Terrain isn't supported for mobile. If you're just talking about sheer size as a unit of measure then you'll have to specify the type of game and how your maps will be viewed. Large open maps with mountains and lakes will have to include a lot of matte painting to work on mobile since large map sizes simply won't work. I think (from pure memory) that our terrain sizes are 64x64 - 128x128 and we're probably going to run into a few memory limit problems. The 128x128 map size isn't a problem but filling that space with meaningful assets and gameplay will be an issue.

Logically, terrain support is not implemented for the mobile iOS, as Zach pointed out. Best shot is to use static meshes, not ideal, but you can get a decent amount of detail. Just don't get too complex in terms of size, while developing for an iOS device, memory footprint should always be at the top of your head!

Good luck!

ok, that explains why the iphone simulator crashes when i play my lvl... can i just make a plane based static mesh as my terrain ? or do i have to use bsp? I hope they will implement terrain into the mobile version

Also... how did they make the terrain on the jazz jackrabbit game? is it all bsp?

UDK does not come with an iPhone simulator, are you using the one with the SDK Apple provides or something?

You can use static meshes for terrain. Bust it up into segments, and LOD like crazy.
