1. Install the addon by downloading it from Blender Market and following the instructions provided.
2. Once the addon is installed, open Blender and select the armature object that you want to apply the scale to.
3. Navigate to the Properties panel and select the Armature tab.
4. In the Armature tab, you will see a button labeled “Fix Armature Scale”. Click on this button to apply the armature scale without breaking your animations.
5. Alternatively, you can access the addon by pressing the shortcut CTRL + A, just like you normally do when applying scale.
