I'm attempting to build my own house which has an underground cavern system. The cavern was intended to include holes and exits to the exterior, therefore I decided to use a new world space rather than an interior cell, this is so I'm able to see the sky and have proper lighting effects etc..
So now that you all know my circumstances, could anyone possibly give me any solutions to this problem... When I load the game to test the 'interior' world space, the terrain is suddenly at all different levels. instead of teleporting to the other side of the door, I teleport about 100 meters above the door on a random square piece of terrain, with several other square pieces of terrain at all different heights! so I run to edge of the square and am able to look down on the cavern and see everything!
(if I fall I die) I've used the 'tcl' command to have a look around the cavern which seems to be completely fine, its just the terrain!
I've played about with all the figures in the world space panel... for example, ticking and unticking all the boxes and changing the default heights so that land is higher than water or water is higher than land... and still I have the same sort of problem! Its getting very frustrating!
So I would be very greatful if anyone has a solution or workaround to this problem, Thanks!
