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

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 🤘🤘🤘

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!

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.

@hunterfilms8115 4 ай бұрын

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.

@BigWormGaming 3 ай бұрын

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?

@zuchmiyoff4734 4 ай бұрын

Great vid! How exactly does unloading work? can I reference actors in an unloaded sublevel from a different sublevel?

@MattAspland 4 ай бұрын

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: kzfaq.info/get/bejne/h5OBeZyT3ZbRaX0.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?

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?

Thank you for the lesson. Please tell me how can I move ready-made objects on the main level to the sub-level?

@MattAspland 4 ай бұрын

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”

@nosalis 3 ай бұрын

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

Which is more optimised , oculsion culling or this method , please explain difference

@thomas_c 4 ай бұрын

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?

@MattAspland 4 ай бұрын

You can definitely do that yes!

@YoutubeAccountMan Ай бұрын

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.

@DeftlyJ 3 ай бұрын

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?

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

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.

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?

IS THIS possible in UE5 ??

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...

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.
