PSD conversion fails (invalid texture format for texture2d.EncodeToPng()) #5

Closed AurL closed 7 years ago

Unsupported texture format - needs to be ARGB32, RGBA32, RGB24, Alpha8 or one of float formats

Issue with a PSD texture, it seems that the format is not correctly saves here

It's actually due to an update for Unity 5.5(.0f3) where textureFormat is replaced by textureCompression. To fix:

    private void getBytesFromTexture(ref Texture2D texture, out byte[] pixels, IMAGETYPE imageFormat)
    {
        //Make texture readable
        TextureImporter im = AssetImporter.GetAtPath(AssetDatabase.GetAssetPath(texture)) as TextureImporter;
        bool readable = im.isReadable;
        TextureImporterCompression format = im.textureCompression;
        TextureImporterType type = im.textureType;

        if (!readable)
            im.isReadable = true;
        if (type != TextureImporterType.Default)
            im.textureType = TextureImporterType.Default;

        im.textureCompression = TextureImporterCompression.Uncompressed;
        im.SaveAndReimport();

        if (imageFormat == IMAGETYPE.RGBA)
            pixels = texture.EncodeToPNG();
        else
            pixels = texture.EncodeToJPG(imageFormat == IMAGETYPE.NORMAL_MAP ? jpgQualityNormalMap : jpgQuality);

        if (!readable)
            im.isReadable = false;
        if (type != TextureImporterType.Default)
            im.textureType = type;

        im.textureCompression = format;
        im.SaveAndReimport();
    }

Fixed in 1.0.0. Closing
