Hello OLtos
Welcome to the world of the Terrain builder.
There could be a couple of reasons for your problems.
1) Missing required objects ( Towers, maproom etc )
Do what Broes said
Before you compile the map into a .RES file, check the map for bugs using the OBJECTS tab in the right side screen and it will check missing fields, missing map rooms, etc. This usualy fixes Crashes. Also make sure all fields are numbered starting with 1 and don't skip numbers
2) Build Terrain didn't make the .res file properly. ( That's why I exit the program and then run it again before building the terrain.)
Run the Editor again and Build another.
Or you could send the .oba file to me if you want to, at
tscott@accesswave.ca that's if you continue to have problems.
Usually its with this file that the problems occur.
Good Luck
P.S You are not alone, there are lots of people here who will try to help you.
