What is the absolute minimum you need when creating a whole new map? I want to test something and learn about making maps in the process, but don't want to go through the whole process of making a mod with province info, characters owning what provinces etc. Just want the map to load, everything else be damned.
Also can a map be taller than it is wide? So for instance if Umbrae Spherae is 4096 x 2304, and that seems to be the largest possible so far, can that simply be rotated to 2304 x 4096?
Thanks.
Edit: One more thing, does bit depth matter when saving? Or whether it's saved in 256/24/6 etc?
Edit 2: Ok, since the forum came back to life I managed to finish reading this entire thread, so I can see that the minimum needed is the maps folder, and a map can be taller than it is wide.
I created a very rough map of Britain at the maximum, 2304 x 4096, and it crashed loading the rivers. If I put no rivers on the rivers.bmp it creates an error log 500mbs in size, with the lines
[pdxmapgeneration.cpp:222]: Too small river found at x, x
For every single pixel on the map, it seems.
Whereas if I add even one tiny river it only becomes about 4mbs and has a seemingly random selection of those lines, plus some
[pdxmapgeneration.cpp:559]: Circular river found at x, x
but I've inspected the bmp at close range to be sure, there is nothing at any of those points.
I wondered if it might be size related, so I made a new one at 3072x3072, as that seemed a safe bet, but got exactly the same.
I saw Duinnin had made the Britannia map, so I tried expanding that. I got exactly the same river related errors. I also saw someone had this problem halfway through but I didn't see a resolution to it.
Does anyone know what causes them?
Many thanks.
