Hey guys, in today's video I'm going to be showing you how to optimise your lights in Unreal Engine so that they will only be rendered and active if the player is close enough to them.

Hey Matt, I haven't given you the attention you deserve. I've always managed to stumble into your videos through self learning UE5. every time I have a question, you've got the answer. I've managed to create an almost complete, but functioning game over the last 3 months thanks to your teachings. You're incredibly knowledgeable and I want to recognize you for it! Thank you for contributing so much to the community, and for helping bring people's ideas to reality. Sorry if this was too mushy, but I appreciate your skills!

[@MattAspland]

Thank you so much for your support and kind words! I really appreciate it! Super happy I could help out and teach you the knowledge you’ve got today. I wish you all the best with your future endeavours!

[@MrLasox]

Amazing! Just what i needed. This absoultly also help with the performences like you were talking about. That's just genious because i'm going to be having a huge game with different types of mode. Simple and to the point. Zero trash talk for several minutes or hours for before begins on the tutorial. Zero music that's gives you a heart attack. 10/10!

[@offirbaruch7895]

Simple and to the point (Light) optimization tip. 10x!

[@FlyPimpDude]

Super useful, thanks Matt :)

[@MattAspland]

Happy to help!

[@Helgrind44]

Really useful tip, thank you.

[@MattAspland]

Glad it was helpful!

[@TheHairyDizz]

Thanks!

[@GreenStreamDev]

lovely

[@AllMightyMoose]

Hey Matt, could you possibly do a tutorial on a space to ground transition, it would be really cool to see and I haven't seen any tutorial before

[@KylezUwU]

Great vid. Went from 110-120fps to 160fps.

[@kenalpha3]

Ty

[@malindurashmika8386]

Thanks buddy

[@MattAspland]

No problem

[@Itsme-wt2gu]

Can u add dlls and fsr + antialiasing type selection in your graphics setting series?

[@souhaibbenchaker4824]

Nice! Is there away to achieve the same effect but not only relevant to distance but also relevant to if the light is in the viewport or not? I noticed that Hogwarts legacy is doing something of the sort because I was playing on a lower end machine and noticed that some lights and effects take a bit to load back in if you put them outside of view and then back in.

[@PatrickTheDM]

Another pro tip!

[@MattAspland]

You bet!

[@rifat.ahammed]

Thanks

[@MattAspland]

No problem!

[@bastian.urra_]

I am literally just having this problem with my proyecto, you save me bro 🙌🗿

[@MattAspland]

Glad to hear it!

[@hendra_winata13]

Hello, any ideas how to make a navigable main menu UI using keyboard (Using Arrow Up,Left,Down,Right) dynamically so we didn't need to settings each time we add new things? Thank you!

[@creedence999]

i think this is great for movable lights, since they consume a lot of the graphics!

[@Itsme-wt2gu]

Can u make a tutorial series to make a game like man of medan

[@wickwill6628]

Hey Matt, would there be any way to apply this same effect but to objects? I'm using a cube for my lights with an emission on it and it doesn't seem to have the same setting as the lights does. Is there any workaround for this? Thanks in advance you've already helped me a lot so far with all your other videos!

[@sauvik2473]

Guess you can just turn visibility off/on

[@Achillez098]

Thanks Matt, great tutorials as always! I have a request: HOW TO HIDE CURSOR, and how to LOCK CURSOR IN GAME WINDOW For the game jam, I used the Set Show Cursor Node for Player Character 0, in order to show/hide the cursor for various events (open/close menus). But for some reason it doesn't work, cursor still shows up, and only disappears after the player presses LMB or RMB once. Also, I get the sense that if the cursor is at the edge of the screen, LMB and RMB inputs stop sometimes. Is there a way to keep the cursor INSIDE the window? Thank you so much man!

[@MattAspland]

I can add those onto my list mate! Just quickly now, the mouse only disappearing after clicking your mouse buttons will likely be your input mode. If you are doing this in a widget, you’ll want to set the input mode to game and UI, with the UI being your widget. Hope that helps :)

[@EnchantYoutube]

Can you do a slender man AI tutorial it would be a ton of help!! and would deeply appreciate it!! Thanks!!

[@hendra_winata13]

One more question, I have a room and outside the room there is window. If i am inside the room, light still got rendered and impact performance. But, i need it to be rendered when outside the room through window. This method doesn't seem to work for me, any idea (currently using data layer to handle this, please give some thought if there is better option) ?

[@GothManLover]

Is there a way to disable a entire mesh when far from player? I don't really mean LOD's/is there something else like that?

[@xenonguillou7105]

Distance culling

[@frictiongamestudio7217]

can we get tutorial on same topic with meshes when player is far mesh will not load when player is close mesh will load

[@rarerex]

You could use world partitioning or lods with an empty

[@tastysnak]

This looks like it would work great with horror games where you want to limit the player's vision.

[@MattAspland]

Great idea!

[@swbftor403]

It does that’s what I got it set up for now!

[@Itsme-wt2gu]

[@ItsRandomGuy.]
