Marching Cubes - Triangles not creating
Hi there, I am trying to implement the marching cubes algorithm into a game I am making but ran into a problem. Some of the triangles are not created and/or are squished. What am I missing here? Or what can I do to make this easier in the future? I am using a modified script from Sebastian Lague's video on marching squares, thank you in advance.
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class MeshGenerator : MonoBehaviour {
public SquareGrid squareGrid;
public float size;
List<Vector3> vertices;
List<int> triangles;
public int[,] triTable = new int[256, 16]

Looks to me like you are only drawing one triangle per cube but I cant say for sure, nobody wants to read your whole code. If you could isolate your problem to something more manageable, maybe something could be worked out . If you are not worried about making something yourself, you can go to his GitHub and copy his code.
Edit: I see this was 3 years ago I'm sure you worked it out by now
