Streaming levels with an offset.

Has there been any progress into looking at why brushes/volumes do not translate with the level transform of instanced streaming levels? I am currently using instanced streaming levels to produce a infinite scroller. This issue is a show stopper since I am targeting mobile and need to use static lighting only. The indirect lighting cache doesn’t move to where the level is streamed in, leaving all movable components in the dark.

Thanks!

Well, static lighting is baked in the editor against current level transform, assuming that transform is final and will not be changed. Same thing with BSP, geometry will be baked with level transform specified in the editor. Changing level transform procedurally during gameplay can be used only with dynamic lighting. Also assuming no BSP in the level, game can not rebuild geometry without editor functionality.

Do you think this could change is the future? I.e rather than rebuilding BSP in a new position, the initially compiled BSP is translated?

I also have problem with no offset of indirect lighting cache. Please help

What is the current state of this problem (for 4.8.2)? If I am settings LevelTransform after creating instance of level streaming and then loading instance of that level, are lighmaps also moving?
I can see, that BSP problem is still valid.

While on the topic, can we get the World Browser to work with dynamically spawned meshes? I would like to set up the streamed levels and then spawn the actors into them during runtime. I think the only thing lacking is the ability to Add Instance targeting specific sub-levels.

I really want this to work and I think this should be looked into more, because I believe that procedural generation is very common among indie developers since it is so efficient.

BP Node For Community, Spawn Multiple Instances of UE4 Level

Dear Everyone,

4.9 Version

I’ve created a BP node for the community to use which has a special solution for ensuring unique instance names to guarantee that multiple instances of level can be spawned.

Thanks Ddvlost for your message, your exemple works pretty well for me.
I would to to go a little further. I need to activate the movement of a streaming level with a key (and a timeline). Nothing happend in my (standalone) game. Do you know why…? As you can see i’m a beginner…

Hey epic, I really like the streaming feature but I was wondering if it’s possible to stream them in at a different position than they are built? The reason I ask is because I want a randomly generated dungeon at run-time. I want to be able create different shaped rooms and then while the player is playing, randomly spawn one.

What I DONT want is to use construct script and randomly generate a dungeon like a maze in unreal editor. This is an awesome feature, but I want to spawn pre-created/lightmapped scenes at a location that I specify.

Please let me know if you need more information.

Cheers,
Oz

Hi, we holp this “LevelController” UE4 Plugin can help you. The “LevelController” UE4 C++ plugin lets you could transform UE4 Levels(Maps) at Runtime in Realtime.

Hi guys! I am a new member of the boards, still reading and learning the basics. I just came across this post and after reading the entire thread, I wanted to thank @ddvlost and every other developer and staff for being so helpful and open with suggestions.

Peace!

Thanks for this info.
I just found that calling ULevelStreamingDynamic::LoadLevelInstance(...) seems to work fine and takes care of most things.
