Update: devforum.roblox.com/t/occlusion-culling-now-live-in-roblox-client/3300953 🔔 Small correction, since a lot of people are saying that Roblox already had this feature: - Roblox has something called frustum culling, which is a system for not rendering objects outside the camera's viewport - By the 'objects in the view frame', I meant objects that are in the camera's viewport, but aren't currently visible (Because they're e.g. hidden behind other objects) - Frustum culling and occlusion culling are different, but also, don't confuse them with different rendering techniques like back-face culling or per-triangle culling Edit: And as I said in the video, this feature only works in Studio (as of right now), and only a few selected games have it live Hope it helps!
You have to consider the wide range of hardware Roblox has to support. Occlusion Culling can be difficult to run on many devices. Roblox already features Frustum Culling which is a less resource intensive optimization. These things are not as simple as you think. I'm quite surprised they have a Beta for Occlusion Culling all things considered.
@@CrusiobTV Tbf Unity 3's occlusion culling was primarily focused on pc and consoles, but it still worked on mobile (Although it was recommended to use frustum culling and LOD there due to it causing bad performance), and they made the occlusion culling features more adaptable and customizable in Unity 5. So it still took Roblox a solid few years to actually release it
@@CrusiobTV let's also not forget the fact that roblox has a custom renderer so they have to do all of it themselves, ever since they switched from Ogre3D.
false, this is actually different from any other engine implementation and its superior to something like unity (unity only supports occlusion culling on static/immovable baked objects in scenes, this is huge because it supports occlusion culling for EVERYTHING realtime INCLUDING physics bodies)
Idk if it has anything to do with that but I think it’s engine was originally a physics engine which would explain the names of some things like “weld” or constraints etc
This is actually insane and you're not giving it the credit it deserves, whilst other game engines like Unity do have occlusion culling as far as I know it only applies to scenes with the culling baked into static objects, this is real time and it works on physics objects too so it's actually *better* than unity
Oo right, culling not affecting physics objects is something I completely forgot about, same with another thing that I didn't mention, which is occlusion culling was at first only a Pro version feature, so that's another plus for Roblox.
Better now than never! This'll be a huge update for the mobile player base. Also interesting how entire objects will either pop into or out of view rather than only rendering specific triangles that are visible. I'm sure there's a reason for this. Great video!
only rendering specific triangles would be way less performant because then you would have to check the position for EVERY single triangle, instead of just one position where the object is located at
@onionymous6127 Valid point! I'm sure there was a point where increasing the precision would actually start to decrease performance like you said, so it seems they settled on the whole part/mesh rendering.
Per-triangle occlusion would be more resource heavy on the GPU and CPU than standard occlusion culling, for low-end mobile devices it can cause a performance drop rather than a boost
Wait, Initially I was happy for it, perfomance good ok I get it, but after you told the building you used as an example (in the presets) had a whole interior not rendered that I really realized what it all meant I wonder how far you could go in detail in a game, and not impact performance, like, what if over 50% of the buildings in your game had interiors? That all would just not render and not impact performance? That’s crazy how you’re now able to do that so easily I was making a big-ish side project, and I was starting to fear having to mess with optimization, my weak point, but now I kinda don’t? The big issue was I like making things detailed, my computer does not I can’t believe we will actually get that, just crazy
That's awesome, if I'm able to do my big game idea this will make me feel better about it being a big map with lots of details etc. For me personally I don't have issues with Roblox because I got a good custom built PC, but my old laptop lags like crap on my map and it's not even that much yet so, it's definitely a issue others will face. If only I could script anything I could think of.. (yes I know having a big game idea as a beginner is a bad idea, but I have that as motivation to learn with smaller projects)
It's actually kinda ridiculous how Roblox doesn't have this feature since now. I mean, most 3D Game Engines already had this in the past for a LONG time ago
Wait so what they mean by releasing it to everybody means that players will have Occlusion. Culling on their devices and not that game developers have to enable it for their games in studio right?
PLEASE HELP ME... I went into beta features, enabled it, AND IT DOESN'T WORK :'( I've tried restaring roblox studio many times but it still doesn't work... I don't really know if it's because I have a VERY slow computer...
The only real question is wither or not the ROblox Game Developers who made games will also use this feature for optimization, or they are not aware of it
The thing is they only added this to the studio currently, it may make development easier for devs who have large game places but sadly this isnt going to help out the casual roblox player.
this is acrually like insane. this is a BASIC optimization feature for ANY 3d engine, and they didnt implement it up until now. i know that roblox engine has lots of legacy things, but this is just unnacteptable...
Because of this update, my phone is supporting future lighting for artificial lights, unfortunately, it seems that it still does not work with Global Lighting
@@Krantworld It's not like that with everything, a custom rigged avatar wouldn't be as easy to split since it can cause issues with armature deform or give you an effect that you're not looking for with e.g. body parts not being connected properly
This might be a dumb question but would this affect reflections? If I have a part with a PBR material that is super reflective and there is a part that you cannot see (so it's occluded) but the mirror reflects to the other side, what would happen?
@@Paul1Rb I'm also curious about shadows, I'm assuming that the parts still physically exist and interact with lighting and draw reflections/shadows but don't render themselves onto the screens but I have no idea how it works, still hyped for it nonetheless
Frustum culling is for rendering geometry that's only inside the camera's viewport, and occlusion culling is for rendering geometry that's currently only visible to you, so if a Cube is covering a high poly count mesh, that mesh's geometry won't be put into the rendering pipeline
optimization update? because there's one week that my roblox are lagging sm, and when I turn on my screen record the lag simple disappears, I don't know how to fix it, I find people having the same issue and none of them know how to fix it.
Yep, that's amazing but some people are saying "what took them so long" or something like that, etc.. Alright, occlusion culling is not easy, especially on a platform like Roblox, since it's not like a single game (well, most engines provide this feature so you don't have to try replicating it in your project), it's brought into the engine and Roblox is cross-platform, which makes it harder. Also, amazing video! 🐤 EDIT: Plus, I love your in-depth explaining.
Thanks! They also use their own rendering system, which prob made the process a bit more complicating, but it still kind of doesn't excuse them, since a technology like this was available years ago, same with existing occlusion culling algorithms and learning resources. (And they're a big tech company after all )
does this affect localscripts? like will it be possible to access parts that are not rendered, in minecraft you can't if the needed chunk isn't loaded.
@@Paul1Rb Holy hell, wait, so that means we will finally get higher fps on roblox?? I'm in since 2014 and this will genuinely make me love playing even more

