function OnPreprocessModel () : void

Description

Add this function in a subclass to get a notification just before a model (.fbx, .mb file etc.) is being imported.

This lets you control the import settings trough code.

// Disable generation of materials if the file contains
// the @ sign marking it as an animation.

class DisableMaterialGeneration extends AssetPostprocessor {
    function OnPreprocessModel () {
        if (assetPath.Contains("@")) {
            var modelImporter : ModelImporter = assetImporter;
            modelImporter.generateMaterials = 0;
        }
    }
}
