I do not believe SOE has/will ever release a definitive spec for it, however:
Code:
L 582, -534, -71, 585, -530, -71, 153, 153, 153
P 141, 918, 0, 255, 255, 0, 2, East_Karana
above from Beholder_1.txt
File name seems to be short zone followed by _ and which of the 3 map 'levels' to display it as (using 1 for simplicity) .txt
The file lines are:
L = line (did I need to say that? )
next 3 numbers are start x,y,z of the line
next 3 end x,y,z of the line
last 3 colour of line r,g,b
P = point (location label)
first 3 numbers location x,y,z
next 3 colour r,g,b
next 1 label size
and finally label itself, no spaces, use _ for spaces
One thing to note is that z seem to differ between SEQ and LoY it's common belief that SEQ z's are x10 of LoY, which does seem to work.
