Hi guys, I am proceduraly building a spherized cube based on a number of edges on a corner.
However after all of the building/moving of vertices, my submeshes are flat. I know my function to modify a cube works, however when it is applied to the combined mesh of my generated sides it is invisible. The vertices via the log that they are spherized for World, and the triangle count is correct. Even when I delete the submeshes they appear to be correctly positioned...
I am attaching some code. It's pretty sloppy so far, but it seems fairly simple to understand.

using System.Collections.Generic;

public int smooth = 50; // 0-100 bigger = smoother
Vector3 cubeOrigin;
List vertices;
Transform newSide;
List uvs;
//public Transform newSide = new Transform();
Mesh mesh;
// Use this for initialization
void Start () {
cubeOrigin = transform.position;
//vertices = new Vector3[mesh.vertexCount];
MakeCube();
MakeSphere();
Debug.Log("Loaded");
}
// Update is called once per frame

if (Input.GetKeyDown ("space"))
Debug.Log(mesh.vertexCount);

newSide.parent = World;
newSide.name = ("Side "+(thisSide+1));
//Create Vertices of Side
for (int x = 0;x<=units;x++){
