Note that Godot 3 already features a triplanar option in SpatialMaterial, which can be used to texture triplanar terrain without distortion or having to manually create UV maps. :)
It's not the same.
John shader is
triplanar in one pass for two materials
blending two textures based surface slope.
Godot triplanar is one texture only, there is no blending with a second texture based on slope.
