When I change my ip to the vpn's ip i am no longer able to create a session.

Here are the steps I’d recommend: 1. Both users should join the same Multi-User Editing session as usual. 2. One user adds the asset pack to their project. This will make the assets appear in that user's Content Drawer, but they may not show up for the second user immediately. 3. The first user should now right-click on the newly added asset folder in their Content Drawer and select RESAVE. Fingers crossed, this should trigger the assets to sync and start appearing for the second user. 4. Once the assets appear for both users, make sure to save your levels as normal. Don’t forget to persist your changes at the end of the session to ensure everything is saved properly. That said, if you’re starting to add new content like asset packs regularly, I strongly urge you to start using Perforce or another source control system. It’s designed to handle changes like this much more efficiently than relying solely on Multi-User Editing.

@ we are trying GitHub but having my teammate pool from GitHub I can see the pack on the website but when he pulls it’s not showing in his content drawer

Why would my engine be crashing when I try to persist or save?

No probs, hope it helps. Yes I am looking at creating a Perforce based tutorial for this

@@makeitinunreal 🙏

@@makeitinunreal hopefully soon 👀

Hi, Yes, your co-worker can join the session later and update their project to the latest state, but ONLY if you persist the changes in the session before they rejoin. Persisting ensures all updates, including any new assets, are saved to the project files and will sync when they connect. If changes aren’t persisted, new assets and modifications won’t appear for the second user. Consider using full source control like Perforce to track new files and keep everything consistent between users

​@@makeitinunreal thanks, no one mentioned this and your comment did clear things out, for the full source control I looked at the documentation but I guess it certainly be more clear if some expert like you share a tutorial.

Thanks!

Glad it helped and appreciate the sub!

Hi, thanks for your comment, it is very much appreciated! Multi-User Editing should generally work on a LAN as long as the devices are on the same subnet, firewalls aren’t blocking UDP traffic, and the correct IP settings are configured. Just to clarify, were you and your teammates on the same local network, or was there a specific issue (like different subnets or firewall restrictions) that caused the problem? The VPN workaround is a great point-I’ll include tools like ZeroTier in the second tutorial I’m making about Multi-User Editing for Virtual Production. Thanks again!

@@makeitinunrealwe are not on the same network and we are still struggling getting into the session. Any tips on how to do it over a vpn would be greatly appreciated

Glad it was helpful!

Sounds like a unity dev here 🤣

@@shengalabu8050 never saw an engine with just click there is not actually optimizations LOL ... UE5 is a junk pieces of crap

@@wizardry-y3q cope.

The gotcha is the very fuzzy temporal shadow artifact you can see below the player when they move around. Its fairly minor here as there are a lot more lights to kinda cover for this but in a scene with a single light where either the light or an object moves fast you will run into temporal artifacts.

lol

Apologies :) Was in a bit of rush to get the video out, i'll make sure to include a right ear next time :)

My right ear was engjoying and I've just realized I've misplaced the speakers xD

@@makeitinunreal Depending on your microphone, in the windows sound settings under recording -> properties -> advanced - you might be able to set your microphone to " 1 channel". That way its impossible to forget to fix this in post.

@@makeitinunreal can my rx 6400 run games with megalights implementations? at 30 fps?

Thanks, I should have been clearer about that in the video, I have updated the description with its current limitations

@@makeitinunreal - Thank YOU for doing the video. It was really informative!

That sucks

as many as you want thats the whole thing about megalights

@@PuniieGodx - That part I understand. Let me re-phrase my question. As I add lights to my scene, what's your gut-feel as to when MegaLights should be considered to be enabled. After I have 100 lights in my scene? 200 lights?, etc. Just wondering if you've done any testing that tells you - "yeah, once you hit about X number of lights in your scene you should probably start thinking about enabling MegaLights."

@@John_atCTS it all depends what kind of light you wanna add i think moveble lights are tougher than other lights if im not mistaken but me personally once 5.5 is out im gonna enable this feature all the time even with less lights just for the performence alone

basically no impact. It's a hardware raytracing trick, if you change the origin of the light it isn't gonna slow down the algorithm. Now if you move all 1 thousand, *maybe* you'll see the GPU's cache miss a bunch and find some stutters, but I doubt it with unreal's pipeline.

add some meshes to the scene like buildings, streets ,,etc and you will see your fps goes down to 50fps on 1080p resolution.

I mean it doesn't really happen in 3d art rendering where you can put as much lights as you want on the scene so i doubt it

@@IstyManame what

@@Dhieen I can open blender for example and use 1000's of light sources with no issues. As anybody else, because blender is free. Yet i don't see it casing any issues. Even by beginners, if anything they underuse light.

That's a beginner issue. Any developer know that thousands of random lights are useless in a scene.

That’s what beginners are supposed to do. It’s called learning.

I'm sure there are many pitfalls associated with this innovation. It can't be that simple.

@@arturpak2787 Yeah, for example you cannot use Megalight if you don't activate hardware raytraced. Also it seems there is an incompatibility with distance field shadows and other stuff

Tbh, that was my reaction when I first saw Nanite and Lumen as well. Both come at the cost of requiring relatively new hardware (as does Megalights). Lumen showed itself to be extremely maleable in terms of performance cost, to a point where from my indie dev perspective, it's always worth "sacrificing" a little bit of minimum specs, which often represent a small fraction of the revenue, in exchange for not having to deal with light baking and getting a substantial visual boost. Nanite showed itself to be very project-specific (in my experience at least) and I believe Megalights will follow that path as well.

Also, shadows of fast moving objects are "blurry" / grainy

Needs hardware ray tracing, so no.

​@@ZacDonald Flagship phones have had hardware raytracing for the last 3 years

@@Tech-is1xy That doesn't mean it is supported or ready in the engine. All of this needs to run on Vulkan which is still in experimental. 5.5 just got a good Vulkan update, but Epic don't even consider it beta yet.

Yeah, the long answer is while there might be some support for ray tracing in mobile hardware, this feature is really demanding and reliant on ray tracing that even if a device could technically support it, the performance and visual quality wouldn't be worth putting in the effort to support it.

Nope, but needs hardware raytracing

@@ZacDonald thx makes sense

At the moment, directional lights are not supported unfortunately.

@@QuakeProBro I have not found a lot of information about megalights, does it only work with lumen? Edit: I checked it , and it does work without lumen

@@NANI_47Bro just download and try your self its one and two steps only
