Blendshape Viewer

Any Platform

Blendshape Viewer lets you visualize which area of a model is affected by a blendshape so that you can tweak their values.

Compatibility notes
  • It has been tested to work on Unity 2022, and Unity 6.4, and should work on newer versions.
  • 🌊 No game-specific SDK is required.
  • If you use a version of Unity lower than 2022, you must use version 2.1.2.

How to use​

Choose which object to preview​

Align the scene view with your mesh​

Look around using the Scene tab to focus on your mesh, then press Update to refresh the thumbnails. The thumbnails use the same camera settings as the scene view.

If you want the thumbnails to be larger, change the Thumbnail Size slider, and press the Update button again.

For better results, remember that you can change the field of view of the Scene camera.

Identify which blendshape affects which area​

By default, the thumbnails will display the differences. If you do not want this, uncheck Show differences.

While having your cursor inside the Blendshape Viewer window, press the ALT key to display the original picture without the blendshape applied.

The function of the ALT key can be changed in the dropdown at the top right:

  • To show the original picture when the ALT key is held down, choose ALT shows original.
  • To highlight the differences in yellow when the ALT key is held down, choose ALT shows hotspots.
  • Choose Show hotspots by default to highlight the differences in yellow; holding the ALT key down will show the general area.
  • To disable the function of the ALT key, select ALT does nothing.

Search for blendshapes​

Type on the Search field to filter the results by blendshape name.

You can separate search terms with a space. The search query eye down can find results like eye_lookdown.

The button to the right of the Search field labeled Only show non-zero is a filter that will only show blendshapes that have a value other than zero.

Copy a blendshape name​

Click on the clipboard icon to copy the blendshape name.

Alternatively, you can also select the text that contains the blendshape name.

Change the value of a blendshape​

The slider under each blendshape will modify the value of that blendshape in your scene.

This can also be used while recording an animation.
