Lighting Interiors in UE4

[@ThatRyanManning]

Correction @ 18:30 ; "Static Lighting Level Scale" * "Indirect Lighting Quality" = 1

[@creatorediillusioni]

Would love some tutorial on how to make simple cinematics with unreal 4. Thanks a lot!

[@PlatedGuy]

I really should stop judging tutorials by their view count because it was definitely a one of the best UE4 tutorials I have ever seen :v

[@remon563]

good lesson to learn in life !

[@asr59]

For the filling lights at the end of the video I usually uncheck the "cast shadows" option and also set the "specular scale" to 0 so you don't get any reflection/spec from that light

[@esscee96]

As someone who never tried anything in UE lighting before, this was a perfect beginner video for me! Just the right amount of content and information at just the right pace, and helped me to not feel so intimidated by all the options I saw regarding Lighting in UE4. Thanks a lot for this!

[@jjcaratino]

¡Gracias!

[@yejinxkim]

Any word is not enough to appreciate you. You're the best.

[@amyt2777]

Thank you so much for this, brilliant tutorial - just what I needed. Every time I thought I was gonna have a question, you'd answered it in the next breath. Can't thank you enough for how thorough and informative this was

[@suneilangel]

As someone who is trying to get the grips with Unreal Engine and Sequencer, I found this tutorial very helpful. Thanks for that and yes, you earned yourself a sub today.

[@gibsonplayer87]

Soooo helpful! Lighting has been my biggest struggle in set design and this has helped remarkably! Will be following you for more tutorials. Awesome work and thank you for this!

[@bobcharlotte8724]

With no post process effects.. wow.. just wow. Thank you so much.

[@alexandernguyen2864]

Very few tutorials on lighting here on KZbin, which I think is very important, this is awesome, thanks for the tutorial.

[@Conversion108]

really really useful tutorial. Learned a lot of information I'll be using in my levels in only 35 minutes. Thanks a lot for the video!

[@ssmakx]

Thank You so much for this.. Every aspect no matter how small is explained so well. And in such short time.

Can't express how grateful I am for this! Love the straight to the point, professional approach.. you gained a subscriber for sure man, thank you so much!

[@ThatRyanManning]

Thanks Expod!

[@VH9911]

@Ryan the issue you were having with the point light towards the end was the intensity unit going from Candelas to Unitless. When you click Inverse Square Falloff it defaults from Candelas to Unitless which affects the Intensity

[@simoppi18]

i just wantto say thank you for all of your videos these have been a BIG/MASSIVE help to understand ue4 and what you can do with it so THANK YOU !!!!

[@duythvn]

i have watched like a dozen of lighting tutorials...This one is the best one as it covers all the important aspects and key decisions of light placement, colour, contrast, reflection..in just 30 minutes. Thanks a lot for sharing your knowledge

[@ariondigital8518]

Thanks Ryan, great tutorial, as always. Very helpful on a dark scene I've been fighting with the lighting on.

[@murtazarizvi368]

spot light and rect lights are one of the most amazing additions in terms of lighting.

Hi in your tutorial of lighting part 2 series you mentioned that indirect static lighting level scale x lighting quality should be = 1..but here it is multiplied by the lighting smoothness.. Thank You

[@husifps9305]

This is absolute masterpiece.

[@N3DArtworks]

Damn, crazy sad he does not make vids anymore. Was hoping for an updated video on UE5 -Awesome video btw

[@bobbyr]

Great help! I was using pointLights everywhere. Things looked flat and boring now I added the moon thing and just that made the whole thing pop. I started from scratch and removed my shitty post process also. Thanks alot!

[@GentlyGiantGames]

I've run into that bug with the unitless lighting where when you switch back to inverse, it needs to be cranked way up. I fixed it by setting giving it the old settings and changing to candela. Awesome tutorial, very helpful.

[@alex630710]

Excellent teacher.

[@harshadjoshi3944]

Great Tutorial. Helped me a lot. Please more tutorial like these.

[@SyntheticFuture]

Interesting. I would be tempted to stick a spot or a box light to the screen and give it a bit of a blue color and a flicker to make it look like the screen is on. Hyper stylized maybe some rays from the screen to accentuate.

Wish I knew this channel earlier. I’m very curious to know how would you treat baking with a character moving around the scene. What would you leave real time? What would you bake? Stuff like that, your thought process on not only dynamic environment

[@ThatRyanManning]

Baking lights isn't purely a static thing...persay. When baking lighting, you're also baking volumetric lightmap which moveable objects (like a characters) can take advantage of. In short, there are details you just can't get without baking lighting and it's still good for movable objects.

