Description

Get overlapping components/actors is not fully populated with initial overlaps by BeginPlay in 4.24, like they were in 4.23

Steps to Reproduce
  • Create a static mesh actor BP, setting the static mesh component's collision profile to overlap all and to generate overlap events.
  • On BeginPlay get overlapping components.
  • Place two of these BPs in the level, initially overlapping one another.
  • PIE/SIE

Result:

In 4.23 each BP detected the other via get overlapping components.

In 4.24 neither BP detects the other.

Note that by setting bGenerateOverlapEventsDuringLevelStreaming for the BPs, the BPs loaded later will detect the ones that were loaded earlier, however their begin/end overlap events are not called, and there is still no good way of detecting these initial overlaps.
