Drop this "big box"

#1 By big box do you mean the skybox or do you mean the mission area?
As far as I know there is no way to drop either or.
To make the box look go away all you need to use is a seemless skybox. by the look of it, you are using the same graphic for all sides of your skybox and thats why you are able to see the lines
you can find other skyboxeshere
PS You may want to host your picture somewhere else or compress it more. It took along time for it to load on my computer and i'm at work on multiple t1's

#2 Oh, and if you mean drop it like... lower it, then I don't know. I do know you could raise your terrain though. If that helps.

#3 That's really messed up looking. 0.o

#4 That looks like the order of the skybox images are wrong in the .dml file...

#5 Hi,

Yes u probably havent rotated the top image by 180 degrees. Thats all u need to do - cant remember which way - think its 180 right.... anyway that will sort it
