Make terrain flat at runtime
Are there any simple ways to do this? I looked around a lot and couldn't find anything helpful. I'm not very experienced with unity terrain and I need a quick way to make it flat at runtime, through code. Thanks in advance!

using UnityEngine;
public class test : MonoBehaviour {
public Terrain terrain;
int terrainX;
int terrainY;
void Awake(){
terrainX = terrain.terrainData.heightmapWidth;
terrainY = terrain.terrainData.heightmapHeight;
var heights = terrain.terrainData.GetHeights(0, 0, terrainX, terrainY);
for (int x = 0; x < terrainX; x++) {
for (int y = 0; y < terrainY; y++) {
heights[x,y] = 0;
}
}
terrain.terrainData.SetHeights(0, 0, heights);
}
}
A bit late response, but I ran into this problem and ended up here. If you set the terrain's heightmapResolution, the terrain data is lost, i.e. it gets flat. I don't know what it does with its properties, but it gets the job done.
terrain.terrainData.heightMapResolution = yourValue;
Just know that it rounds it to the nearest (correct me if I'm wrong) resolution of (2^n)+1;
