Cheesy questions

There are some very random questions that ran across my mind and I couldn’t find any answer or docs for them

  1. What happens when AActor::SetReplicates is called to set replication to false while game is running? does it destroys the simulated instance or just make it locally controlled instance for the time being or it just sits there.

  2. What would happen if I use seamless travel to a map with different game mode than the current one?According to the docs here the game mode persists across seamless travel so what would happen to the game mode set in the map in its world settings?

3.What is the production method for dynamic GI? using LPVs ?

  1. What is Raytraced shadows with Distance fields? is it supposed to remove the strong pitch black dark shadows from a dynamic light source? what about accounting for light bounces?
