Bug in Triangles method causes overlapping triangles when alpha is less than 1, if sides exceeds 5

[monsieurpooh]

Corrected code:

        List<Vector3Int> Triangles(int sides) {
            List<Vector3Int> tris = new();
            for (int i = 0; i < sides - 2; i++) {
                tris.Add(new Vector3Int(0, i+1, i+2));
            }
            return tris;
        }
