Openpose Controlnets (V1.1): Using poses and generating new ones

Openpose Controlnets (V1.1): Using poses and generating new ones

What are Controlnets?

Think of control nets like the guide strings on a puppet; they help decide where the puppet (or data) should move. There are several controlnets available for stable diffusion, but this guide is only focusing on the "openpose" control net.

Which Openpose model should I use?

TLDR: Use control_v11p_sd15_openpose.safetensors

This guide covers the control_v11p_sd15_openpose.safetensors model. There are other openpose models floating around such as:

  • control_sd15_openpose.safetensors

  • controlnetPreTrained_openposeV10.safetensors

  • t2iadapter_openpose-fp16.safetensors

Any of these except the t2iadapter_openpose-fp16.safetensors models work similarly, if not identically. I was not able to get poses out of t2iadapter_openpose-fp16.safetensors at all.

Identical results from control_openpose-fp16, control_sd15_openpose, and controlnetPreTrained_openposeV10.


  1. Install the v1.1 controlnet extension here under the "extensions" tab -> install from URL

  2. Download the control_v11p_sd15_openpose.pth and control_v11p_sd15_openpose.yaml files here.

  3. place the files in stable-diffusion-webui\models\ControlNet

  4. Reload the UI. After reloading, you should see a section for "controlnets" with control_v11p_sd15_openpose as an option

  5. Download some poses on Civitai or make your own (later in this guide).

Using Openpose with txt2Img

  1. Enter prompt and negative prompt

  2. Select sampler and number of steps

  3. Drag the black wireframe into the ControlNet field

  4. Controlnet settings:

    • Enable: Checked

    • Pixel Perfect: Checked (or same aspect ratio is OK)

    • Preprocessor: None

    • Model: control_v11p_sd15_openpose.pth

    • Weight: 1*

    • Rest of settings default

      *setting the weight to less than 1 may capture the pose in a more general manner. See the generation grid below for comparision

  5. Generate!

    • Troubleshooting:

      • Enable is checked?

      • Preprocessor is none?

      • Deleted openpose v1.0 extension and models?

        • using control_v11p_sd15_openpose?

How does this work?

The openpose model with the controlnet diffuses the image over the colored "limbs" in the pose graph. This allows you to use more of your prompt tokens on other aspects of the image, generating a more interesting final image.

Changing the weight will continue to apply the pose in a more generalized way until the weight is too low. In the example above, between 0.4.-0.2 weight was too low to apply the pose effectively.

Generate new poses

There is a great extension which allows you to generate an openpose from an existing image. You can also use it to create poses from scratch, or edit poses generated from an image.

  1. Install the openpose editor under the "extensions" tab -> install from URL


  2. Reload the UI.

  3. Go to the "3d Openpose" Tab

  4. Detect from image

  1. Browse for the image or drop it on the "browse..." button

  1. Set canvas width/height to the same as the input photo (same aspect ratio is OK).

  2. If the preview looks good, click "Generate Skeleton/Depth/Normal/Canny Map"

  3. For the skeleton set the ControlNet number to 0. For every other output set the ControlNet number to -.

  4. Expand the "openpose" box in txt2img (in order to receive new pose from extension)

  5. Click "send to txt2img"

    • optionally, download and save the generated pose at this step

  6. Your newly generated pose is loaded into the ControlNet!

    • remember to Enable and select the openpose model and change canvas size

    Final result:
