how to render in Unreal Engine 5

today we're going to be talking about unreal engine 5. if you're like me you like making really cool imagery on the computer and in your artist journey you will discover that rendering can be a very time consuming process well today i want to demystify some of the rendering tools in unreal engine to help you make more educated decisions when you hit that render button now one of the biggest fallacies about unreal engine is that it is real time all of the time to get really good images sometimes you might have to crank the samples up but it should not take as long as a typical super duper long powerful render engine like redshift or octane so we have this scene here that i'm working with in unreal engine and i want to kick you off by starting your first animation sequence so to do that what you're going to do is go into your content folder wherever you would like to save your animation and you're going to navigate to that folder i will typically make a folder called sequences and then i'll just go into my tutorial folder and start by right clicking when i right click i will go up to animation and add a level sequence we can call this rendering demo demo01 you can name it whatever you want so from here what you can do is double click on that and then a sequencer tab will pop up i typically like working in 24 frames per second you could do any of these or your custom frame rate whatever you choose 23.976 is my preferred and then what i will do is i will find a camera in my scene and drop it in now i could just click and drag this in but if you do not have a camera what you can do is slide up to the three little dots lines things whatever they are click on that scroll down to create camera here and use the cine camera actor so once that's in we have a camera we can start looking through it by clicking on perspective and go to our desired camera obviously i have a lot of cameras in my scene but let's just go to this main one so with this camera selected i want to change a couple things after i obviously drag it into my sequencer once the camera is in the sequencer i will go and make things a little bit more cinematic right now it is currently an 11 millimeter camera and typically something like a 35 would just look way better obviously i have master chief standing right there this is part of another project but we'll ignore that for now we can change our focus settings by clicking on this button and then we could make a keyframe by clicking on transform of our cameras and actor in the sequencer add a keyframe by clicking on this little button the little plus sign right here then scroll to the end of the timeline and we'll just move the camera a little bit hold right click w forward and just move add one more keyframe there we can see we'll have a simple camera push in now i already did a more detailed camera move so i'm going to actually jump over to that sequence now and you can see what i have cooking so we're in this new sequence that i have that's a little bit more polished we're not going to be talking about how to create and animate a full level sequence inside this tutorial it's mainly on the rendering but i wanted to get you started just in case you didn't know how to add a camera and get started for what you would need to render so let's just say hypothetically you just finished animating your sequence you have some camera moves you have some characters you have some niagara stuff moving in your scene and it might look something like this so i will click on the little lock viewport camera cut so i can view the camera that this sequence is playing from and then i can hit the play button and see what we're working with it's just a simple camera push forward on the helmet with some dust in the background and i think this looks pretty cool working on a little personal project right now so how are we going to render this well first thing is you have to make sure that you have the correct plugins enabled in unreal engine 5 so you're going to go to the top right hand corner and you're going to go to plugins and this window will pop up this window is all of your plugins we'll type in movie render and we want to make sure that we have movie render queue if you have to render crypto mats you'll want to enable this but we'll talk about that in another video you can close that down once you enable the movie render queue plugin you'll have to restart your engine so do that mine's already enabled so i can just close that now to get to your movie render queue settings you go up to cinematics and move your render queue and this is where you'll be able to drop in your level sequences for your rendered animations so from here we can click on the little render button and then we'll search for our desired level sequence i know i'm going to be rendering rendering in ue5 tut so i will just click on that and i have some base settings already plugged in here however i am going to show you what it would look like if you open it up for the very first time so when you click on the default render settings for the movie render queue this is what it will look like it will have a jpeg and a deferred rendering and then your output so let's analyze this just a little bit so in your output settings what you will see is your output directory this is where you will be able to save your files then you will have your output resolution 1920x1080 is generally what you might do but if you are fancy and have the power go for 4k but we'll talk about that soon next if you need to you can go to your frames and set a custom playback range and set your in and out points in case you have to render out a different frame range for your sequence now most of the time you're going to be changing the output directory and your output resolution i really don't play with a lot of these other settings so output is very useful and this is where you will make your final adjustments for where this is going to be saved and then from there you can click accept and if you just need the base settings you could hit render and the jpeg sequence would look just like this now when i view this i'm actually very impressed with what unreal engine can do and one of the biggest pieces of advice i can give when it comes to rendering an unreal engine is if you're using real-time tools such as lumen or even ray tracing in your viewport what you see is what you get and what you see is what you get is a really nice way to think about it when you're running in the engine it