Additive mode versus Subtractive mode
The Unreal Engine 3 is always in Additive mode. There is no real Subtractive mode
like UE2.
Say that with me again... there is no subtractive mode... there is no subtractive
mode.
Choosing Subtractive mode when creating a new map simply inserts a massive 512k x 512k x
512k world-size blue CSG Add cube into the always-additive map. This cube is not
fully optimized, so you will see longer build times if you decide to choose Subtractive
mode.
To optimize the world cube in a Subtractive mode map, simply vertex-edit the massive 512k
world-size blue CSG cube down to slightly larger than the size of your map play area.
You can then select the surfaces of this brush and set their lightmap properties and
Material to a more optimal setting. An optimal Lightmap Resolution value would be
65536, optionally with Accept Lights and Accept Dynamic Lights both unchecked, and an
optimal Material would be EngineMaterials.BlackUnlitMaterial or something similar.
To "change" the current map from Subtractive mode to Additive mode, simply
delete the blue Add cube that is at the outside edges of the world grid.
To "change" the current map from Additive mode to Subtractive mode, simply add a
massive 524288 x 524288 x 524288 blue Add cube, which is the complete world size, then
right-click on the cube brush and choose Order -> To First.
