Fix issue with LOD0 using lightprobes

instead of assuming there is always a lightmap, just copy the lightprobe usage from LOD0.

 public class LightmappedLOD : MonoBehaviour {
-    //public int LODIndex = 1;

-    // Use this for initialization
     private void Awake()
     {
         currentRenderer = gameObject.GetComponent<MeshRenderer>();
             {
                 try
                 {
-                    renderers[i].lightProbeUsage = UnityEngine.Rendering.LightProbeUsage.Off;
+                    renderers[i].lightProbeUsage = lods[0].renderers[i].lightProbeUsage;
                     renderers[i].lightmapIndex = lods[0].renderers[i].lightmapIndex;
                     renderers[i].lightmapScaleOffset = lods[0].renderers[i].lightmapScaleOffset;
 
             }
