World Partitioned Navigation Mesh guide - only part of world gets a covered by navdata chunks

[zhenghzzz1]

Hi there,

It’s a Engine bug which causes the ANavigationDataChunkActor’s RootComponent will be destroyed after calling PostEditChangeProperty(). So we always get (0,0,0) when we call GetActorLocation(), and some of the NavigationDataChunkActors will be destroyed for the wrong location.

I post the solution in my other reply:

Why is my world-partitioned NavMesh only being generated partially?

It’s a Engine bug that is already fixed in ue5-main branch on Github. Here is the solution to fix this bug if you build engine from source code: 1./Engine/Source/Editor/UnrealEd/Private/WorldPartition/WorldPartitionNavigationDataBuilder.cpp [image] TObjectPtr compilation fixes ahead of enabling GC barrier 2./Engine/Source/Runtime/Engine/Private/WorldPartition/NavigationData/NavigationDataChunkActor.cpp [image] Fix for ANavigationDataChunkActor having wrong actor location Hope this help…

Hope this helps.
