Procedural Mesh not rendering at verticies

im trying to get a mesh plane of 16 segments to render from a point to the mouse position.
i have a debug.drawline that draws a horizontal line from the left hand side of where the mesh should be to the right and it seems to work. However when the mesh renders its completely off where the verticie locatons actually are.

public void DrawBlueprintRoad(float width, Vector3 startPos, Vector3 mousePos)
{
if (startPos != mousePos)
{
Mesh mesh = new Mesh();
mesh.name = "Blueprint_Mesh";
blueprintHolder.GetComponent<MeshFilter>().sharedMesh = mesh;
int segments = 16;
verts = new Vector3[segments * 3];
tris = new int[(segments - 1) * 12];
Vector2[] uvs = new Vector2[segments * 3];
float lengthDifference = Vector3.Distance(startPos, mousePos);
float segmentLength = lengthDifference / segments;
currentNode.transform.LookAt(mousePos);

//Create Verts
for (int i = 0; i < segments; i++)
{
Vector3 drawPoint = Vector3.Lerp(startPos, mousePos, (segmentLength / lengthDifference) * i);
Vector3 vertL = drawPoint + (currentNode.transform.right * (width / 2));
Vector3 vertR = drawPoint - (currentNode.transform.right * (width / 2));
verts[i * 3] = vertL;
verts[i * 3 + 1] = drawPoint;
verts[i * 3 + 2] = vertR;
Debug.DrawLine(vertL, vertR);
float y = i / segments;
uvs = new Vector2(0, y);
uvs[i + 1] = new Vector2(0.5f, y);
uvs[i + 2] = new Vector2(1, y);
}
//Create Triangle
for(int i = 0; i < segments - 1; i++)
{
int tri0 = i * 3;
int tri1 = i * 3 + 1;
int tri2 = i * 3 + 2;
int tri3 = i * 3 + 3;
int tri4 = i * 3 + 4;
int tri5 = i * 3 + 5;

tris[i * 12] = tri2;
tris[i * 12 + 1] = tri5;
tris[i * 12 + 2] = tri1;
tris[i * 12 + 3] = tri5;
tris[i * 12 + 4] = tri4;
tris[i * 12 + 5] = tri1;
tris[i * 12 + 6] = tri4;
tris[i * 12 + 7] = tri3;
tris[i * 12 + 8] = tri0;
tris[i * 12 + 9] = tri4;
tris[i * 12 + 10] = tri1;
tris[i * 12 + 11] = tri0;
}
mesh.vertices = verts;
mesh.triangles = tris;
mesh.uv = uvs;
mesh.Optimize();
}
}

 

If you post a code snippet, ALWAYS USE CODE TAGS:

How to use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

Mesh positions are local, so the Transform on the mesh renderer is applied.

If you use those positions in Debug.DrawRay you need to similarly transform those dots, because DrawRay is world coordinates.

 

thank you for your help. I've removed the blueprint holder from its parent and set it to vector3.zero now the mesh is rendering fine
