- Build changed paths only. This removes all paths from the map, and rebuilds using just the nodes that have been added or changed. This is useful for quickly seeing in the editor if the paths you are working on will work, but because it destroys the entire path network, you can't playtest again until you've done a full path rebuild. It also doesn't generate the automatic path nodes for inventory and pickup items (eg weapons, ammo, health), so these won't appear connected until a full path rebuild.
- Build with the options most recently set in the Build window
- Opens the Build window.
Also note that there are some (hacked) version of UnrealEd with extra buttons.
