So, I found a helpful forum post that suggested adding
DefaultQueryExtent=(X=278,Y=278,Z=250)
to my DefaultEngine-> [/Script/Engine.NavigationSystem]-> SupportedAgents section in order to have pathfinding work correctly.
What exactly is this? I couldn’t find any documentation on it, or explanation as to why it was necessary.
Is there a way for it to be customized in the editor rather than hunting through arcane ini files?
DefaultQueryExtent is the extent used by navigation queries when finding arbitrary FVectors to points on navmesh. It can be set in the editor in ProjectSettings->NavigationSystem->SupportedAgents.
It’s query’s limit, and it’s whatever you set in for your SupportedAgent. This is game specific, but should be at_least typical agent’s radius and half-height. I suggest multiples of that.
