- ---------------------How to Parallax Ceilings and Walls----------------------

- Everyone wonders how the space scenes were created in episode 2 of Duke. This
- is probably the easiest thing to do, and can be used to create all kinds of
- interesting effects. Refer to BIGSKY.MAP and SPACE.MAP to see my meaning.
-
- First, draw out your room in 2d mode. Any type of room will suffice. For now
- though, stick to a large rectangular room.
-
- Second, use lines to draw a sector inside your room. Use ALT-S to make the
- new sector valid. Put the cursor on the lines and make them blocking, if you
- like, but this is not necessary. You should now have a room like so :
-
- ___________________________________
- I _______________________________ I
- I I I I
- I I I I
- I I I I
- I I I I
- I ------------------------------- I
- I_________________________________I
-
- Now, go into 3d mode and pick whatever texture you want for the OUTSIDE sector.
- Don't use Big Orbit in this example. Use the LA texture for simplicity. Once it is in
- place, press P to parallax the texture. Then, move the pointer to the ceiling
- of the outer sector and hold down the left mouse button. Press PgDn, until
- the ceiling in this part touches to floor. Now place the same texture on the
- ceiling and parallax it. All you should have now is a floor and a cityscape.
- The city will look weird, but when you play the level it will look normal.
-
- Space scenes are a little different. Big Orbit has an annoying tendency to
- kill you. Do the same for space, but then make a sector inside the inner
- sector and make it something else, like a room. Make sure the walls block so
- no one can wander out into space and die. This time, parallax the floors as
- well.
-
- IMPORTANT!!!! :
- The only ceiling you have to pull down is the outermost sector. This
- is because if you pull down the other sectors as well, you cannot
- place sprites in space. See SPACE.MAP for example.
-
- Once finished, you can use standard wall masking to put in glass or force
- fields.
-
- Using this method, one could surround an entire level and make it look like
- the level is in space, using windows and such.
-
- Have fun!
