Talk:Left 4 dead level creation

L4D Navigation Troubleshooting

Anyone have success in generating a navigable map? I've found that some nav areas are marked as ESCAPE_ROUTE, but it doesn't appear to be persisted to the nav file (or after nav_analyze).

I've marked PLAYER_START and CHECKPOINT areas, but I'm prompted on map load with:

GetGoalArea: Cannot find SPAWN_RESCUE_CLOSET area in FINALE, thus cannot guarantee reachability of goal area 
  Using centroid of finale region...
GetGoalArea: Cannot find end area - no checkpoint or finale located.
ComputeFlowDistances: ERROR - Cannot compute flow.

Any help would be greatly appreciated! --Molaughlen 17:46, 3 Dec 2008 (PST)

I've been adding some notes to the Your First Left 4 Dead Map article that cover some of these questions. It's still a work in progress at the moment, hence why it isn't linked to the main level creation page. There's also some good info over on l4dmaps.net. --brandished 20:43, 3 Dec 2008 (PST)
