SetConstantTangents works the following way:
- Add SetConstantTangents.cs to the editor
- Impport Animation on prefab
- Resample curves = False
- Anim. Compression = Off
- Hit Apply
- Select all Animation Clips on the Project's Prefab
- Duplicate (Command + D)
- Add the new duplicates on a folder (to keep organized)
- Select them all and go to Tools > SelectConstantTangents
Once the operation is done, the selected Animation scripts should have Constant Tangents
