ScriptedImporterAttribute.version

Description

Importer version number used by the import layer to detect a new version of the importer.

The import layer uses this version number to trigger re-imports when there is a new version and apply the latest changes made to the scripted importer.

using UnityEngine;
using UnityEditor.AssetImporters;

public class SphereImporter : ScriptedImporter
{
    public override void OnImportAsset(AssetImportContext ctx)
    {
        // ...
    }
}