They need fix the 0.0001 increment random misaligns (position & rotation) issue and would be perfect on optimization
Better now than never! This'll be a huge update for the mobile player base.

This saved my project!!! Now, there’s literally no lags to notice. Before that, I often experienced part lags. Thank you so much!
as soon as they do something good they have to do something bad (they removed threads from multithreading)
O didn't hear about that one yet
when that update came out my studio went as laggy as the word "lag"

Wow dang it, it is unbelievable, finally a worthy update
this is actually a crazy old guess from me in 2017 that this would be real
it seems in some games object stop rendering behind trusses even though trusses are see through

Is there any cons in using Occlusion Culling? Like the delay to replicate Models in the Server to the Client when using Content Streaming?
man this shit been around since quake and you telling me only NOW roblox is adding it?
only took them 10 years to add this very basic fundamental feature into their engine lol
PLEASE HELP ME... I went into beta features, enabled it, AND IT DOESN'T WORK :'( I've tried restaring roblox studio many times but it still doesn't work... I don't really know if it's because I have a VERY slow computer...
No clue, you'd be better off posting about it under the devforum post
how the fuck did roblox run like that without this
this is still a beta feature, but when it's built in to roblox studio, it will become a more optimization tool
The only real question is wither or not the ROblox Game Developers who made games will also use this feature for optimization, or they are not aware of it
Might be a fun fact: I think roblox actually did this with lighting for a while
This will do nothing for me as an update a while ago made individual parts load instead of large chunks which makes crashing very common.
Roblox crashing isn't common for me, you might want to contact the support or inform roblox on the devforum
The thing is they only added this to the studio currently, it may make development easier for devs who have large game places but sadly this isnt going to help out the casual roblox player.
Yet
this is acrually like insane. this is a BASIC optimization feature for ANY 3d engine, and they didnt implement it up until now. i know that roblox engine has lots of legacy things, but this is just unnacteptable...
quick question, they completely disappear or they just become ''transparent''?
It completely removes them from the rendering pipeline, but the object data is prob stored in the memory
That’s awesome and will enable games to be bigger and have more detail.
Yup, W for in-door environments
Finally! I wish the engine had more stuff like this!
the fact that they didnt implement it for so long is a bit concerning... but hey at least we have it now
Because of this update, my phone is supporting future lighting for artificial lights, unfortunately, it seems that it still does not work with Global Lighting
Global lighting might not be as easy to tweak for occlusion culling
Finally, no more lag.
There still might be lag, but it'll definitely be way less
@@Paul1Rb I think there will be a lot less lag, especially the BaseParts that won't be rendered if not seen on camera!
If you were to turn it on would it work ingame too outside of studio?
It’s not in production yet (ingame)
I think after the full release roblox may finally let us use 10k+ triangles meshs ❤
Oo yeah good point, but it might also be a concern with Roblox's storage servers
@Paul1Rb yeah this is also a big problem to roblox
It may not tho , because now everyone just go around it and split the mesh to multiple meshs so it's the same but spliced into more than one mesh
@@Krantworld It's not like that with everything, a custom rigged avatar wouldn't be as easy to split since it can cause issues with armature deform or give you an effect that you're not looking for with e.g. body parts not being connected properly

what is that for?
to reduce lag? only render within your frame?
sorry im just started being devs
im not a dev but im pretty sure this function is to only render the map visible in your FOV, and anything that is off-camera disappears to save fps
It saves the pc from rendering things it cannot see (sending draw calls I think)
Frustum culling is for rendering geometry that's only inside the camera's viewport, and occlusion culling is for rendering geometry that's currently only visible to you, so if a Cube is covering a high poly count mesh, that mesh's geometry won't be put into the rendering pipeline
So in short
It only renders what is on your pov
To save fps? I'm right?
@@Paul1Rb last question please
Does it work in playing the game or only in the Roblox studio?
