About maximum map size limit.

[Xandred]

Hello, i am trying to make a single player open-ended RPG type of map. Since i plan to make the world quite big (480x480), it will most likely go way past 8mb limit. Does this limit only apply to multiplayer maps on Battle.net, or do singleplayer maps have to be hampered by it too?

Nope, the limit is only applicable to multiplayer maps. You can import as much as you want in singles

My single player campaign is currently around 100 MB so you are good to go. Keep in mind, however, that if your computer is slow it can really make using the WE a pain. I'm currently using my old computer while my new one is being fixed and it is soooooooo slowwwwww...

I don't think there are limits. However, I do suggest optimizing the map before you release it (with a backup of course). It helps download speed.

As far as i know the limits only apply for battle.net being 4mb max
and lan (local area network) were it is 8mb max.

No. Both is 8MB for wc3 1.26. In earlier times it was 4MB for both but this was more than 5 years ago.

The limit for single player is somewhere between 2 and 4 GB imo.

But has there been ever a creation that big ? I thought its capping before one GB.

That's a good question. The largest I have come across is APproject's Iceborn and it is only around 183 MB. I'm sure there are larger ones out there but I wonder what the biggest one is. I'm sure it would be something with a large amount of custom music and sounds. They seem to take up a lot of space, as well as high poly models and high quality textures.

2GB is probably the limit as it would then be using the final bit of the underlying 32bit integers which may or may not be interpreted as a sign bit (a negative address).

WoW introduced extended archives which have practically no limit. SC2 uses such archives so SC2 has practically no file limit.

I got curious and crammed a map with music files. Somewhere at 700-900 MB map size wc3 starts crashing when you try to highlight the map in the hosting menu.
There might be ways to prevent the crash but investigating is rather pointless, also as there's always the option of just using the local files.

that is most likely because when you highlight map in warcraft 3 while selecting map, it will load the map into memory, and you most likely allocate too much memory, which causes wc3 to crash(It crashed at around 1.1 GB for me, so it seems about right)

Size is a bitfield maybe?

Only on Windows XP. On Windows Vista and later it should manage at least 2GB before crashing due to insufficient virtual address space.

on the machine I have windows 7 x86, and well I dont know how much physically wc3 allocated, just that task manager was saying something around 1.2 but I think that excludes stuff from page file

I have windows 7x64 it crashes at about 1.2gb on there also. My old vistax64 crashed at about 1.2gb as well.
