Outdoor Navmesh Editing on slower machines[edit | edit source]

If you are having problems editing outdoor navmeshes (crashing, excess memory usage) make sure you're not loading more cells than you need by doing the following.

  1. Open My Documents\My Games\Fallout 3\GECKCustom.ini
  2. Press CTRL + f
  3. enter "ugridstoload" in the textbox without quotes and click find.
  4. change the line to "ugridstoload=1" without quotes
    • Note: Set "ugridstoload=3" when working with navmesh boundaries between cells.

Note: Also, when you're navmeshing, use "N" to hide unloaded navmeshes.
