This is a Category:Legacy Basic Procedure tutorial page. It explains how to perform a single procedure which is required in many different contexts.

This page explains the rebuilding procedure in UnrealEd. See Build for the topic in depth.

Overview[edit]

During rebuilding, UnrealEd examines the actors in the map and recompiles certain data structures. In order, these are:

  1. Geometry
  2. BSP
  3. Lighting
  4. Bot Paths

Rebuilding will also:

Method[edit]

To rebuild all the map's elements, click the Build All button on the toolbar, "build 6" in the screenshot:

On slow computers, it is better to only build the elements you have changed. The remaining build buttons are:

  1. Build Geometry only.
  2. Build Lighting only.
  3. Build Changed Lighting only.
  4. Build Paths only.
  5. Build Changed Paths only.
  6. Build All with the options most recently set in the Build Options Window.
  7. Opens the Build Options Window.

The first three processes are cumulative: rebuilding just geometry + BSP will erase the lighting build. But it's fine to build just the lighting. The paths build is independent.
