Prop Server / Client replication and distance (Major)

[Nman_Pkr]

Summary

Props that are moved or teleported do not replicate to game clients if the prop is over a certain distance away! This bug is massive and has never been addressed properly. Some times it can be worked around by using a cinematic sequencer device as a parent to the prop in question, but other times it can not! I understand the issue is a result of the optimizations that have been done to UE to make Fortnite BR with 100 players possible. However after Fortnite started adding props that can move I imagine you simply check the actor as always relevant we do not have that ability in UEFN. I would like to point out these two threads that cover the topic in details.

Prop MoveTo() not replicating after a certain distance from camera

So I’m trying to do a topdown camera game where the camera gets further to the player the more they gain in scale. The problem is that it looks like starting from a certain distance, the actor will still show but the movement won’t replicate anymore over the client even though the server seem to still know about it, because the mechanics still work. I’ve tried playing with the “Net Culling Distance Squared” parameter but setting it to 2500000000 (500m I think) won’t change anything… I’m reall…

I have a prop that flies around my island like a blimp. It passes through 4 locations at opposite sides of the island like a giant square path. I noticed at times the prop would get stuck, skip the next location in the path, and then suddenly appear at the next following location after some time. I’ve been using MoveTo in a loop and it absolutely works as intended, never cancels, and always completes. I spent a day debugging this and realized if I move the player closer to the next intended loc…

Pretty sure it’s not an issue they have in BR, it’s just an UEFN constraint

I don’t think I was very clear with my wording in regards to that, It is not an issue in BR because they can just force the props they wish to also replicate to do so. There is an option in UE5 for props to always replicate that we lack in UEFN. Edit: I believe in UE5 under replication section the option is “Always Relevant”.
