I'm trying to create procedurally generated tiles and I've reached a point where I need to figure out the boundaries of the mesh or the outer vertices of the mesh.

enter image description here

    RaycastHit hit;
    if (Physics.Raycast(bound[ i ].v2, Vector3.forward, out hit)) {
    if (hit.distance > 2) {

I've tried raycasting all the vertices, but still can't get the vertices of the edge. The mesh does have a collider. any help on how i would go about this is appreciated, Thanks.

Have you seen this post about getting the outer/edge vertices from a Mesh? http://answers.unity3d.com/questions/1019436/get-outeredge-vertices-c.html

If your mesh will always be a rectangle you could use the MeshCollider, or more specifically MeshCollider.bounds.extents but that will only return 1/2 the width, length and height, not the vertices.

Depending on what you need to accomplish or the environment you are creating, this may work. If not, let us know what you plan on doing with the data after you get it and that may help clear things up.
