With this addon you can quickly and easily manage an outline effect on multiple objects in the scene!
The outline effect is widely used in different styles and application fields and is obtained with a combination of modifiers and shaders.
Normally in Blender modifiers and shaders are applied "by object" and even if there are ways to act on multiple objects at the same time it is not always easy or intuitive, the reason for this addon is precisely to simplify life for all artists who use this type of technique, saving them time and effort :-)

Hope you like it!
