot be modified when the workflow is run, which can prevent them from being modified when a user runs the workflow.
Similar to the prompt area of the generator, the reference image area allows you to upload a specific image or attach a workflow input into the reference image area.
The aspect ratio and resolution may be defined here. Only a single aspect ratio and resolution may be applied per aspect ratio; If you want to outpaint the image into different resolutions, we recommend following our tutorials to find out how to take a single image and outpaint it with the Composition node and Edit Image node.
You may modify the number of images generated per generator, from 1 to 16. This may greatly increase the number of images and generations nodes further down the workflow.
