How to use ParticleSystem in transition map?

Development Programming & Scripting
1

When travel from map A to map B with commandline “servertravel B”.

I set a actor in transition map with a particle component.

I have set the allow tick before beginplay to true, but ParticleSystem in this actorBP is still not activated.

Some said it’s stuck CPU during transition for some reason.

Is there any way to make it tick in transition cause I want to create a Transition-Map-Game or something else?

I use version 4.26, the transition map level blueprint does not run. Put this particle to transition level, it runs.
