The alphamap is miss when terrainData is save use CreateAsset

I want get a copy terrainData B of a exist terrainData A.

Code (CSharp):

1.  
2. TerrainData terrainData = new TerrainData();                  
3. // copy terrain data
4. terrainData.RefreshPrototypes();
5. Terrain workTerrain = (Terrain)Terrain.CreateTerrainGameObject(terrainData).GetComponent(typeof(Terrain));
6. workTerrain.Flush();
7.  

The terrain render correctly, but if i save the terrainData B, it's alphamap is miss, don't render correctly.

Code (CSharp):

1. AssetDatabase.CreateAsset(terrainData, newAssetPath);

Why?
Thanks.

 

I call SyncTexture on the terrainData, it report a argumentexception:
ArgumentException: Unrecognized terrain texture name: "SplatAlpha 0"

Code (CSharp):

1.  
2. for (int j = 0; j < terrainData.alphamapTextureCount; j++)
3. {
4.     terrainData.SyncTexture(terrainData.alphamapTextures[j].name);
5. }
6.  

 

You have to use the function with a hardcoded string to indicate you want to sync a splatmap.

Code (CSharp):

1. terrainData.SyncTexture(TerrainData.AlphamapTextureName);

Only have to call this once, it will sync all the splatmaps the terrain contains. You can find the source code reference here: https://github.com/Unity-Technologi...Modules/Terrain/Public/TerrainData.GPUCopy.cs

 

Thanks.
SyncTexture work now, but if i call CreateAsset, the alphamap is still missed.
