Every single time, you always have EXACTLY what I need, right when I go looking. Keep up your upload routine my great friend because whatever you are doing is guiding so many individuals down the path of success, each step of the way in real time. I am truly grateful for you and everything you do. Keep at it! Once my game is done, I'd love to provide you with a copy, somehow! Thanks again, for being you 🤘🤘🤘
Perfect timing for this upload, I'm making a Rogue-like for a college project and this is just what I need to generate levels without loading persistent levels and wiping variables thanks a lot man
Matt i had to come to a recent video just to tell you, youre awesome! dude everytime ive needed help and other tutorials failed or just looked crappy, your tutorials always pulled through for me, you do it for free to on youtube, youre a real one matt ive subbed and i continue to like your videos dude, youre a badass, much love man thank you for everything
You mentioned world partition during the video. Would you consider making a video about that too? Would be pretty insightful I reckon considering how useful this one was.
You can also make a variable for Level Load blueprint to make it possible to choose every loading-unloading sublevel through this variable, if it is Isntance Edible
thank you sir! you think you can make an additional video to this about 1- how to have these triggers happen via interaction with a button ? -2- trigger sound and visual effects when the your character overlaps with the boundaries?
God damn, Matt, thank you so much!!! Just what I needed and there aren't really good tutorials on youtube (its either not clear, dont understand or its not what i needed). Most common W from Matt
Can progress from main level go to sublevel and back to main level? For example, collect coins on main level and it shows in sublevel and back to main level.
I was looking for away to combine level streaming with persistent AI for a stealth game. I found the best way was is to keep the AI, the floor and the navmesh in the persistent level and load everything else around them otherwise you have to save there transform and states when u enter and exit a sublevel. Another thing u can though is set all the AI meshs to very low poly base meshs like a low poly version of Manny for instance. then garbage collect the real meshs.
Awesome vid, in depth explanation and honestly now I understand how it works. Thank you! One problem remains, once the player dies in game, should they respawn at last save, I'm not too sure if the level will load should they respawn in the level that only loads when player walks through the box collision, it needs to be written to the save system. How does one achieve this? Is it possible for you to make a video demonstrating how it works please?
Thanks! Instead of creating 2 doors in opposite directions, can we keep just 1 door in the persistent level and use a flipflop in the blueprint to load a level the 1st time and unload the same level the 2nd time?
Matt, can you make a video teaching us how to precompile shaders on packaged games? (like call of duty and apex does) To remove the microstutters that modern unreal engine games often suffer from? Theres little documentation on it that i found and no tutorials about the subject. Thanks!
This looks so good! I was wondering, could you make a tutorial on making a player character automatically follow an AI character? I cannot seem to find anything about this? Would it be AI Move to? etc? The best example that I can think of is when on horse back in Ghost of Tsushima you follow an AI who is leading you to an objective. I would like to use this to drive story telling to my game but I am unsure how to do this? I hope you could either comment here or post a video. I would appreciate your help. Keep up the amazing work.
Hey Matt can you make a video going over how to make speed line VFX with a widget material? The other tutorials on RUclips use Niagara and it’s kinda hacky and not like spiderman 2 or other AAA games
i'M BIT CONFUSED NOW. I thought sublevels was a part of WorldComposition solution= UE4, replaced by WorldPartition system presented in UE5. Should we still use sublevels on top of WorldPartition? I understand WP is for "outside", for worldmap and there sublevels arent needed- world partition grid loading distance does the same work? BUT in indoors levels (dungeons,interiorsa, maybe cities made as a separate level I understand sublevels are still a thing to do?
If you wanted to reference specific blueprint within a level, you will need to do that via its own level blueprint. To access that level blueprint from a different level, you could use event dispatchers. I have a video going over how to use event dispatchers which I’ll link here: ruclips.net/video/Q-QF9bx0m9I/видео.html
Thanks for the video, it's really awesome! I've got one question, if the level I have to load is heavy, is it loading async or the player gets lag spikes and I have to make some sort of optimization?
This is definitely what I was looking for, great work, but I was wondering, if you have multiple sublevels and they are all very much the same size and similar layout, is there a way to load a 'random' one out of the sublevels you have designed, and then when going through that doorway, unloading the previous one you were just in.. By the way, in my case you 'cannot' back track, so your only moving forward through levels, and can no longer go backwards.. I hope that makes sense?
Yoooo Matt, ive got a question maybe only you can answer, im trying to make a level loader das is smooth, (tiny sun over a world, being only what the sun is touching ATM green and everything else gray) but this methois gives more of a chunky feeling not the smoothness we need Any ideas? Thank you for even considerr replying and THANK YOU for your amazing library of knowlade you have build here
As shown at 14:02, you can select the objects you want to move, then right click on the level you want to move them to, and click “move selected actors to level”
Thats amazing, is possible to spawn the same room / level but the walls in the first room move random the generate a different room in the other? Without plaving all walls manually obejct etc?
If you are making an open world game and you wanted to unload the world level would you have to create the world in a sub level or is unloading the world not something that is usually done?
Hello and thank you, I am looking for load/unload based on camera view, is that possible? I mean only load objects are in camera view , if camera for example rotates to other angle, load some objects are in that shot and unload others not in camera view shot. I think that's gonna do super optimization, I need for VR headset. Something Like Ray Cast Thank you.
Is this basically not just World Composition? As in basically what UE5 tried to move away from ?? Very Confused here, I mean I can see why this would be fitting for some edge case games but even than MUCH Confusion...
Can you do a video explaining how to connect to people's projects so you can work in the same levels? It's so horribly done so I hope you could explain it
very cool, I imagine in this system, you would hide this somewhere so people don't see it would there be a way to fade it though ? say that I wanted to go into interior and I wanted to fade outisde world to black ? I don't suppose this is possible , so what I would need to do is to have a combination of sub levels where one gets loaded, one unloaded and I have one common, where I fade visiliby of objecst? very cool video though
Isn't Unreal Engine pushing developers away from Levels/Sub-Levels and towards World Partitioning? Would you still encourage developers to learn about sub-levels instead of spatial loading?
Matt, Can we bake light on these Levels?(for more performance) When I tried it, it didn't worked well and always say that I need to re build light. If you know how to do that please let us know. :) Also, what if it will be co-op game, will it be still good? Like just don't make it load on client?
Also I'm asking if this way help to load to another level not loaded in the same level Example: We have building with the garden and ground floor for services in separate level And full apartment in another separate level with own lights and PPV need to connect them WHEN arrive to elevator it move me automatically to apartment level All by VR .. IS THIS possible in UE5 ??
Hey there Matt, is there something special required to perform a line trace in a sub level? I've been tinkering with a project that wouldn't allow me to line trace when using sub levels and have seen this happen with other is ue5
there must be something i'm missing cause the two actors for load and unload just cancels each other and won't work EDIT: i finally got it fixed it was messing up cause i had another capsule Collison at the front i just had to move them both a bit more far away
i have them both to different levels with the 1st one which unloads front room basically sub 1 i have the 1st actor in front room and the 2nd one being bottom room which is sub 2 which loads front room and unloads bottom room i'll see why that would be
Bro... If you are that far along, why in the flip would you need to wait for someone to make a tutorial. Or is this a case of building the ending before the beginning and middle parts?
Matt I have come to tell you that Jesus Christ loves you, and also that this video is extremely well put together. Very succinct and the opposite of laborious to finish.
Loving the optimization focused vids