[@666nevermore]

@@ThatRyanManning thank you for the answer, lighting for me is still quite a mistery and I’m struggling gettin my rhythm on it, as well as a solid theory behind. I was composing some environment using quixel libraries and I think I watched all their breakdowns and I guess all of those artist composed with real-time lighting and raytracing, I guess killing performance. But from what you are saying and from what I’m noticing from your videos, baking actually is not only a matter of performance but also a way to improve lighting quality of an environment. Am I wrong? I think I’m missing something somewhere that isn’t making my brain fit those pieces together

[@ThatRyanManning]

@@666nevermore Exactly! This may sound like a shameless plug, but I cover that exact thing in my RTX Masterclass. academy.thatryanmanning.com/courses/rtx-interior-lighting-masterclass There's a misconception that RTX is the "easy button", when in fact, it's great...but when used in conjunction with baked lighting can yield some pretty awesome results.

[@666nevermore]

@@ThatRyanManning I’m saving this course, in a couple of month I’ll finish my master and if I’m into lighting I’ll for sure follow it. Thank you for the answers Ryan

[@Pierraxl]

When you say you want to turn up " Preview Shadow Indicator " it's allready checked and you turn it off, what does it help for actually seem you don't needed it after all ?

[@ThatRyanManning]

It let's you know your lighting needs to be rebuilt! That's all.

[@jbach]

This is great but why not used instanced BP Spotlights?

[@Dante3085]

Btw while I am watching this ( 24.05.2020 ) the Lighting Profiles pack he is using in the video is FREE on the marketplace. PS: Great video !

[@josephburgan3D]

Such a fantastic video -- Subscribed! Thank you. I do wonder though if you actually mean that in the World Settings, Static Lighting Level Scale and Indirect Lighting *Quality*, not Smoothness, needs to equal the sum of 1.0. If that's so (or not), I'd appreciate the clarification. Thanks so much!

[@juliancastillo]

Hey Ryan, great tutorial, thank you so much. I have a question, do you think using volumetric fog in an interior is a good idea? do you think it would enhance the results?

[@ThatRyanManning]

For sure! Fog, when used in moderation, adds a lot of depth to your scene. Personally I prefer exponential height fog.

[@lilsquirt9889]

Hey awesome tutorial man! Really helpful! But how did you do that Shaft Effect using only the spotlight?

[@ThatRyanManning]

The spotlight in the stairwell has a faux Godray card. AKA "Faking it". You could use atmospheric fog and lightshaft bloom to achieve the same effect.

[@lilsquirt9889]

@@ThatRyanManning Thanks! But I want it in a particular position, the atmospheric fog spreads through the whole level.

[@ThatRyanManning]

@@lilsquirt9889 Then go with fog cards. Easiest way to have that dramatic/isolated control

[@LDT7Y]

Thanks for making this. Very useful tips! I had a question about lighting multiple levels though. We're making a VR game in UE4 which has a persistent level, a start screen level (pick character, load game, etc) and then a handful of game map levels that stream in/out depending on the player location. The map levels are varied environments, so have different sky spheres, weather, etc. In terms of lighting, should we have seperate lighting settings (post process, lightmass importance volume, etc) for each bit of map (with only a skylight in the persistent level, since you can only have one per world)? Or what exactly do you put in the persistent level for a VR open world game?

[@MrVicky409]

excellent video.

[@albertusbodenstein1976]

Ryan, After baking my lighting, everything goes dark. Why does this happen? Is there a place where we can ask you questions directly? Don't want to clutter your channel with questions!

[@wk2414]

when I open this file, it puts me in the sequencer, how do I import the static meshes into the editor

[@mae2309]

Maybe you could help me ryan.. I kindda erased the sphere inside my Modes tab. And now I get an empty box and no sphere. How do I get the sphere asset back. Do I need to uninstall the UE version and make a new installation? I hope not.. Thank you in Advanced

[@TheKwiji]

Wait... So you bought IES profiles on the marketplace? Aren't they free on many light company websites? If I Google for it one of the first links that comes up has like 300 profiles for... Free

[@TheKwiji]

Also if you use IES profiles you can not use static lighting and baking with the lights, it's dynamic only.

[@LucidAnimationTV]

Thank You!

[@TheBoggledMind]

wonderful guide but I do have a question, I have looked at forums and haven't found an answer. Why is it when I get my lighting all setup and done, if i press the "build button" (even if I just build the build lighting in the drop down) everything goes into an almost low detail? any decals I have placed disappear ( the decal itself it there but the "blood spatter" thats attached seems to be invisible) my walls and floors look horrible(quality) and the lighting just looks completely different as well.

[@ThatRyanManning]

Is there a texture streaming pool warning? Could be that textures have mipped down due to limited hardware resources.

[@TheBoggledMind]

@@ThatRyanManning yeh I do have that as well as it saying lighting needs built. I mean I dont Have the greatest rig in the world but it runs fine with the epic graphical setting before I Use the build button

[@ThatRyanManning]

@@TheBoggledMind so the editor has overhead. It happens all the time at our studio (even on beefy rigs) where if you have multiple editor windows open, they'll quickly cause slowdowns or texture memory streaming pool issues. Open the console command and try using r.streaming.texturepool.size 9000. I think that's the command. That'll increase you streaming memory pool and hopefully correct the blotchiness.

