Graphics glitch on very large maps

[Laskaris]

I am currently working on a gigantic Earth map with a size of 232 x 112 plots. I notice that, when I use the map in-game, there are some graphics glitches on the right (eastern) side of the map. They only appear from around plot x = 204 or x = 205 onwards. From there, there are some dark horizontal lines running towards the right edge of the map. You can see an example in the screenshot below. The lines appear on the map itself and also on the mini-map.

I have only had this glitch with the gigantic 232 x 112 map, never anywhere else, so I assume it has something to do with the size of the map. Has anyone had the same graphics glitch? Does anyone know if and how it is possible to get rid of it?

I really wonder if a map this size would work...

My map will have 232 x 112 = 25984 tiles. Peope have played with maps even larger than that and made it work. As long as you have a good computer with plenty of RAM, it should be okay.

So, does anyone know the answer to my question?

This happened on some of my huge maps. Since those were made with MapView (I think that's the name, it's a mapmaking utility on these forums), I assumed that was the culprit, but I vaguely recall hearing that this occasionally happens on giant maps, so I'm not sure.

I don't know what causes it, but one thing I've tried is making a small mod that can generate a map of the dimensions I need. That seems to have avoided the issue so far.

Thank you for your reply!

I thought that the Civilization map files are basically text files, so it shouldn't really make a difference which program produces them. Theoretically, you should be able to write one by hand. So I don't think that any particular editor or another is causing this graphics bug.

It might even be something with my specific PC. I haven't yet tried out the map on another PC to try and reproduce the glitch.

I'm not quite clear on your description of how you have avoided he issue. "A small mod that can generate a map of the dimensions I need." What do you mean by that? Modding the new map size into CivIV as one of the basic map sizes?

There is a limit in the DLL that does not allow maps bigger than 256 by 256 tiles. That should not be affecting you though, unless the vanilla DLL has a lower limit?

Also, no matter how good your computer is, if you have maps that are too big you WILL get crashes (MAFs), no two ways about it. It's a function of how the game engine is coded (it's 32 bit and can only use 4GB of memory max), and the only known way around that is Viewports.

Sorry for the late reply.

To answer your question more specifically, yes, it's a mod whose only content is an altered WorldInfos.xml file. I added a new map size that spawns a 80x160 tile map, then use Notepad++ to replace most of the terrain with ocean tiles so I can make the map by hand. It's probably not very efficient or even necessary, but I hate switching between programs constantly when making maps, so I try to keep things within WorldBuilder as much as possible.

Sorry to bring this up again but what is the solution to this problem? Im currently working on an earth map that is 30000 tiles. I get the glitch aswell and was looking for a solution.
