Platform Overrides from Editor Scripts

With Unity 3.0, we now have per-platform overrides for some properties such as the texture compression settings (e.g. we can say max size=1024 for iPad but only 512 for Android).

But how can we access this from editor scripts? In scripts, all I see on Texture2D are the properties themselves, like the texture format. How can I set the format to something only for 1 platform from script? I use this to select a bunch of textures and do things like resize them or change their format in 1 shot because doing them 1 at a time literally takes hours.

Use a CustomImportSettings Script

Place this in the Editor folder in Unity

using UnityEngine;
using UnityEditor;
using System;

//Sets our settings for all new Models and Textures upon first import
public class CustomImportSettings : AssetPostprocessor 
{
	public const float globalScaleModifier = 0.0028f;
	
    void OnPreprocessTexture() 
	{
		TextureImporter importer = assetImporter as TextureImporter;
		
		importer.textureFormat = TextureImporterFormat.ARGB32;
		importer.isReadable = true;
		importer.mipmapEnabled = false;

    }
	
	void OnPreprocessModel() 
	{
		ModelImporter importer = assetImporter as ModelImporter;

		importer.globalScale  = globalScaleModifier;
		//importer.globalScale  = 1.0f;
		importer.generateMaterials = ModelImporterGenerateMaterials.None;

    }
}

If you look within the 3.0 Docs at:
file:///Applications/Unity/Unity.app/Contents/Documentation/Documentation/ScriptReference/TextureImporter.html

TextureImporter you will see some PlatformSpecific gets and sets. That should be what you need.
