By the way a map 100km x 100km equals 10,000 sq/km which would take appx. 2314 days or 6.3 years to create. So much for that idea.

The above script I wrote will NOT be rendered on this stupid FORUM properly. This website sux! Be sure to insert 2 spaces before the commands in the Loop.

7- Minimize Minecraft and run the .ahk file with Autohotkey. Autohotkey is now running and you have 60 seconds before he moves. Bring Minecraft back up, UNPLUG your USB mouse, and wait for your guy to move in 60 seconds. So be VERY sure he is positioned correctly before he starts moving. Once this starts, you can NOT change the direction he is facing or you are waisting your time.

8- Watch the flying progress to see if hes flying properly. Now turn off your monitor and walk away from it. Don't touch it. Don't mess with it. LEAVE IT ALONE! Come back in a few days to check on the progress. The only key you should touch is 'F3' to check the location.

9- Once the map is the size you want, Plug your USB mouse back in. Bring up Task Manager and select AutoHotkey.exe and End Process. That will stop the program.

10- This process will render a map completely and thoroughly.

5- Copy and paste the above script to a notepad text document and save it as an .ahk file. Like this ...
MappingMacroMC.ahk

6- Start Minecraft with your map set-up with the appropriate seed and in creative mode. Fly your guy to ...
x:0
y:135
z:0
and point him north. This puts him in the center of the map and at a high altitude so that he doesn't hit anything.

Tt1 = 1000
Sleep 60000
Loop 1000
{
Send {w down}
Sleep Tt1 := Tt1 + 7000
Send {w up}
Sleep 1000
Send {a down}
Sleep Tt1 := Tt1 + 7000
Send {a up}
Sleep 1000
Send {s down}
Sleep Tt1 := Tt1 + 7000
Send {s up}
Sleep 1000
Send {d down}
Sleep Tt1 := Tt1 + 7000
Send {d up}
Sleep 1000
}

3- Download the 'Autohotkey' macro program that is appropriate for your operating system and install it.

4- Run this simple script I wrote for it. It's based on 'time' and 'movement' of your character. NOT 'location' of your character.

Well I figured out how to make a fully rendered map. But first there are a few things I have got to get off my chest.
1- MC Terra is useless.
2- Minetography is crap.
3- Java is f^(%!#g garbage.
4- MC Edit is only useful after you get the map made.
5- Any other hack program I haven't mentioned simply can NOT do the job. I don't care what you think.

*** This is what you need to have to do it. ***

1- An 'excellent' running computer that can handle client Minecraft in single player creative mode. With minimal lag and no crashing problems.

2- This must be a 'spare' computer that will not be used or touched for at least 3-5 days for a good size map.
6 hrs = 26 sq/km
12 hrs = 52 sq/km
1 day = 104 sq/km
2 days = 207 sq/km
3 days = 311 sq/km
4 days = 415 sq/km
5 days = 519 sq/km
(appx. 4.3214 sq/km per hour)

I found a way to create massive maps but I'm having trouble posting it here. I will post it piece by piece, bare with me...
