How do I change the compression format of all my texture atlases?
I am trying to change the compression of all my texture atlases to PVRTC_RGBA4 so that I don't have to do them one by one. Here is my code:
if( !file.EndsWith( ".meta" ) )
{
string path = "Assets/Resources/Bundles/" + Path.GetFileName(bundle) + "/Atlases/" + Path.GetFileName(file);
tex2D = (Texture2D)Resources.LoadAssetAtPath( path, typeof(Texture2D) );
PostprocessTexture( tex2D );
}
I get no errors and it pops out what I expect from the last Debug.Log, but it doesn't actually seem to do the compression when I look at the atlas in the inspector. I have also tried using AssetDatabase instead of Resources but that didn't seem to do much of anything.
What am I doing wrong? Or what am I missing?

I figured out my own question. I should have been reimporting the image instead of trying to change the compression on the file. Here is my updated code:
if( file.EndsWith( ".png" ) || file.EndsWith( ".tga" ) )
{
string path = "Assets/Resources/Bundles/" + Path.GetFileName(bundle) + "/Atlases/" + Path.GetFileName(file);
tex2D = (Texture2D)AssetDatabase.LoadAssetAtPath( path, typeof(Texture2D) );
TextureImporter importer = ( TextureImporter ) TextureImporter.GetAtPath ( path );
importer.textureType = TextureImporterType.Advanced;
importer.npotScale = TextureImporterNPOTScale.None;
importer.textureFormat = TextureImporterFormat.PVRTC_RGBA4;
importer.wrapMode = TextureWrapMode.Clamp;
importer.isReadable = true;
importer.mipmapEnabled = false;
importer.maxTextureSize = 4096;
AssetDatabase.ImportAsset( path );
}
This is no longer valid form of update. Most of the properties are obsolete.
