ControlNet v1.1 a complete guide

ControlNet has changed Stable Diffusion forever. It lets you copy human poses, color, and content of a reference image, to name a few. Mastering ControlNet is a logical next step after mastering prompt building.

Image Browser

  • Extension’s URL:

You have many images. Want to find the older ones? Instead of using File Explorer (Windows) or Finder (Mac), you can view them directly in AUTOMATIC1111 using Image Browser. Plus, you can search for images based on prompts and models.

While very useful, the user interface of the Image Browser extension needs improvement. A new option is Infinite Image Browser.

Canvas Zoom

  • Extension’s URL

Do you find the inpainting canvas too small? Use this extension to easily zoom and adjust the brush size with keyboard shortcuts. It’s great for detailed work on small areas.

Ultimate SD Upscale

The best resolution for Stable Diffusion v1 is 512 pixels on one side. Ultimate SD Upscale allows you to enlarge images with ControlNet and tile by tile. It is helpful if you don’t have a GPU card with a large VRAM.

OpenPose Editor

OpenPose Editor allows you to edit the control image from ControlNet‘s Openpose preprocessor. Now you can adjust the pose precisely when using ControlNet.

Civitai Helper

Extension’s URL:

If you use Stable Diffusion, you probably have downloaded a model from Civitai. But you must ensure putting the checkpoint, LoRA, and textual inversion models in the right folders. Civitai Helper lets you download models from Civitai right in the AUTOMATIC1111 GUI.

As a bonus, the cover image of the models will be downloaded. Use the Scan button to download the model images of existing models.

This Aspect Ratio Selector extension is for you if you are tired of remembering the pixel numbers for various aspect ratios. This simple extension populates the correct image size with a single mouse click.

It is convenient to use these presets to switch between image sizes of SD 1.5 and SDXL.SD1:1, 512, 512 # 1:1 square SD3:2, 768, 512 # 3:2 landscape XL1:1, 1024, 1024 XL5:4, 1152, 896 XL3:2, 1216, 832 XL16:9, 1344, 768 XL21:9, 1536, 640