really forces you to think about your lighting in your scene and how you're composing your shots rather than trying to force some magical render settings because really there are none in unreal engine now there are a couple things you can do but we're not going to talk about those features in this tutorial we're just going to be focusing on really good looking viewport renders and how you can get the most out of them i'm going to go up to render and click on the desired sequence i want to render and we have our unsaved settings basically what we've already done now the first thing i will always do when it comes to rendering an unreal engine is set my image export type that is going to be exrs so what i can do is i can delete the jpeg sequence and then go to settings and scroll down to exr sequence now in the compression settings this is the default however for a much smaller file size you can use the dwab and it will still give you plenty of information to work with and the reason why we want to do exrs is that they are 16-bit so there's going to be more color information so if you're going to be doing any color grading or fancy filters in post you will have more data to work with in your image so let's set this to dwab and we can leave that as is we'll also make sure we keep on multi-layer not going to be talking about that in this video but just keep that on in general after that what you're going to want to do is add a couple other settings first i always add the game overrides just make sure that we're getting the most cinematic stuff got this tip from brandon clements also known as glassham studios on the youtubes highly recommend checking him out so he says add game override so we're gonna do that next we're gonna add anti-aliasing so anti-aliasing is gonna give you the most quality in your renders however it will take the most amount of time when you add more samples so let's take a look at it go up to settings and add anti-aliasing to put this in the most simple terms your spatial sample count is how many samples are we trying to make a single still image look good so the more samples that you have in your spatial sample count the better it will make slow objects and still objects in your scene generally speaking i'll keep this somewhere between 4 and 16. you don't really need to go much higher than that next is your temporal spatial count and this is extremely powerful when it comes to fast moving objects in your scene this might include characters or a car or spells or grass or something like that truly the temporal spatial account will add the most quality to your render so this is where you can get a little bit more aggressive however be aware that it will increase your render time dramatically so my biggest recommendation is start off between 4 and 16 but if you have a really advanced scene and you want to get some really good looking renders you might want to bump it up to 32 or 64. anything past that kind of gets hairy and just takes forever and at that render an point or red shift but we're not going to talk about that for this video so i'll set my temporal spatial count to four for now but we might want to add more later the last thing you'll need to know inside your anti-aliasing settings is you will want to override basically unreal engine will use its own temporal anti-aliasing method until the product of your spatial count and your temporal count are greater than eight now what does that mean it's basically saying hey multiply your spatial count so four by your temporal count by four sixteen four times four is sixteen and that means we're gonna have 16 samples for our render if it's going to be less than eight then you won't need to override but just use at least four and four in both most of the time so once your anti-aliasing settings are done we can move on to the next render setting go up to your settings and we're going to add in a color output now if you add a color output and you're not doing any other fancy color grading other than using some basic curves and hue and saturation this is going to be fine you could also work in an aces workflow but for the sake of this video you're just going to click on disable the tone curve now if you do want to render in something like aces or a desired color space then this is where you can add your oci oh configuration i'm not going to talk about how to set this up in this video but basically what you would need to do is enable your ocio choose your ocio object and then set your desired color spaces generally speaking unreal will render in a linear srgb and then you might want to render in aces or s-log or whatever desired color space for this video i'm just going to say aces cg not going to talk about that for you if you're just starting out and you're not doing any of the ocio work i highly recommend just making sure you disable the tone curve now before i go any further i'm going to go ahead and save these settings what we have here is actually a really good base to start getting some really high quality renders in unreal so i'm going to save that by going up to load and save preset in the top right hand corner of the render settings window and then we can just save a preset we can call this tutorial render settings settings01 save now what i'm going to do is i'm going to render this out and show you what it looks like so once i kicked off the render button you'll see a render preview happen on your screen now if you look in the lower right hand corner of your render view you can see your sample count adding up it's still going very fast but because we added those anti-aliasing settings that is where we're gonna add a lot more time to this render so this is gonna take about five to six minutes and this is what it looks like now let's compare this back to the jpeg render but overall i generally will do this base settings of four spatial counts for temporal accounts as my starting place for something in unreal glass is on because this video is taking a little bit longer than i thought but now i want to showcase one final thing and that is the console variables in unreal engine 5. now if you want to push it just a little bit more you can add console variables to do that you're going to click on your settings for your render settings and click on console variables what you'll see here is three settings we're gonna mainly focus on the top row we can add a console variable with this little button right here and it's basically like little lines of code that are very simple to