UNREAL ENGINE 4 LIGHTING TUTORIAL (UE4) - FREE DOWNLOAD LINK INCLUDED

[@hotcrossandnobuns1850]

The overview of the world settings in UE4 here is really fantastic. I've searched and searched but not found anything nearly as concise as your explanation here. I cannot explain how incredibly helpful this all it.

[@PolygonAcademy]

yea when i started lighting those numbers were a complete mystery to me too haha

[@GTRGG_06]

Hi Jake! Tim does an awesome job explaining how World Settings work in UE4. If you want to get yourself deeper on this, I'd also recommend Unreal Lighting Academy channel on KZbin, it has some insanely good classes about lighting presets and UE4 GI.

[@Chris-ij3jx]

Please can I just highlight how much of a good teacher you are. I've been level designing for a long time but unfortunately got a bit down with my work years ago and have been out of it for some time, but i've recently and finally recovered my love for it. Thank you for helping everyone out with your videos. Although you're not level designer a lot of the art principles apply!

[@realadnoh]

You can put lighting relevant actors in a sublevel and load that one into your normal map as a lighting scenario. So you can toggle with one click (or ingame) with prebakes Day/Night

[@PolygonAcademy]

yea 100% recommend working like that, its how we do it at work, but would take a lot longer to demo in this tutorial, might make a separate video on that! good point :)

For this they were baked as static, but i find setting your vegetation to moveable so it uses the volumetric lightmap samples instead of lightmaps tends to look smoother/better.

[@dankyvomito]

I just came across your channel. Thanks so much I love your content and style. I'd love some future Unreal Lighting videos.

Amazing Tutorial Tim, My Problem still with lightmap uv where i get weird shadows, can you give me some tips and trick to get a perfect lightmap especially with modular building i remodeled my modular more than x20 but still no perfect result and one more question Tim if you don't mind, are modular building (houses with exterior&interior) should be made from a box or plane or doesn't matter and thank you

[@madhav1234567891]

I'm having the same problem, lightmaps are making my life hell.

[@AlexiosLair]

Man, I had the same problem. But I figured major tips: - Make sure on UV Lightmap channel (usualy channel 2) there's no overlapping - Setup good resolution. For UE4 click on Lit go to Optimisation Viewmodes -> Lightmap Density. Play with mesh lightmap resolution, make it green.

[@RevengeGamingREV]

@@AlexiosLair Already did all what you have suggested but still few shadow bleed also as i read many forums topic about lightmap resolution, they always mention to keep lightmap resolution the lower as you can especially if the game you are creating is going to be on console and i don't know if that is 100% true

[@MercStrider]

Really nice work here Tim! Question though, why use a stationary directional light over a static one? I might be misunderstanding

[@PolygonAcademy]

stationary lights will cast dynamic shadows for the first 15000 units around the camera, so stuff like trees will cast moving shadows, and the player and any dynamic objects will cast a shadow, while still baking the GI and light bounces into the static lightmaps. with static you dont get those features. Most games use a stationary for the sun so everything that moves actually looks grounded in the environment with proper shadows :) hope this helps.

Hi there..Thank you so much for this beautiful preset it is so useful..I was wondering if I can transmit between these lighting modes..for example in one shot when the camera starts moving, it is day light and while it is moving forward it switches to the sunset slowly and then the night time something like a timelap. I am trying to show different times of the day in one shot in my animation. I really appreciate your help and again, thank you so much for your tutorials. David

It can be seen very well on the outside, but in the case of archviz, it is not suitable for interiors: Any recommendations?

[@thanoszag6563]

Hi, Thank you, for your very nice tutorials, I have learnt so many :) I have a question, I want to use the night lighting set up. The post-process Volume is a small cube, should I scale it up, at the size of my scene? Additionally, there is no atmospheric fog, is that correct? Thank you again :)

[@PolygonAcademy]

Those presets dont use atmospheric fog but you can add it for sure. The cube size doesnt matter because its set to unbound/infinite in the settings so it effects the entire world regardless of size of the actual volume

[@thanoszag6563]

@@PolygonAcademy thank you for your response. I am facing a challenge, I am working on my laptop that it is not that ''strong''( graphic card and ram), and at the same time, I have created a scene with a couple of buildings, plants and a canal with water ( water is waving). I have set all the presets that I should and then I pressed the build button. But the build lighting process stuck at zero, what would you recommend to change. I have read as a solution to set all the lights to movable and enable the Lightmaps No Precomputed but don't feel that it really works. Thank you again

[@thanoszag6563]

Another problem that I faced was that some of my wall textures were flickering. I read that I had to increase the value of Bounds Scale more than 1. That really helped, but when I build the lighting I got some warnings about this (that some objects had Bounds Scale more than 1) and I changed back to 1. Eventually, I am not sure what I should do. Besides that, I got an error about maps to need lighting rebuild, suppose that If I managed and build the lighting, the error will be disappeared.

[@kuplayfordvalls6781]

Hey Tim, Great content as always! I'm struggling with something and it would be awesome if you could shed some light into the issue, no pun intended hahaha. So my problem is that my lighting changes DRAMATICALLY when going from fully dynamic to baked... I'm still learning UE4 so I like to build a scene and test different lighting setups and then try them out in fully dinamic and baked to see the difference in performance. The problem is that even setting a Lightmass importance volume and adjusting all the Lightmass settings to the same you have in your video my baked lighting looks awful compared to the Dynamic one even tho it's EXACTLY the same lighting setup! Everything looks so much darker and duller... Any ideas on what's happening? Thanks!

