import * as BABYLON from "babylonjs";
import { GridMaterial } from "@babylonjs/materials";
  let size = 10; 
  let grid = BABYLON.MeshBuilder.CreateGround(
    "grid",
    { height: size, width: size },
    mainScene
  );
  let groundMaterial = new GridMaterial("groundMaterial", mainScene);
  grid.material = groundMaterial;
