Unreal Engine 4 - Related World module

About

This module will allow you to load several maps on server side of you game and replicate its to a one persistent level on a client side, or use it as a offscreen worlds in a standalone game (you need spawn actor with scene capture component for get render from this world)

Installation

• Clone latest sources into Source/RelatedWorld directory of you project
• Edit {ProjectName}{TargetType}.Target.cs file in Source directory and add next code into {ProjectName}{TargetType}Target function

ExtraModuleNames.AddRange(new string[] { "RelatedWorld" });

• Into {ProjectName}.uproject add next code into Modules section

{
  "Name": "RelatedWorld",
  "Type": "Runtime",
  "LoadingPhase": "Default"
}

• Into Config/DefaultEngine.ini add next code into [/Script/Engine.Engine] section

!NetDriverDefinitions=
NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="/Script/RelatedWorld.RwIpNetDriver",DriverClassNameFallback="/Script/RelatedWorld.RwIpNetDriver")
+NetDriverDefinitions=(DefName="DemoNetDriver",DriverClassName="/Script/Engine.DemoNetDriver",DriverClassNameFallback="/Script/Engine.DemoNetDriver")

[/Script/RelatedWorld.RwIpNetDriver]
ReplicationDriverClassName="/Script/RelatedWorld.RwReplicationGraphBase"

• Make sure plugin OnlineSubsystemUtils is on
• Make sure plugin ReplicationGraph is on
• Make sure option EnableMultiplayerWorldOriginRebasing is on
• Recompile you project

Notes

• I strongly not recommend use built in replication graph, due it was added only for experimental purpose.
