Interest Groups for Culling not working


I must be missing something. The concept of this seems simple enough but it's just not working. I am doing this globally at the beginning of the Photon session ( and during runtime as needed):

//enableSend is just my area, disableSend all other areas

PhotonNetwork.SetSendingEnabled(disableSend.ToArray(), enableSend.ToArray());

//This is for receiving. EnableInterest has my area and close by areas. DisableInterest has all other areas

PhotonNetwork.SetInterestGroups(disableInterest.ToArray(), enableInterest);

I assume I don't have to do anything on the views, once this is set up? Also I am not doing anything on instantiate.

If anyone has any ideas....