That’s amazing to hear, thank you so much for your support!
On thing to note is you don't want to load and unload large levels. You'll get massive drops every time you do it.
You mentioned world partition during the video. Would you consider making a video about that too? Would be pretty insightful I reckon considering how useful this one was.
Simple, easy to follow and understand and exactly what I needed+helped me understand some more aspects of Unreals workflow 👍 Thank you very much
Can you do puzzle and door password and key tutorial in ue4 and how to add vhs tapes so when you pick them up you can play the vhs tape
You can also make a variable for Level Load blueprint to make it possible to choose every loading-unloading sublevel through this variable, if it is Isntance Edible
You've explained everything very well. Thank you! Really useful video!
Thank you so much i was getting so discouraged at the fact that my games were always so glitchy and sluggish
thank you sir!
you think you can make an additional video to this about 1- how to have these triggers happen via interaction with a button ? -2- trigger sound and visual effects when the your character overlaps with the boundaries?

You just actually saved me thank you.
how u know I need this video!!!! nice
Instruction is clear, but the problem would be my own level design skill issue.

What would ue5 be without you, Thank you!! Also would you consider making a tutorial for loading between levels?
This looks so good!

Which is more optimised , oculsion culling or this method , please explain difference
Hello
Thanks for this important tutorial
I'm asking if this way working with VR !?
Thats amazing, is possible to spawn the same room / level but the walls in the first room move random the generate a different room in the other? Without plaving all walls manually obejct etc?
So there's the main/persistent level and then the sub level... Can I have another main level with its own sub levels?
If you are making an open world game and you wanted to unload the world level would you have to create the world in a sub level or is unloading the world not something that is usually done?

Can we replicate it? like make load and unload work separately for players?
Did you happen to find a tutorial on this?
very cool, I imagine in this system, you would hide this somewhere so people don't see it
would there be a way to fade it though ? say that I wanted to go into interior and I wanted to fade outisde world to black ?
