function OnPreprocessTexture () : void


Add this function in a subclass to get a notification just before the texture importer is run.

This lets you setup default values for the import settings.

class MyTexturePostprocessor extends AssetPostprocessor
function OnPreprocessTexture () {
// Automatically convert any texture file with "_bumpmap"
// in its file name into a normal map.
if (assetPath.Contains("_bumpmap")) {
var textureImporter : TextureImporter = assetImporter;
textureImporter.convertToNormalmap = true;
