[@Anthrocarbon]

First of all your typing speed and accuracy sounds like a stampede of little keyboard construction workers and I love it! Secondly, thanks for another great source of information about Unity features that are somewhat buried behind a competence barrier. I refer constantly to the official unity script API page and would never have found this info considering the way I browse it. I've been looking for a mechanism to increase performance on a single-scene game I'm building with a huge number of unique one-off meshes and materials, and I think this will be key to the solution. Thirdly, I continue to find it amazing how your videos make me feel smart and also stupid at the same time! This is great for helping me get an objective sense of my capabilities as a game dev, and I appreciate the opportunity to see how pro-level development is approached. Once again, the Unity community has shown that it follows an unspoken credo of helpfulness, unlike many other programming niches where the professionals and wizards treat the newcomers like worthless scum. CM, you make me feel included and respected.

That's great to hear! I'm glad the video helped you! Thanks!

[@N1ghtR1der666]

I would love to see how you break up a 3d continuous world with subscenes and also once your world gets bigenough how the editor window performance is effected and can be improved. Another aspect with 3d worlds would be how do you deal with distant but visable objects that are visible from multiple subscenes away (consider a tower in or mountain in the distance)

[@00xenobil00]

Its the same thing, but you render everything in in a line in front of the character and dont render anything in the back and sides of the character.

[@S_Tadz]

@@00xenobil00 culling and dynamically loading map chunks are not the same thing. You definitely can use both

[@therealpeter2267]

You could use multiple LOD levels of subscenes, so like layer bigger subscenes, holding towers and big things, and smaller subscenes, holding trees, then grass, etc...

[@JiraMelaj]

Also helpful would be how to build a full size spherical (or geodesic polyhedra) planet without crashing the editor. There is a bit of a catch 22 with needing it cut up before making it. Looks like it would need to be done in stages with math & not just plopped in...

[@JiraMelaj]

Basically, some in editor dots terrain generation. Probably need to start as base shape before transformed into stuff & it's LODs.

Thanks always for your great work and ispiration. I reimplemented your example using Unity 2022.3 with Entity 1.0 and compare with MonoBehavior SceneManager.LoadSceneAsync. I create a demo Scene with 10000 SpriteRenderers. ECS -> SceneSystem.LoadSceneAsync has a very huge peak (FPS drop) at the really begin and it takes 37 frames to load the Subscene Mono -> SceneManager.LoadSceneAsync does not have any huge peak at the start and it takes 21 frames to load the scene (LoadSceneMode.Additive) During scene async loading they both have a similar fps It would be interesting if you create similar tests, to compare these two worlds (Mono and ECS). I guess with your experience you can create more reliable test results than mine.

[@brockormond4131]

As a theoretical, can you still have interactions in unloaded subscenes? Say you have a NPC chopping a tree down in an unloaded scene, can it make a sound? ;P But seriously, if there is a dynamic system in an unloaded subscence, can you still have its effects spill into loaded scenes? (Ex. A dam is set to blow on a timer and flood a region, but no one is around to see it, can other regions down river get flooded anyway?)

[@washynator]

I'm an idiot, so you should probably wait for a comment from someone who knows anything. But I would imagine that it wouldn't be possible to have stuff happen in unloaded scenes (they are unloaded, after all). My (stupid) solution would be to use some kind of a trigger to make the thing happen anyway (you can use whatever system to load the scene to make the flood happen). For example game time? As in "after the game has been going for 50minutes, load the scene with the dam and destroy the town, then unload the scene until the player comes near".

[@brockormond4131]

@@washynator That's certainly one way for that sort of thing; but I'm thinking about dealing with massive dynamic environments where things can happen even without player involvement. Maybe something like another 'subscene layer' like how there can be a 'low render' and 'high render' scene depending on distance; there could be a 'data layer' which needs what's in the environment, but not any of the visual components (meshs/partical effects). Really just thoughts that came to me while watching the video.

[@CodeMonkeyUnity]

Unloaded Subscenes don't really exist, if you look in the Entity Debugger the entities don't exist. I'm not sure if you can modify SubScenes after they've been converted, I believe they are meant more for the static parts of your game, so in your case you could use it for the terrain and whatever trees and rocks that never move but the dam and the water would be in normal entities on in a subcene that is never unloaded.

[@zaingill9527]

@@CodeMonkeyUnity So anything that is unloaded as a part of the subscene can't hold any state or persist and do it's own thing due to it not existing makes sense

[@martimking1craft]

You should do what terraria does to subscenesyou have a timer always running and when a subscene is loaded it grabs your timer and do some time checks to decide what is the current state of the sub scene

[@foomaster6353]

New to Unity, have been watching you videos and they have really helped me out a lot, thank you! Quick but possibly stupid question, would using prefabs in subscenes still propagate changes like they do if they weren't in a subscene? For example, if you wanted to change the color of the grass would you just change the prefab or would you have to "unpack" all the subscenes, change the prefab, then "repack" them?

[@gdb5549]

does this work for 3d too?

[@BarioIDL]

can i use subscenes for each characters like the layers of subscenes you mentioned?

[@GunslingerP]

How would you create subscenes to make procedurally generated content? it seems you have to have a subscene created before you start a game, but there is no way to duplicate scenes. So there's really not a way to use this to make infinite worlds...

