Summary
Engine version: 5.6.1
I’m not sure this is a huge deal because i can fix it but might help with something
The settings enabled in DefaultEngine.ini:
p.Chaos.EnableAsyncInitBody=1
LevelStreaming.AllowIncrementalPreregisterComponents=1
wp.Runtime.UpdateStreaming.EnableAsyncUpdate=true
Updated from 5.5 to 5.6.1
Had PCGs already placed in level. They use world ray hit query then a surface sampler.
Then tried using the new world partition system with previous mentioned cvars.
Hit play and crash
However i deleted the pcgs then the crash stopped. Then placed new ones and the crashing still stopped. So probably not a big deal but might help with something.
Exact assert message:
Assertion failed: QueryParams && TriggeredComponent
File: Engine\Plugins\PCG\Source\PCG\Private\Helpers\PCGWorldQueryHelpers.cpp [Line: 47]
Notes: deleting or disabling PCGs resolves the crash, confirming it’s PCG integration with async preregister.
