Maximum Map Size

[NightmareGaming]

Hi! Sorry if this has already been asked, but I would like to know if there is a limit on how big a map can be before it starts to slow down. I saw one
thread where there is a 300 MB limit. So would I have to look into streaming technologies to load a map and unload the previous map?

Thanks!

What do you define with map?

map = playable area

or

map = saved level + all packages

How long is a piece of string?

First one

If your referring to rope then that can be endless. The string that holds UniCode can hold up to 1023 characters.

Also by the way I am learning Unreal Script. So far I can type this:

class NightmareGaming extends GameInfo;

event InitGame( string Options, out string Error )
{
`log( "Nightmare, Gaming!" );
}

My point was that there's no real answer to your question. Maximum map size is really more determined by the hardware you're using, and how the map is set up etc.

Alright, well I guess that's the answer, there is no answer >.> Thanks!

Currently I have a Intel Core i5 2500k clocked at 4.3 Ghz, 16 GB Ram, and a GTX 560 ti.

i think there actually IS a fixed size of playable map...like 10km2 or something...
Tried to look for it, but couldn't find it... i read it somewhere on this forum..

He's clearly talking about file size, not physical size.

Lets say he was talking about physical size, would there be a limit? If the limit is 10km2 could you stream in 2 maps to have 20km2?

What I'm asking would it be plausable to have an open world space level?

[ambershee]

There is a limit, although it's pretty big. The limit will be defined based upon the distance from the origin of the persistant level at which floating point math based on coordinates will start becoming inaccurate. You can't get around this by trying to stream anything in because that origin in the persitant level is constant.

Time to mess around to see what I can get

The max level size is something like 35Km^3 it's way bigger than you'd ever really need, with some deception and clever scripting you could do streaming that would make it feel bigger while never actually leaving the bounds of the 35km^3 area.

[ambershee]

Indeed. That kind of space is enormous - even driving a vehicle across it at 60kmph will need over 45 minutes to travel corner to corner in a straight line - that's ignoring the fact that your layout should never allow this, and that you can effectively vertically stack large amounts of content too.