[@erikm9768]

If changes are made to a subscene in run-time, are these changes persisted if you unload and load again?

[@Un4GivNX]

[@laserbean00001]

So this is only for a static environment right?

[@andrewshandle]

This is a great video and I can't wait to give it a try. One thing I've noticed on this and the Prefab video is you are making Systems instead of Jobs for some of these systems. While I haven't tried this particular one out yet, shouldn't a "SceneJob" work fine to handle all of this or would it not worth with the Burst Compiler? Similarly I've found that spawning a prefab in a Job with DOTS also doesn't work with the Burst Compiler which is frustrating, if I want a Player to fire a Projectile Entity (something that would be incredibly common in a game), not being able to do that in a worker thread seems to be a problem. That, or am I missing something? (I really hope I am).

[@iCeDrAgOn2025]

Not every system has to contain a job. Systems such as movement or turning on or off a single entity would run so quickly that it's actually better not to set such up as a job because it would just lead to you as the developer needing to write more code.

[@andrewshandle]

@@iCeDrAgOn2025 The new JobComponentSystem in the latest preview is the same amount of code as a ComponentSystem and it'll use Burst Compile by default. You'd think for consistency you'd just use the same one all the time if possible. I do think Systems are a bit easier by default since it doesn't require using Buffers, but it'd be nice for the future of DOTS if there'd be a consistent way to do it.

[@MechabitGames]

@@andrewshandle I think creating a job has an overhead so for player interactions for a single character you're probably better off not using jobs?

[@CodeMonkeyUnity]

Normally I use the ComponentSystem when its something very simple like here just moving a single Player but yes ideally in a proper game you would make Jobs for everything. I believe the plan is to merge ComponentSystem and JobComponentSystem into one so in the future it'll be very easy to convert them. There is a small overhead when creating the job and their goal is to bring that down as much as possible. In terms of spawning prefabs you can do it with Burst but you don't do it with EntityManager.Instantiate(); You do it with a EntityCommandBuffer.Concurrent

[@andrewshandle]

@@CodeMonkeyUnity I definitely understand that for input, since Job or otherwise, it'll pretty tiny, it's not like movement, rotation or pathfinding which might influence 10s of thousands of entities (depending on your game of course). I should probably stop worrying around a tenth of a millisecond here or there with small Systems and Jobs. ;) Keep up the good work, I find these videos incredibly helpful.

@@alcofribasnasier1838 I know and I've done that myself. The question was do subscenes fix the floating origin problem. Also congrats on 50 lines of code, but I doubt that works for larger projects.

[@ODCrab]

Cool concept. It seems a lot cleaner than having scenes that are only whole if you remember to load in it's sibling scenes. And I never even thought of doing LOD's for entire scenes. I feel like you should have left a disclaimer when you just cycled through the whole sub-scene array to find the closest ones. That is bound to get slow when you have hundreds of these things. Its a weird problem to solve in code. So I think I would add a collider to each sub-scene and put them on a "sub-scene" physics layer. Then do a sphere cast with a layer mask for the sub-scene layer, from the player's position to find which ones are close. Sort of like a radar.

[@CodeMonkeyUnity]

Sure if performance becomes an issue you could build some colliders or just simply test the distance only once per 5 seconds instead of every frame.

Can subscenes be different sizes or must they remain in a grid of all the same size? Say there is a very large scene where the camera zooms out and you want to contain it all in one scene, but there are other surrounding ones that are much smaller. Would this have any long term problems? Assuming all of the subscenes along side the edge of the largest one still have the same length and there arent any gaps within the map.

[@Lythowastaken]

Just as I needed it, great! One question though; How to handle dynamic objects like enemies? They can't be loaded/unloaded based on the subscene, because they could follow the player for example. And what, if I want to save the state of an object, before it gets unloaded, so when I go back later, the object remains like the player left it? I will surely implement this, but this could be content for some of your next videos =) Keep up those awesome videos! (yea, that were 2 questions ^-^)

[@CodeMonkeyUnity]

SubScenes are only meant for either static entities or entities where the state doesn't matter (like a flock of birds) so if you want some sort of state to persist then don't unload it through a SubScene. As soon as you load it loads from the data on the binary file regardless of what changes you made while the SubScene was loaded.

[@abdelrahmanmohammed9405]

Is it possible to interact with the subscene objects in the game? Like destructing objects, etc...

You could use an external map save file to store booleans for each destructible object to mimic this? IDK how efficient it'd be, but it could be a great start I guess

[@Quaternionuur]

This will unload the asset so they are not in the ram. With occlusion you don't render objects but they are still loaded and take up memory.

This is awesome! I haven't looked into SubScenes and your video is the first time I heard of SubScenes, I have been waiting for DOTS to mature before I rewrite the game engine for YAARRGH!

With your experience using SubScenes and its seems plausible, to have multiple SubScenes of about 10x10x10 size for a 3D procedural world?

When the Subscene is unloaded the objects are destroyed. But you could keep the logic of the NPC in another Entity that is outside the subscene and only have the visual inside the subscene and when that is loaded you look up the current state of the logic Entity to display the visual.

Usually you can identify a certain entity by adding a empty tag component

​@@CodeMonkeyUnity thank you! My Problem was that I hadnt known I can just add IConvertGameObjectToEntity to the subscene gameObjects. there I can add all the tags and whatever I need.
