Raycast not hitting terrain.

your going to need to post more info buddy; why don't you post the code that isn't working right?

Sure, the only code I have is:

     void movementUnit(){
         //Get point
         Ray  ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         this.q = ray;
         RaycastHit[] hits = Physics.RaycastAll (ray.origin, ray.direction, 1000);
         Debug.Log (hits.Length + " " + ray.origin + " " + ray.direction);
         foreach  (RaycastHit hit in hits) {
                         Debug.Log(hit.transform.tag);
             if(hit.transform.tag == "Ground"){
                 processInput(this.transform.position,hit.point);
                     break;
             }
         }
     }
 
     void Update(){
         if(Input.Get$$anonymous$$ouseButtonUp(0) && dfInput$$anonymous$$anager.ControlUnder$$anonymous$$ouse == null){
             movementUnit();
         }
     }
 
     void FixedUpdate(){
 
         Debug.DrawLine(this.q.origin,this.q.direction*1000,Color.yellow);
     }

I am using Arong Granberg path finding and if I create a new empty box and place it under "ground" layer I can hit it with a raycast as well as other object in different layers. The only object I can not hit is the mesh I have for terrain. In addition if I create a new terrain and add same layer/tag specs to it I am able to hit it too. It is very weird to be hones. Anything else I can post that would help ?
