Excellent channel William, very informative and very well edited content! There is something I want to know and I don't know if you covered it in a previous video but I often find myself wanting to make custom unreal scenes presets. Lets say one for exterior environment (with ELM set up as well as all the good Command lines already set up), one for a studio etc... And it would be cool to just create a project from those custom presets and everything is good to go from the start. :)

[@WilliamFaucher]

Thank you! That's also something I would really like to have. Right now what i usually do is have several level presets. One level per type of lighting. Then I use that as a base, open the level, and save-as something new, and go from there. It's a real pain. Another alternative would be level streaming, but then you'd be overwriting/editing that base lighting preset so to speak. Presets would be lovely. I THINK there are plugins on the marketplace for this though!

[@jeremyshin]

@@WilliamFaucher I'll have a look thank you! Another alternative may be to create a project per template and then you just have to right click and "clone project" if you want to create a scene based on it. So its a fresh new file. But it is not very convenient as well...

[@vfxforge]

just got into ue4 today and your videos have helped alot. I would love to see a run through of setting up a level for best quality rendering for VFX pipe. (render settings, light type, fog & atmosphere ) Theres so many hidden options in UE4, I always feel like I'm missing something. If u'd like to use a character / creature asset in this demo.

OH MY GOD That's amazing, I knew about the Ctrl + L thing (which I actually play around with way too much cause it's really fun) but I had no idea there was a whole lighting manager! Also question, do you know if there's too much of a difference between using a realtime Skylight and the raytraced global illumination? I tend to use both but I'm starting to think it's overkill.

[@WilliamFaucher]

Yeah it's great! No they using both is definitely not overkill, they serve completely different purposes. Skylight gives you full control over the ambient lighting. Raytraced GI is nice, but you have no control over it. You can't adjust its intensity, and sometimes it gives really odd results. It is hard to art direct RTGI. Definitely not overkill to use both though!

hello willian! Thank you very much for the video, now I'm finally going to have the courage to migrate to version 4.26 ... I stopped at 4.24 and gave up, because I couldn't keep up with the fast changes, and personally I didn't have much time to study. If you allow me a personal criticism, I don't speak your language, I use subtitles converted to Portuguese, because I'm Brazilian, I try to understand what you say, but I would like to ask you not to speak so fast, so that my bad English can be used in a beginner way ... :) ... Continue with videos like this ... they are helping me a lot ... Would we have future tutorials on how to light an indoor scene using version 4.26? .. Thank you very much!

[@WilliamFaucher]

Thank you! You have a very good point, I do speak fast! I'll try to speak a little bit slower next time. Good luck!

[@SomeKindOfMattias]

One thing I can really recommend is putting together your own actor encompassing sky, atmosphere etc etc. Then you can hide a lot of complexity, make things easy to tweak, have presets etc. it’s also. really easy then to drop it into your level. Epics sun sky actor is really good tho so might be a good idea just to interface with that

[@WilliamFaucher]

Yeah that's basically what the SunSky actor does, isn't it? Unless I am misunderstanding what you mean?

[@SomeKindOfMattias]

@@WilliamFaucher Well, say you're working on a movie, game whatever. You're probably going to be using a lot, if not the same lighting setup in all your levels. If you make an actor that sets the settings you use, and expose the things you want to tweak (say direct light intensity, fog etc) as instance variables. Then you can drop that into any level and easily recreate the same light environment. You can even use inheritance to have some base lighting and override it for certain scenarios. You can also start build up a library of lighting scenarios you can reuse between projects. Can even put PostProcessing and other configuration in there. Saves a lot of time setting up new scenes/level, and if you need to change something later you can just change it in that actor. Guess you could use sublevels, but this seems simpler. SunSky and Environment mixer are good, but a little bit of the kitchen sink :) Better hide the complexity and boil it down to what one uses. Better to have a instance variable pointing to an SunSky actor and do all the light orchestrating from your own actor.

[@WilliamFaucher]

Ah I see! That's a clever idea. What I've done in the past is simply have a lighting level, that then gets streamed into whatever other level I happen to be working on. Only the lights and whatever is in the lighting level gets referenced in. It's just another way (among many) to do what you just described. Whatever works best for you, there definitely isn't a right or wrong answer here. Thanks for the tip! Always nice to see how others approach different challenges. :)

Hi William I m a new subscriber of your channel and I like this type of great content. Direct, simply and useful. Hope you upload continues series talking about Light setting in UE4. I ve a question for you: I all ready made a current project in 4.25 ver. If i update to 4.26 I put in risk my Proyect?

