Hi, Thank you for both of your help. It seems that PagedLOD is what I need to use to reduce CPU memory usage. I have tried to use PagedLOD briefly before, but I am not clear how I can make PagedLOD unload the unused child nodes once those child nodes are loaded. It seems that my PagedLOD nodes do not remove the nodes once it creates the child nodes. Could you please give me some explanation about the proper way of using it??
Thank you!
