terrain setHeights issue

Hi everyone,

I am trying to generate a terrain base on a height map. And I have an issue with the last "column" and last "row" of the map. (see the attached screenshot) some of the heights have a value of 0.

I think I have offsetting every variable possible, hoping it would solve the problem, but for now nothing works ... Does anybody have an idea about what I am doing wrong ?

Code (CSharp):

1.     public void LoadHeightMap(string aFileName, TerrainData aTerrain)
2.     {
3.  
4.         int res = aTerrain.heightmapResolution;
5.         int h = aTerrain.heightmapResolution-1;
6.         int w = aTerrain.heightmapResolution-1;
7.  
8.         Debug.Log(aTerrain.heightmapResolution + ":::::::::::::::::::::::::::::");
9.         float[,] data = new float[w, h];
10.         using (var file = System.IO.File.OpenRead(aFileName))
11.         using (var reader = new System.IO.BinaryReader(file))
12.         {
13.             for (int y = 0; y < h; y++)
14.             {
15.                 for (int x = 0; x < h; x++)
16.                 {
17.  
18.                     float v = (float)reader.ReadUInt16() / 0xFFFF;
19.                     data[y, x] = v;
20.                     //data[y, x] = (float)x / (float)h;
21.  
22.  
23.  
24.                 }
25.                 progress = (float)y / (float)h;
26.                 EditorUtility.DisplayProgressBar("Loading Height Map", "", progress);
27.             }
28.         }
29.         aTerrain.SetHeights(0, 0, data);

 

My first guess would be because you set w and h to one less than resolution. I suppose that you do this because otherwise you're out of range in your data source. Suggest you reduce the height map resolution to that of your data.

 

I don't know anything anymore ... I might have to start from scratch, but I am really afraid to hit the same wall ...
I guess it would be really nice to have builtin function to load Height maps in unity ( i.e the one used in standard terrain script)

 

You need to add one more row and column to your height map data, like this:

float[,] data = new float[w+1, h+1];
