Well, I guess this should really be a FAQ -- just one that we have unfortunately no conclusive answer for (at this time).
Seriously, even though Cafu supports very large terrains already, people often ask how they can make even larger ones, usually for an MMORPG. Maybe the problem is that I don't really know any MMORPG, and have never played one, and thus I'm in a difficult position to provide any help.
As I have no idea how terrain streaming for "endless" worlds is supposed to work (in the client-server context), the best suggestion that I can make is to "work-around" the problem as described here:viewtopic.php?p=3706#p3706
I'm open to any other suggestion as well, but then somebody really had to explain to me in technical terms (or at least in general
technical terms) what changes we principally had to make in order to make Cafu natively support MMORPGs with terrain streaming...
|Is there any possibility to load the "next" map part in any easy way or do I have to write such things by myself?|
Personally, I'd load the "neighbor" map whenever the player walks into a trigger brush that is near the border of the current map, as described in the above mentioned post. This is not a very fancy way to do it, but it works with Cafu as-is, no custom coding required, and well understood and ready to use.
(I also believe that it is a very sound way of doing this. E.g. in "Rage" any many other games they're doing exactly the same, and certainly not because everyone loves loading pauses.)
