Ground height is used on matrices, not objects, so you can not use ground height when calculating where your characters are to be placed on the level. There should be an option in DeleD to export to .x
You are then able to use LOAD OBJECT "map.x", 1 and position it how you like it with POSITION OBJECT 1, X, Y, Z. For calculating how your characters will walk on it you will need to set up collision via DBC's built-in collision, Sparky's dll, or the Nuclear Glory dll.
