TV Glow Effect in Unreal Engine 4.19

[@Cine_Coverop]

Some channels are actually better than (paid) online courses. Kudos to you. Thank you for sharing this technique!

[@TheUnrealist]

Glad you liked it, Coverop. If you have other specific things you want to learn, let me know!

[@Cine_Coverop]

Well, I would like to know how can I make particles be affected by the wind.

[@TheUnrealist]

Do you want to use UE4's built-in wind system, or are you just looking for general wind-like movement for your particles?

[@Cine_Coverop]

I want to use UE4's built in wind system.

​@@TheUnrealist HEED MY CALL - can this work with rect lights?????

[@iceddz]

Literally can't smash that like button enough. Your technique of blurring the scene capture, using the center to get an average color, and splitting that into RGB and so on to match the overall color of what's displayed had me laughing hysterically with joy! Using this technique I can put a scene capture attached to my character's flashlight, and make sure it's set to use "BaseColor in RGB (Deferred Renderer only)" under Scene Capture>Capture Source. This allows it to use a capture of the scene in front of the flashlight and exclude lighting data making sure I get color light bounce even when in dark areas. This is the BEST fake Global Illumination technique I've found, and it's definitely impressive to look at. THANK YOU!

[@Gideon_the_Seraph]

i was really struggling to find a way to do this and youtube searching gave me no results. then randomly this perfect video appeared in my recommended. thank you so much. also, for anyone else in the future, this works in unreal engine 5

[@hiQer]

Man this is amazing, this works in 4.25. But what is really amazing is your video is one of the best Unreal tutorial videos out there! Your voice is nice and calm, you show everything very clearly and well.. it's just perfect. Thank you so much for this tutorial. I subbed and will check more videos!

[@mateosanzpedemonte7342]

What a creative solution! Excellent 5 stars!

[@samiam.402]

Are you a god among men? This is the perfect tutorial. There is enough detail that I learned a bunch, but not too much so I got bored. And There are so many nuanced nodes that I never would've thought to use, and it's pretty epic how seamlessly you were able to help me get the effect I was going for.

[@jwallace2913]

Really interesting tutorial, the TV lighting is great but this just opened my eyes to the possibilities using the 2D capture/texture/lighting.. thank you!

[@gavsmith1980]

Thanks for this, one thing I happened across after trying your method, turns out in UE4.20 and beyond they've put in Rect Light sources, which work quite well for glows from larger screens, spotlights didn't give me convincing shadows from one dot space, even when I turned up the length and radius of the source. At the angle I wanted my animation to be viewed from it was extremely obvious that there was only light from the very centre of my screens rather than the edges of the screen too, if that makes sense.

[@jwallace2913]

I also opted for the rect light source and the outcome was much more realistic.

[@loux6153]

thanks you sir, I used your technique for rendering a scene where I had to put a TV and it looks awesome so thanks a lot.

[@Quilavar]

I love your channel, your soothing and calm voice as well as the minimalistic but very effective editing~ I hope that there is more content on the way and look forward to it! You're doing a great job!

[@TheUnrealist]

Thanks for the kind words, Quilly. I’ve been really busy with projects this spring and summer but hope to find time to do more videos soon. If you have topics you’re interested in be sure to suggest them!

[@Quilavar]

Oh, there's plenty :) I think that there are a few general topics that lack presence on YT because they are commonly prefered to do in Unity. I would definately like to see some love for Paper2D or perhaps the new Cloud Anchor function of ARCore. Aside of that I'm always curious about polishing things that raise the general appearance and quality of the project like proper transitions or Camera improvements. And something I bet people would be thankful for might be an absolute bare bones multiplayer project that solely focuses on how to replicate properly. Just a few suggestions :> Greetings, Quilly

[@jennychou9196]

Test with UE5 with rect light (better for TV having big flat screen) other than spot light. Then use Movie render queue to render it. It still works perfectly. Thank you, Unrealist!

[@Texasdudeful]

Thank you brother, works on ue5 perfectly

[@supernova8216]

just for some snuk pops like me, who is having a issue with the black screen and video not being displayed even on editor, what you have to do is go to the corner open project settings search for directX change from directX 12 to 11, this is because the 12 one is experimental and it doesnt support the video player yet.

[@SwitchMaxFX]

Thank you! Works perfectly on unreal 5

[@JohnnyPope]

Seriously good tutorial. Excellent narration, clear steps and awesome result. Thank you for putting this together, its a lot of work to put edited tutorials like this together - much appreciated :-) !!

[@jagoulleminouche6905]

Excellent tutotial, great pedagogie , thank you for your time

[@jchipoco]

Very good tutorial! Thank you very much and congratulations!

[@Politicalmeme]

Can you update this?

[@DylanVanRoost]

Hey, can you make a tutorial about choosing the media to the tv to play that exact video? Instead of just one media

[@kleestrat1237]

Thanks a lot! Really great tutorial

[@Riffrefferer]

For anyone still trying this and you get stuck at Spiral blur having an error, try a "texture object paramater" instead of the "texture object" (worked for me atleast)

[@aaron0405peace]

wait so..if i have 10 screens with different video playing on monitors, i need to repeat this process 10 times??......

