How do i adjust terrain texture sizes via script

1. Click on the Texture asset in your Project folder

2. In the Inspector, make Texture Type "Advanced"

3. Check "Read/Write Enabled"

4. Click "Apply"

5. Repeat this for all your Terrain textures!

6. Write C# Script on your Terrain GameObject:

This example changes all x,y Terrain map tileSizes to 100

 Terrain terrain=GetComponent<Terrain>();
 float newTileSize=100f;

 SplatPrototype[] splats=new SplatPrototype[terrain.terrainData.splatPrototypes.Length];
 for(int i=0;i<terrain.terrainData.splatPrototypes.Length;i++){
     SplatPrototype splat=terrain.terrainData.splatPrototypes[i];
     splats[i] = new SplatPrototype(); 
     splats[i].texture = splat.texture;
     splats[i].tileOffset = splat.tileOffset;
     splats[i].tileSize = new Vector2(newTileSize, newTileSize); 
     splats[i].texture.Apply(true);
 }
 terrain.terrainData.splatPrototypes=splats;

Happy Terrain Coding! =oD
