Hi guys, i am learning modding recently. I am a total newbie & i am learning from scratch with the help of MaxEd-tutorial. Right now i am following the MaxED2 basics & i am stuck at Basic Lighting. I have followed each & every step explained in the tutorial but i am stuck in GIS part. When i start the localrender.bat, i get two command prompts- CalculationServer.exe & WinCalculationClient. In Wincal.. prompt i am always getting the "connecting to server..." messeage & in CalculationServer.exe i get Freeclients:ABC-FF6D9CD013A<1746>& Processing Clients: . After that when i again run MaxEd 2.0 & according to the guide select GIS>>Send level, I get "Can't export. There are 1 top level entities that are not grouped to a room." message. So, Kindly provide some help please and plz excuse me for my long post.
