I didn’t know where to post this “bug report” but there is a dead link in the Manual in Advanced > Generating Mesh Geometry Procedurally section.
It’s about the “Example: Creating a Billboard Plane” page
As you can see here :
http://unity3d.com/support/documentation/Manual/Generating%20Mesh%20Geometry%20Procedurally.html
the provided link is
http://unity3d.com/support/documentation/Manual/Example:%20Creating%20a%20Billboard%20Plane.html
but the right one seems to be
http://unity3d.com/support/documentation/Manual/Example_%20Creating%20a%20Billboard%20Plane.html
: have to be replace by _ (or the other way, doesn’t matter to me xD)
