Use rotational symmetry. I can't tell you how to do it because I suck at it, so hopefully Ex will come and enlighten us all. :)
Well the difference between rotational symmetry and x y xy symmetry, is that rotational symmetry creates 4 identical "pieces of pie", whereas x y xy symmetry creates 4 pieces of a square that all mirror each other over both the x and y plane.

To try to give you a visual: in order to create a map with rotational symmetry, the only mirrors are the top left and bottom right sets, all directly tangent corners of the map are not necessarily mirrored. So this means that you create a single piece of your map: a single corner. This corner can be the bottom left, bottom right, top left, or top right. From here you construct the other three identical sides, but they aren't mirrored to the first; they are rotated either clockwise or counter clockwise from the first piece.

Take a look at this image:



This image isn't mirrored over a line of symmetry, however, you can draw a line from the top left to the bottom right and cut this image in half. After that, you can rotate one piece onto the other, and they will be identical.

X Y XY made maps have all four corners mirror each other, while rotational symmetry uses identical (but rotated) patterns.

Note: If the map is two player, you can use rotational symmetry with only 2 "pieces of pie", but if you have four players then you would want 4 identical pieces. The above picture only has 2 "pieces of pie", but it gets the point across of what rotational symmetry is.

Here is a better example of rotational symmetry:



You can see that this picture has no mirrors (unlike the galaxy), but still has rotational symmetry; each third of the picture is identical, and is just rotated 120 degrees from the last third. This is what you would be doing with your map, just with fourths instead of thirds.

So like I said, the only identical parts of a 4 player map with rotational symmetry, would be the diagonal mirrors. You can take advantage of this, and use the xy button to create 2 sides of your map at once.
Thanks for all of that. However, I would need to actually see this because I cant picture things like that in my mind.
I guess its just a matter of waiting for Excal to finish his video(s).

this may sound crazy, bear with me i have just recently started map making, but is it possible to do a symmetrical flip on a diagonal line for example having the top left vs the bottom right? :ermm:

Its all about what symmetry setting you use in SCMD and how you terrain the map. I'm sure it can be done as long as its symmetrical.

Funny that you write that. Someone just told me the exact same thing but about another person in that same forum who is acting pretty dumb. :bleh:

KrayZee shouted: How does one deal with a narcissist who is making things up, exaggerates their statements using words like "worst experience in my life" as to put emphasis in declaring trivial things, can't admit they are wrong and likes to escalate a situation that wasn't even a problem in the first place? I'm already at the point of just straight up ignoring this person and reporting em to forum moderators.

not sure if there's a misunderstanding, because obviously blue posts can be silly as well.
