Question by TheodoreK98 · Sep 16, 2020 at 08:02 PM · meshverticescombinemeshes

How to combine vertices while removing duplicates AND inheriting connections?

Hello, I'm very new to Unity and C#, and I've been working towards this single task for several days now. I have a map I've taken from pieces of a USGS height-map and converted to a mesh. I've saved both a version with the 28 meshes individually, and one with them together as the same "Mesh" using the "GetComponentsInChildren" method. The problem comes when I try to combine vertices at the edges. I am able to do this but only in a way that moves one edge to another edge, keeping two sets of vertices on top of one another, creating a jagged edge when I apply a material. Is there a way to combine or weld these vertices together without ProBuilder?

Here is my code so far, littered with non functioning attempts as comments.

 using UnityEngine;
 using System.Collections;
 
 
 public class VertComb : MonoBehaviour
 {
 public void CombineVertices(){
 
 Mesh mesh;
 
 Vector3[] vertices; 
 
 
 
 mesh = GetComponent<MeshFilter>().sharedMesh;
 vertices = mesh.vertices;
 //VertexConnection[] connections = new VertexConnection[vertices.Length];
 
 
 for (int i = 0; i < vertices.Length; i++){
    Vector3 curVert = vertices[i]; // get vertex [i]
 
    // compare it to the next vertices:
 
 
      //   var VC1 = connections[i];
      
 
    for (int j = i+1; j < vertices.Length; j++){
      // if any one inside limit distance...
 
           float distancex = Mathf.Abs(curVert.x - vertices[j].x);
           float distancez = Mathf.Abs(curVert.z - vertices[j].z);
      if ((distancex < 0.5f) && (distancez < 0.5f)) {
   //   var VC2 = connections[j];
     // if (VC2 == null)
      //   VC2 = connections[n] = new VertexConnection();
      //   if (VC1== null)
      //   VC1 = connections[i] = new VertexConnection();
      //   VC1.connections.Add(n);
      //   VC2.connections.Add(i);
 
 
        vertices[j] = (curVert); // make it equal to vertex [i]
        
        
        
      }
    }
  }
 
 
 
 mesh.vertices = vertices;
 mesh.RecalculateNormals();
 mesh.RecalculateBounds();
 }
 }
  

Thank you for your help!