[@PolygonAcademy]

Sounds like the gi/baked ao is adding more shadow to the scene, i would select your directional light and skylight and increase the indirect ammount value to atleast 2, maybe even 3-5 on the directional to get more bounce light filling the scene. Try that!

[@cod_cape5483]

[@nicolassakr5201]

Hello, Thank you for those presets they are awesome, I use it for an exterior scene and it looks great but when I come to interior scenes it is too dark we barely can see should we pump up the directional light? or there is something else you can suggest? thanks again

[@PolygonAcademy]

if you are doing interior/exterior scenes, you can either change up the auto exposure histogram in the post process to be something like min 0.2 max 2 or something like that, or add another post process volume inside your building with a different exposure value to raise the overall exposure in the interior. pumping up the directional will make your outside areas too bright, so its changing the exposure that is going to make the interiors look brighter.

[@maxschmidt2897]

Hello Tim ! Love your tutorials, they are very useful ! I have a question about modular kits though. I am also using 3DsMax and I have an issue with the pivot accuracy. There is something about the way 3dsmax is coded that creates a little margin of error with the coordinates system. That is you can never snap it perfectly to a vertex, which eventually creates some spacing issues with my modular kit. Do you know any way to get around this problem or do you export your asstes first in Maya to fix the pivots before getting them in Unreal ? Your help would be of great value. Thanks in advance =)

[@PolygonAcademy]

I usually snap my pivots to grid points in max, not verts. and then also I usually have the corner verts snapped to a grid point as well, or manually enter the values to be clean numbers. never really had an issue with modular kits in max having spacing issues. try snapping to grid, resetting x-form and making sure your grid values where the pivot is are clean without tiny decimal numbers.

[@maxschmidt2897]

@@PolygonAcademy Thanks for taking time to reply ! I will try what you suggest. I noticed the further my assets from the center, the biggest the margin. But even at 0,0,0 you can notice errors of .001. But anyway I'll try to get around this someway ^^

[@llYuki0okami]

How to change glow effect for choosen material without downgrade its emmisive? I like this "fairytale" atmosphere in the Night version, but I would like the selected glowing objects to look more sharp in colors.

[@PolygonAcademy]

Play with the bloom amount and bias settings, but you might have to decrease emissive power to get everything else looking soft and dreamy with bloom, normally you use the bias to make everything else crisp and only the super bright values like the sun highlights and powerful emissive bloom/glow

[@llYuki0okami]

@@PolygonAcademy what "bias settings" do you mean? I see only bias in ambient oclusion but it changes very little. Maybe you ment Treshold under Bloom category? Also I do not understand what are thoose Size scale / #1 size / #2 size etc. under Bloom->Advanced

[@PolygonAcademy]

@@llYuki0okami yea sorry i meant threshold its been a while since i was tuning bloom settings. I belive the size is the 2 elements of bloom highlights, like the bright center part, and then the falloff around those bloomed highlights, how much it spreads.

can you tell me when doing an exterior scene, all the trees should be set to moveable or static, cus once they set to static then the skylight has to baked them which is impossible

[@PolygonAcademy]

you can do both methods but you have to setup your lightmaps for them properly and keep them fairly lowres if you have a lot of trees. I tend to go with setting them to moveable to keep them dynamically lit, its faster and tends to look better.

[@GodOfDes]

@@PolygonAcademy the lightmap for the trees are really bad from 3dmax with datasmith, so i have to use dynamic sun, but what about the skylight, if its stationary the trees got some weird white specular on the leaves, so i have to set the skylight to static, cus i still have buildings to be baked, the exterior secnes are a lot harder than interior to make them look realistic, espesially when dealing with foliage, so can you tell me whats you skylight setup? thanks

Im having troubles with the downloadable asset (night) Iv used built changed the night mode to sunset or day built many time but night mode will still have a bit of sun light

[@PolygonAcademy]

you could try ticking the "force no precomputed lightmaps" box in the world settings panel, hit build, it will clear out all the previous lightmap data, then untick it and re-build lighting. it could be a bug with lightmass when baking. the night settings do have a directional light to simulate light from the moon, if you want a more flat night look you could delete that and go totally based on the skylight.

are your lightmap sizes super huge? I usually give objects 32-64 lightmaps in general, it will greatly decrease your bake times. since the sun shadows are realtime, lightmaps can be small as its only the soft bounce light being baked.

In your Daytime version my emissive materials and fog effect are very little visible, trying to fix this making all other things way too bright.

[@PolygonAcademy]

during daytime light values most emissives wont be super noticeable if you have a realistic setup, think of the vegas strip during the day, the neons are still turned on but you dont notice them, and then at night because the relative light around them is much darker, you notice their emissive value way more. if you want something to be really brightly emissive during a daytime lighting setup you need to crank up the emissive multiplier a lot to make it noticeable. if you are trying this in UE5 with lumen, it will make everything brighter because lumen takes emissive values into account for the bounce lighting .

[@PolygonAcademy]

you could select the fog actor and decrease the density to allow you to see further, the thicker the fog is the more it hides distance details. try adjusting the density values :)

@@PolygonAcademy Even if I set fog density to 0,00001 its still cover the ring below, add to this AtmosphericFog from Day version make my hdri visible, but also make its too much bright, changing Fog Max Opacity in ExponentialHeightFog gives me effect close to what I want
