Level Streaming problems

Please help me! I’m very confused in level streaming. I’m using UE4.4.2, blueprint only(I can use C++ too, but this is easier for me). When I add a level in the Level Window, the level isn’t in the same place as in the tutorials. The screenshots from the tutorials aren’t equal with my screenshots.This is just the first problem…:frowning:
How to use the Level Streaming Volume? First I have to create a new level and design it? Or I just need to drag-and-drop a Level Streaming Volume and create the “new” level in it?
If I get a very useful answer, I will give a very nice gift, after my game is ready. :wink: Anyway Thank you for answering this stupid question!

Hey GSeriousB,

Level Streaming has changed a bit over the last few versions of the engine, so the tutorial you’re following may be outdated. Here’s a basic run-through for 4.4:

The Levels window will start with the Persistent Level. To create a new Streaming Level, click the Levels button in the toolbar for the drop-down menu and select Create New… this will prompt you to save the new Level with a unique name. You can also choose Create New With Selected Actors… this will create a new level and populate it with any Actors you have selected in the Scene.

Then you can create Streaming Volumes that encompass the area of your level that you want to stream. Make sure your Streaming Volumes are in the Persistent Level, and not any sub levels, or they will not work! You can then assign any streaming volumes to levels by opening the Level Details window. With the Level selected (double-click it to make it the current level), click the Level Details button in the Levels window toolbar (it looks like a magnifying glass with a question mark in it). The Streaming Volumes section will allow you to add as many streaming volumes as you want. The drop-down for each volume slot you create will list all volumes you can use. Then you should be good to go!

As a quick setup example, create a new Blueprints Top-Down project. Select the 9 closest boxes in the level, and choose Create New With Selected Actors in the Levels window. Call it LevelOne. Then select the 10 farthest boxes in the level and create a second level named LevelTwo. Your two new Levels will appear in the Levels window. Double-click the Persistent Level in the Levels window to make it current, and then drag two Level Streaming Volumes into your scene. Stretch one out to fit over the area of the closest 9 boxes that compose LevelOne (making sure to increase the height of the volume as well so that the camera will be inside it during play). Stretch the second over the other 10 boxes of LevelTwo. Open the Level Details window for LevelOne and create a new slot for a Streaming Volume, and assign the first volume to it. Do the same for the LevelTwo and the second volume.

Now Play! You should see the blocks appear as you run from LevelOne to LevelTwo, and vice-versa. There are other settings you can play with in the Level Details (including Initially Loaded and Initially Visible, which you might want to set for LevelOne, for example).

Hope that helps! Let me know if you have any trouble or additional questions.

Hey Ben,

Is this a new way of doing this as frequently, this way came up in searches (2mins in) Unreal Engine 4 - Introduction to Level Streaming - YouTube ?

Basically you can right click in the levels list and add it so a selected streaming volume located in the persistent level. Unfortunately I couldn’t get that to work, only the way you described above works for me (through the level details).

Hi elgreeno,

The video you linked to is from March, 2014, at which point we were still in 4.0. I haven’t gone through this video entirely, but I know there were many changes between 4.0 and 4.4 (which I wrote about above). There may be some changes since 4.4, but what I wrote above should still be fairly accurate.

In V5.5 and V4.4 the level details panels doesn’t show any level streaming volume section.(right side of the picture), also the option that says create level form selected actors doesn’t exist. this is a big problem, it something all of us are missing in the set up or is a bug? how come newer versions are worst than older version?,

Hi Daniel,

Do you have World Composition enabled? Level Streaming options do not appear while WC is on.
