Swapping Lightmaps - UV problems

Hello,

I've searched for an answer for this but not found exactly what I'm looking for. I have a script that loads lightmaps from 2 different folders so that I can switch between night and day. The problem is that the UV mapping for the lightmaps seems to get messed up every time I load from the folders.

The original lightmaps are stored in the scene folder I.e. "Assets/Scenes/Chapel_Test_01/"

I also have night and day versions of the lightmaps stored in the following folders "Assets/Resources/LightmapsNight" and "Assets/Resources/LightmapsDay" respectively.

the script loads the night lightmaps when the "j" key is pressed and loads the day lightmaps when the "k" key is pressed. I.e. once the lightmaps have been changed the first time they are always reading form the resources folder and when I change back to the day lightmaps the UV is still messed up. There are the same amount of lightmaps for day and night so each array should be the same size.

I have attached screenshot showing the problem and also the script in question too. Any suggestions would be greatly appreciated.

thanks

The code below is .js I don't know why it says its C Sharp

Code (csharp):

1.  
2. function Update(){
3.  
4. if (Input.GetKeyDown("j")){
5.     SetLightMapsNight();
6.     }
7.    
8. if (Input.GetKeyDown("k")){
9.     SetLightMapsDay();
10.     }
11. }
12.  
13. function SetLightMapsNight () {
14. var pathString : String = "LightmapsNight/";
15. var lightmaparray : LightmapData[] = LightmapSettings.lightmaps;
16. var mapdata : LightmapData = new LightmapData();
17.     for (var i=0; i<lightmaparray.length; i++)
18.     {    
19.     mapdata.lightmapFar = UnityEngine.Resources.Load(pathString + "LightmapFar-" + i.ToString(), Texture2D) as Texture2D;    
20.     mapdata.lightmapNear = UnityEngine.Resources.Load(pathString + "LightmapNear-" + i.ToString(), Texture2D) as Texture2D;    
21.     lightmaparray[i] = mapdata;
22.     }
23.  
24. LightmapSettings.lightmaps = lightmaparray;
25. }
26.  
27.  
28. function SetLightMapsDay () {
29. var pathString : String = "LightmapsDay/";
30. var lightmaparray : LightmapData[] = LightmapSettings.lightmaps;
31. var mapdata : LightmapData = new LightmapData();
32.     for (var i=0; i<lightmaparray.length; i++)
33.     {    
34.     mapdata.lightmapFar = UnityEngine.Resources.Load(pathString + "LightmapFar-" + i.ToString(), Texture2D) as Texture2D;    
35.     mapdata.lightmapNear = UnityEngine.Resources.Load(pathString + "LightmapNear-" + i.ToString(), Texture2D) as Texture2D;    
36.     lightmaparray[i] = mapdata;
37.     }
38.  
39. LightmapSettings.lightmaps = lightmaparray;
40. }[CODE]

 

I've just noticed it's loading the same light map into each slot so it looks like there's something wrong with the array code?

 

Can anyone suggest why this would load the same map into every slot?

Thanks
