Test your
map now by selecting "Play from here" by right
clicking the UDK window that you are editing
from.
When you
walk away from the volume it will load the map,
walk off it unloads it. So if you have a map
with lots of meshes level streaming is the best
way to go.
*Please
Note Very important.*
When level
streaming, Kismet commands do not get carried from
level to level. So it is a good idea to have a
main map that has all the Kismet commands and
movers in it. For example, one map should have
all your commands and any kismet driven movers
and the overall terrain or landscape. The other
map or maps should have all
your static meshes, doors that open and close,
vehicles used it that particular area only and
Npc's.
For example. on my terrain or landscape maps, I
would have anything that can always be seen
permanent. Like trees, cliffs or even houses and
structures. But level stream any meshes that are
not always seen.
