Very well explained @MizzoFrizzo - appreciated it. I'm somewhat new to UE and working with a very large level for cinematic flight animation. Was running into resource issues so exploring world partition as a solution and it brought me here. Forgive the newb question but can I apply the beginning portion of your tutorial to a cinematic animation? I don't need the game-based level loading with collision boxes - just to load the portion of my level that will be seen by camera, and not the entire (huge) landscape. Thanks!

Should i use World Partition with data layers or Level Streaming?
@PitchforkAcademy2 ай бұрын
It really depends what you're making, but quite a few devs are opting for levels/sublevels because data layers do have a few issues. For example, as far as I know you can't place instanced foliage into a data layer. If you're trying to make a massive open-world game, I think you'd need to use world partition.

Hi sir, I followed your tutorial and it’s great. I wanted to ask for some more info. When I do the box to load and unload the layer, to unload it’s working great but to load, I need to move the camera so can load the layer fast. If I go straight I can’t see the layer loaded in. I was wondering maybe this can be becouse of bigger group of actors inside the layer to load at once, maybe it’s better to manage it with more sublayers and make the things load up more gradually or it doesn’t metter this ? Thank you and sorry new at this so trying to learn it better possible 🤣

@MizzoFrizzo Hi sir, I was searching for increasing performance in my project. I was wondering if, when I create a data layers levels for example entering in city, making the collision box to activate and disactivate the level, the rest of the landscape can be still seen in the distance trough the gate of the city with HLOD’S created in wp? At least that what is in the viewport 🤣 sorry maybe not so specific question but new on everything so trying to learn 😊 thank you

How would I go about making an open world game in a city? I know this video covers most of the optimizations for stuff like that but what about like for example in Spider-Man when you climb up to the top of the tallest building you can see the entire city from up there. How does the games performance not tank when it has the entire city loaded up at once? Im sure they probably dont load certain props like cars or street lights etc but you still see the entire city and that must still be a lot. How is this done?

What is a good solution to not have a huge FPS drop when loading new data layer? It is quite bad when you have 120 fps and when you are loading in data it drops to 70 for a second or two. I played Aliens fireteam elite and it has terrible stutter when going between loading doors. Or even Dead space remake has the same problem. Is the only solution to make smaller loading chunks and load them with a delay? Because imagine a new playable area a hall and before entering the game tries to load the whole data layer full of high quality assets and it stutters.
@PitchforkAcademy9 ай бұрын
Slow the player down by locking them in an animation, load sections in in chunks, do the loading while the player is paused momentarily in the animation. Very common solution.
@fearfx25627 ай бұрын
It shouldn’t get drops in built project all hard loading will be done at the load of the game and after that it plays with smooth transitions at least that’s how it was with traditional level streaming. Anyway honestly don’t see the net positive using this just yet other than some additional functionality, but don’t think it’s needed unless your doing some really aggressively unperformant game.

@astralstormgamestudios1259 Wherever you want to load something you'd need to funnel the player into that area. One example is if you wanted to have a vast interior environment such as a cave or a city, you wouldn't want the entire interior loaded if your player might just walk by without going inside.

So i've been dealing with the problem for almost a month now. I can't get level streaming on an actor without the player controller. I've used the enable streaming source and streaming source component. However they don't seem to activate. I'm losing my marbles here! I'm starting to think they're just broken! Has anyone tried doing this and run into the same issue? I know one guy on the UE forums ran into something like this. it was that he was running in simulation mode and not pie mode. However I am not. Any help, any word, any thing to get me on the right track would be greatly appreciated it! Thank you! Also Pitch Thanks for the tutorial! It helped alot!
