tough trail
It utilizes both the depth and normal-roughness textures to create outlines with more accuracy than I find in most implementations. I've also implemented some very basic anti-aliasing and experimented with controlling outlines per-material by using the roughness value.
Sampling roughness could be interesting for other uses but as a way to control strength of a screen space effect, works pretty nicely

Very neat. Will you put it on godotshaders?

I'll probably put it in a code repository since it requires setting up a fullscreen quad

See Roughness Affect option.

See `Roughness Affect` option.
How do i use it a enabled it but it just seemed to make the outline smaller

Adjust roughness value in materials.
It is best thought of as a per-material outline alpha

Is there an alternative for Godot 3 ?

You would have to calculate the normals from the depth texture
