Run-time API

Run-time API for exporting textures from TerrainData can be brought into scope with this using directive:

using AmazingAssets.TerrainTexturesExporter;

Now TerrainData class will have TerrainTexturesExporter() extension with the following methods:

• ExportTerrainLayers

• ExportSplatmapTextures

• HasHoles

• ExportHolesmapTexture

• ExportHeightmapTexture

• ExportHeightmapNormalTexture

• ExportHeightmapNormalTextureWithDetails

• ExportBasemapDiffuseTexture

• ExportBasemapNormalTexture

• ExportBasemapMaskTexture

• ExportBasemapSpecularTexture

• ExportBasemapMetallicTexture

• ExportBasemapSmoothnessTexture

• ExportBasemapOcclusionTexture

• HasPrototypes

• CountPrototypes

• ExportPrototypeDistributionMap

//Example of using TerrainTexturesExporter() extension and its methods

using UnityEngine;

using AmazingAssets.TerrainTexturesExporter;


public class ExampleScript : MonoBehaviour
{
    public TerrainData terrainData;

    void Start()
    {
        //Exporting Splatmaps
        Texture2D[] splatmaps = terrainData.TerrainTexturesExporter().ExportSplatmapTextures();

        //Exporting Heightmap
        Texture2D heightmap = terrainData.TerrainTexturesExporter().ExportHeightmapTexture();

        //Exporting Heightmap Normal
        Texture2D heightmapNormal = terrainData.TerrainTexturesExporter().ExportHeightmapNormalTexture();

        //Exporting Basemap textures with resolution 1024 and split in 4x4 array
        Texture2D[] basemaps = terrainData.TerrainTexturesExporter().ExportBasemapDiffuseTexture(1024, false, 4, 4);

        //Exporting tree objects placement map
        Texture2D[] treePlacement = terrainData.TerrainTexturesExporter().ExportPrototypeDistributionMap(TerrainTexturesExporterEnum.Prototype.Tree, 1024, true);
    }
}

If texture exporter methods are used in the run-time builds, make sure Terrain Textures Exporter shader is inside the Always Included Shaders array of the Graphics Settings