[@TheBoggledMind]

@@ThatRyanManning Not sure what I did differently but I my decals and everything were fine after this last build, but the lighting still goes way off. the best way to describe it is I have a very dark map, dimly lit. After I hit Build it almost looks like im in the unlit mode while editing or placing objects. I tried the command line and I didnt really see much of a difference. Thank you by the way for the help I do appreciate it.

[@ThatRyanManning]

@@TheBoggledMind Join my Discord discord.gg/6mqkWKw9 and post some screenshots. Might be able to figure out what's happening.

finally someone without an accent lol

[@djgyrad]

i followed everything you did in the video, but my bake is coming out black in the whole scene.. not at all sure how to fix this. it happens regardless of lighting being static or stationary

[@ThatRyanManning]

If your bake is almost immediate, check that you don't have "Force No Precomputed Lighting" checked; otherwise no lighting will be built.

[@Gillespionage]

Fantastic Vid Ryan! Thank you so much. I was wondering how come you used Spot lights rather than Rect lights for the tube lights. I'd have thought they'd give you a more accurate shape with the Source Width and Height settings. Do Rect lights just behave in a different way? Is the lack of the inner and outer cone a reason to not use them? Cheers!

[@ThatRyanManning]

You can absolutely use rect lights instead of spot lights for baked lighting. Rect lights are not great for runtime (when set to dynamic)...especially if it's for a game environment. So I wanted to show achieving a good look with "cheaper" lights (spot lights). Swapping out the spots out for rect lights is totally acceptable. Just don't use a ton of dynamic rect lights.

[@Gillespionage]

@@ThatRyanManning Awesome. Thank you Ryan

Hi sir. I got 40,000 lights need to be rebuilt in my model.. How can I drop it to few hundreds? Thanks

[@ThatRyanManning]

Select -> Delete.

[@zachchio413]

@@ThatRyanManning sorry I dont get it.. But, the size of the model matters when rebuilding of lights?

[@ThatRyanManning]

@@zachchio413 I was half joking with that comment. :) The size of your model/scene does matter, especially when it comes to light energy/attenuation. However, There's nothing that says you can't have 40k lights, however they can't all be dynamic (scene performance/GPU crashing) and your bake times will be rather long. Without seeing the scene, my suggestion would be to isolate small/insignificant lights that don't add to your scene, delete/hide those, and modify your other lights to be more effective.

Hi Ryan, thanks for sharing this with us. Great video. Question about lightmass: I cannot seem to get rid of seams between my modular pieces no matter how far I crank up my ligting quality and lightmass settings. My UVs are well unwrapped and lightmaps have enough res. Any tips?

[@ThatRyanManning]

Try these settings: badrhinogames.com/screenshots/ryanManning/2019-07-10_10-16-55.png Also, are you baking your lighting at Production level?

[@adamplechaty]

@@ThatRyanManning yep, production level and the engine rendering settings are set to "epic". This is the non-textured scene baked with the settings visible on the right. The seams on the floor are the major culprit here, everything else looks decent (if splotchy sometimes). imgur.com/EmYw6XM

[@adamplechaty]

@@ThatRyanManning so problem solved! It was a bad shading on the mesh. I had to add extra support edges to smooth out the shading and now the seams are gone even on the default lightmass settings. See the difference: imgur.com/xqHLpvH Thanks for the effort, Ryan!

Why we do bake, why we cant do realtime lighting ??... why we always want to bake lighting?

[@Kromm3D]

This is 4 years old, not applicable to Lumen, but always nice to know how baked lighting works, specially for videogames

[@ThatRyanManning]

Baked lighting is still a thing...even with Lumen. Baked lighting is far more performant than realtime. There are situations (such as limited hardware or platforms) that necessitate you should use baked lighting.

[@tiredguy2753]

@@Kromm3D Agreed, Lumen is a wonderful thing but I still think there is value in learning how to use bake lighting. Maybe/hopefully there will be a point in which Lumen can be used all the time (assuming hardware gets to that point) but we are not there yet.

[@jjcaratino]

gracias

[@MichaelGaskin]

Thanks for the video... Question for you... From someone who's not really a lighting guy, I would have assumed that the rectangle light would have been better than a spotlight for those top lights. Are they lacking features that the spotlight has? Thx.

[@ThatRyanManning]

In terms of performance costs, a spotlight is the cheapest. Thus if you're using realtime shadows, spotlights are a good go-to. However, area ligjts will produce nicer ligjting but with the added costs of baking time (Lightmass) and extremely high realtime lighting costs.

[@MichaelGaskin]

@@ThatRyanManning Sorry, I should have been more clear. Epic released a new type of light, the rectangle... I was wondering why you didn't use that for those long tube type lights. Thx.

[@ThatRyanManning]

The rectangle light has been in the engine for a while. For the concepts I covered in this video, you could absolutely use rect lights. Just be aware that using a rect light will increase your light baking times and using a rect light for realtime shadows is not ideal and quite costly (with somewhat of a caveat when using RTX/Realtime Raytracing).
