将Unity工程中图片都转换成crunchedCompression

ImageProcessor.cs

using UnityEditor;

public class ImageProcessor : AssetPostprocessor
{
    private void OnPreprocessTexture()
    {
        var importer = assetImporter as TextureImporter;
        if (null == importer)
        {
            return;
        }

        var needReimport = false;
        if (!importer.crunchedCompression)
        {
            importer.crunchedCompression = true;
            importer.compressionQuality = 100;
            needReimport = true;
        }

        if (importer.textureCompression != TextureImporterCompression.CompressedHQ)
        {
            importer.textureCompression = TextureImporterCompression.CompressedHQ;
            needReimport = true;
        }

        if (needReimport)
        {
            importer.SaveAndReimport();
        }
    }
}
