Low Poly terrains issue

Hi everyone, I’m doing my first steps in Babylon, be indulgent :slight_smile:
I am doing the start of a project where I am generating terrains.
I generate a height map from this website : https://heightmap.skydark.pl/
and then I want this terrain to be as the “render wireframe over mesh” to make the terrain like a low poly texture.
Here is my code : https://playground.babylonjs.com/#N16TE3#3
I saw some tutorials saying that I need to use terrain.convertToUnIndexedMesh() but when I put this line the program doesn’t launch.
Is there any other ways to do what I want ? Am I doing something wrong ?
Thanks by advance
style of what I want to do :

you need to convert when the mesh is ready not before: https://playground.babylonjs.com/#N16TE3#11
