Curious about how big of a map 4.7.2 can handle?

As the title says, im wondering how big of a map unreal in its current version can support? since when i tried to import my heightmap of 24x24 it kind of… crashes unreal editor :stuck_out_tongue: unless im really dumb and have not set something up right…

P.S learning unreal after learning cryengine is fun

The documentation here is a good place to start, and a similar question was asked here. What size of terrain (in km) are you trying to make?

With the world compositon tool it’s possible to create nearly infinite terrains -> it all depends on the performance :slight_smile:
e.g the new kit open world demo was 256 km2 big

24km x 24km is the size im trying to achieve at the current time

Ah ok, thats cool to know… wonder why my map is crashing the editor then… hmm

Could you probably post your log file (project-saved-logs) + report it on answerhub :wink:

Thats what the crash report is throwing me, ill do the answer hub in a moment

Make sure to post your “real” log file -> project-saved-logs-the file which gets generated after the crash :wink:

Is it the .txt or the .dmp file?

The .txt file :wink:
