[bug] AR Object Importer

Hi!
We tried to use AR object tracking with ARkit and found a little bug. When ARkit scan an object and produce xml arobject file it use dots for floats. If I tried to import it by ARObjectImporter from ARkit plugin i received an error.

Code (CSharp):

1. FormatException: Input string was not in a correct format.
2. System.Number.ParseSingle (System.String value, System.Globalization.NumberStyles options, System.Globalization.NumberFormatInfo numfmt) (at <437ba245d8404784b9fbab9b439ac908>:0)
3. System.Single.Parse (System.String s, System.Globalization.NumberStyles style, System.Globalization.NumberFormatInfo info) (at <437ba245d8404784b9fbab9b439ac908>:0)
4. System.Single.Parse (System.String s) (at <437ba245d8404784b9fbab9b439ac908>:0)

11. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

I inspected this problem and I found out that the problem have been appeared beacuse of my default CultureInfo (It is ru-RU). So I wrote a little script to fix it but it is just workaround.

Code (CSharp):

1. using System.Globalization;
2. using System.IO;
3. using UnityEngine;
4. #if UNITY_EDITOR
5. using UnityEditor;
6. #endif
7.  
8. public class FixARObjectImporter : MonoBehaviour
9. {
10. #if UNITY_EDITOR
11.     [InitializeOnLoadMethod]
12.     public static void FixObjectImporter()
13.     {
14.         var file = Directory.GetFiles(Application.dataPath, "*.arobject", SearchOption.AllDirectories);
15.         if (file.Length <= 0) return;
16.         CultureInfo.CurrentCulture = new CultureInfo("en-US");
17.         Debug.LogWarning("WARNING: <color=yellow>CultureInfo was modified to en-US.</color>");
18.     }
19. #endif
20. }