[@WilliamFaucher]

Hey there! Thank you so much for your kind words! I'm glad to hear you like my content! Definitely more lighting stuff in the works :) What I recommend doing is trying out 4.26, with a copy of your project. After downloading 4.26, open your 4.25 project, and a message will ask you what you want to do. You have the option to simply "upgrade", or work on a copy. Working on a copy means you keep your 4.25 project safe in case something doesn't work well in 4.26. That way you can try 4.26 without fear! You can go back to the 4.25 project any time. Does this make any sense? Cheers!

Very nice William... thanks! one thing NOT related to lights at all... but as to do with terrain and landscape...do you have any tip on how to convert a mesh to a landscape? say u have a terrain mesh MODELED in blender or max.. and you want use that as basis in ue4 but using the landscape feature...i haven't been able to do that.

[@WilliamFaucher]

Hi there! You can easily convert landscape to a mesh, but a mesh to a landscape isn'st possible as far as I know. The quickest way would be to bring your mesh into a free terrain editing software like Gaea, then export as a heightmap. Terrain in Unreal only supports heightmap data. It's kind of a shame but it is what it is!

[@FX_AnimationStudios]

@@WilliamFaucher Yeah thats the same answer i keep getting... too bad indeed :(... The thing about exporting to a height map and re-import that to ue4 I fear it might take a bit of guesswork to match the displacement with the proper heights value no? a bit like hit and miss.

[@WilliamFaucher]

@@FX_AnimationStudios It is definitely a lot of guesswork to get it perfectly. But there is most likely a scientific way of doing it. I'm sure there is a way to get things matching up but it is beyond my knowledge at this point. That said, is there a reason why you NEED the landscape? Is the geo model not ok to use as is?

[@FX_AnimationStudios]

@@WilliamFaucher Yeah in my case (and I believe for Archviz guys also would be beneficial) I have a WHOLE city with road sidewalks modeled in max and it has different elevations... would be nice to be able to convert it to a landscape and use all the goodies Landscape tools has to offer... there is a tool in the marketplace that SUPPOSEDLY converts..but its expensive ($70 or so) and by a few reviews i read..it doesnt work THAT well...

[@WilliamFaucher]

@@FX_AnimationStudios Oof yeah. For specific parts like roads and such, I would 100% stick with geo. But, I would create a landscape and sculpt it to roughly match the geo where necessary. Otherwise Landscape doesn't have TOO many advantages over geo. You can still use displacement and blend materials easily with meshes with vertex painting. The key advantages with landscape include being able to sculpt it, use landscape materials to scatter trees and such procedurally. And better LOD control. But that's about it I think?

[@WilliamFaucher]

That's a very good question, I'm not sure actually! I haven't played around with DMX class actors before. I'm quite uncertain if it will show up. Worth trying out though! So far this manager is still a bit barebones, and you can't really choose which lights can show up. I wish you could assign lights to it.

you r awesome. can you please do a video about aces worklflow in unreal. ACES rendering with movie render queue?

[@WilliamFaucher]

Thank you! Well, my understanding is this: Unreal UE4 working space is implicitly assumed to be sRGB. UE4 uses sRGB linear (given you’re feeding it sRGB colour) throughout the pipeline up to the tonemapping step, at which point it uses RRT -> ODT to output the final tonemapped image. UE4 uses ACES 1.0.3 tonemapper to output the final image. Also worth noting: UE4, internally converts directly from sRGB to ACEScg as required for tonemapping purposes. Hope this helps!

[@Roystoncinemo]

​@@WilliamFaucher hey thanks for the insights and do u know how to export proper aces cg for comp and grading

[@WilliamFaucher]

@@Roystoncinemo In theory the rendered frames should be in ACEScg. But what I seem to remember doing on a previous production was rendering with the "pre-tonemap render color" (or somethign along those lines) as a render pass. Basically this strips away the tonemapper and spits out a linear render. From there, you can apply a lut get a better looking image. It's still not a super streamlined process, a lot of these tools were slapped on like duct tape, as unreal is first and foremost a games engine, and a cinematics renderer second.

[@Roystoncinemo]

And as I said, I'm not even sure this is where my problem originated. It's just the last major thing I did prior to noticing the problem.

@@WilliamFaucher So, I rebuilt everything as far as the lighting goes with the Environment Light Mixer and it's definitely the skylight breaking things. I've found that when adding a Skylight through the ELM there are a number of details panels missing in the ELM interface, even on Normal + Advanced, that are still in the main details panel. The main one here is the Rendering panel which has a checkbox for Visible. When adding a Skylight normally by itself, this is checked ON, but when adding it through the ELM, it is OFF. But you can't know that if you're just in the ELM because the checkbox isn't there. There's a few other panels (sections?) missing as well but they are still in the main details panel if needed. Weird that they'd be omitted though.

You need to play around with the settings! :)