[@TriformedGaming]

Great tutorial! Exactly what I was after. Many thanks :)

[@WesselHuizenga]

great tutorial! whenever i build my lighting it acctual builds a white color emiting the whole scene instead of creating the effect

[@visualplus8500]

thanks bro. excellent tutor. this is what i was looking for few days. channel subbed. result is phenomenon. :)

[@hyperrhydra7743]

im getting a failed to allocate shadowmap channel because of overlapping lights, how can i fix this?

[@saeedarjmand]

It shows in Lite, but it fails in rendering animation. What should I do in rendering animation? I used the light function to illuminate the facade

[@The9PointStar]

Just what i needed!! thank you!

[@henritronik_play]

Hello first a great night! Could you help me out of kindness? I would like to know how I would put two videos or more to start together with play the way you do, but when I do the configuration ba Blueprint only starts one I can't start two! Please, could you help me?

[@xServanz]

This is a great tutorial, making everything work. Though, it tanks a lot of frames, making me go from 120 fps to 80 fps. Is there a workaround for this? Cheers

[@smudgybrown67]

Nice one Dude, well impressed =]

[@OniMikeVision85]

That was awesome thank you very much

[@dacarly1330]

So mine works in realtime but not in the cinematic. Do you have any ideas?

[@Tryfieldanimas]

Okey i did all again same steps and tatata it worked :D thanks again ;)

[@Alexotronic]

Excellent Vid! What changed in 4.18 that made the previous method break?

[@TheUnrealist]

Epic implemented a new and improved media playback system in 4.18. In my previous technique, you could use the media player video texture as an input to the SpiralBlur-Texture node directly, avoiding the need to use a Scene Capture 2D actor. But unfortunately, because of the way the new system decodes video, you can no longer use that video texture as an input to SpiralBlur-Texture, hence the need for the Scene Capture 2D actor.

doesnt that make this method slower? seems is adding another pass.

[@gusakerman2648]

Great tutorial! I'm having an issue though, every time i re-open my project the media-texture file goes missing. Which in turn screws up the whole thing, having to redo everything each time. Anyone have any solutions for this?

[@antixian]

add a movies folder in your content folder - put your movies there and then save them. dont put anything else in that folder. try it and see if that helps. if not maybe your drive the file is on goes to sleep or isnt available when you load the project?

[@ZoraJones]

@@antixian hi there! i did this - put the video in the content folder but it still happens. it's the content folder of the particular project, right? drive doesnt go to sleep either :/ what am i doing wrong? thanks in advance!

[@SairentoHiruGuy]

can you create series of tutorials about close combats mechanics and reacting on bite?

[@dejotamezo]

Very interesting source!

[@lordrampenthump422]

im curious... why didnt you make the whole tv setup out on a single blueprint so that you can manage it as one?

[@tresillianofficial]

Is there a way to apply this to a rect light? seems as though this would be better suited? However I try it and its not showing my light function?

[@nathanbernard7640]

Hi! nice video! Does anyone know how to reach the same result with Twinmotion?

[@The9PointStar]

The spot light has to be on Stationaty right?

[@arcdipesh]

but I already have some things in level blueprint ,how to make new level blueprint .I have used unreal 4.24 for architecture visualization

[@RichardAllen7753]

Has anyone gotten this to work with rectangle lights?? I have it working with spotlights but when I try rectangle lights theres a huge shadow! Would be better for big flatscreen LED panels I think.

[@architettomessinagio]

Does it work on android device like Oculus Quest Dev? I think Light Function not supported.

[@JMtheCONQUERER]

I dont mean for this to sound like a stupid question but how do I do this with just an image instead of video? thanks.

[@frankbruning6998]

Has every LED TV, blowing?

[@mavisyesim5951]

Thank you

[@nathansmiddy]

Make sure you do update for 2020 lol

[@tresillianofficial]

YES ^^

[@jwallace2913]

@@tresillianofficial Update for 2022, its exactly the same except you get better results from using the rect light source.

[@sean8306]

awesome video. sus-cribed !

[@nowahblanco9935]

sick

[@alexr.4409]

Is that a reupload?

[@TheUnrealist]

Of sorts. The technique shown in the older video no longer works in UE 4.18 and later. This new tutorial shows a new approach that works in more recent versions of UE 4.

[@alexr.4409]

The Unrealist nice, Thank you for your helpful Videos :)

[@Si-Toecutter]

drag and drop it onto your TV..... yeah well that didnt work, why would it, why would it know which part is a screen

[@gusakerman2648]

That is, if your TV object has a separate mesh for the screen. Otherwise just make a plane the size of the screen and place it precisely in front of it. Then drag and drop onto that plane-mesh :)

[@LyubomirIko]

Why you use CameraCapture2D to capture a movie texture that you already have :?

[@jacobbarrow532]

someone make a video about every time he says media player, it speeds up

[@rudy3dri351]