help bring your renders to the next level now the thing about unreal engine is that when you're operating in the viewport in the engine you're making art you typically don't want to turn on a lot of these settings because it will dramatically slow down your process because it'll just start chugging so this is where you can really push things so that when it's rendering you can get that little bit of extra quality without sacrificing your workflow speed so the first and most important one that will improve the quality of your renders is screen percentage so that console variable is r dot screen percentage now this value is best done between 100 and 200 i typically keep mine around 150 to 200 but you have to keep in mind that this is increasing the size of your render buffer basically you're doubling or increasing the size of your render image and then the final render process is scaling it back down to your desired size so if you're going to render a by 1080 and your screen percentage is set to 200 it's going to render a 3840 by 2160 image and then scale it down the reason why you would do this is you get so much more detail because it's taking everything and blowing it up and then shrinking it back down a lot of the little micro jitters of noise ends up getting crunched down as well so this is going to be the most valuable console variable that you could add so let's just set that to 200 now keep in mind if you are doing 4k rendering this will dramatically slow down your render and we're not going to go into highly advanced render techniques today but if you are doing a 4k render you might want to keep this one around 125 after your screen percentage console variable what i like to add is r dot depth of field quality i set that to four so i'll keep all of these in the description of this youtube video but generally speaking you want to just copy them in and then add the value into the column on the right you do not want the number in the console variable text command otherwise it won't work so i'll add my depth of field quality console variable and then i'll add a motion blur quality and i will copy and paste that and set that to four i will add another console variable and i will set the shadow quality to be just a touch higher that will be set to five and from there that is all the console variables that i'm going to add now after i add all those console variables i can hit the render button and this is going to give me the best quality but before i do that i'm going to set this to 3840 by 2160 and then i'm going to set my anti-aliasing settings to a spatial count of one and then a temporal sample count of 16. the reason why i'm bringing my samples down a little bit is i'm rendering such a high res image for this i don't want this to be rendering for weeks on end if you're really going to let something render for more than a couple seconds per frame you might as well switch it to path tracing which is a whole separate beast right now we're really trying to take advantage of the real-time quote-unquote tools that live in unreal so with my console variables added my game overrides my color output to ace the cg my anti-aliasing setup let's double check nothing else i need to add we can hit the render button and a final super high quality render would look like this so once you finish rendering an unreal engine you'll have to do some post processing to your render from unreal you can do that in adobe premiere after effects or davinci resolve because i'm trying to get more of a cinematic color grade look i do recommend using davinci resolve plus you get to take advantage of some of the fun aces workflow things not going to talk about that today but stay tuned for more on that so let's take a look at this first render and see how the jpeg render looks control f on my keyboard will full screen this render and we can play it back looks pretty good looks exactly how it looked in unreal engine and i am very happy with this again what you see is what you get and unreal excels at that so i wouldn't be unhappy with something like this but there's ways in which you obviously can tweak it to make it better so let's jump to the next clip i'll leave the render settings up in the screen here but this is a different version this time we are rendering exrs and i rendered in the aces workspace only doing a color transformation to this clip but i'd say this looks better you're getting a little bit more dynamic range with the scene and a little bit more detail with the object there's slightly less noise my biggest gripe with it is the grass in the background right here you can see that there's some weird depth of field effects happening that i don't like now if we jump to the next render you can see that this grass cleaned up in the corner very very nicely this is where we added a ton of samples this time we did 32 samples in unreal engine and also we used the console variables to help improve the depth of field quality so if we play this back i'd say that this looks very very nice perhaps one of the best if not the best thus far now in the final clip i have here this is a 4k render using the screen percentage at 200 in unreal engine and control f this is in my opinion the best render that we had in this unreal engine session if we play it back there's a lot more detail there's a lot less noise because everything was scaled up then crunch down using that screen percentage with a 4k render gives us really high quality renders and this is generally going to be my starting point now i will mention i have a graphics card or two of them that is very powerful i have two 30 90s so for the technology that i have available to me i'm able to get this extra three percent but let's be 100 honest our eyes are not that big our phones are not that big most of the time people are going to be watching this on their phone or a monitor that is 1920x1080 or 2560x1440 not many people have a 4k monitor sure it'd be nice but let's rewind just a little bit this is the render settings using just the base settings with four samples in the temporal count and spatial count and this still looks super good so my point behind showcasing all of these four renders is that they all look very very similar the best one being this one here is that it's 4k it's screen percentage 200 you can get some really amazing quality you can get that extra little three or four percent however the 90 which is just a base four by four spatial and temp workout looks very good last thing i will mention is i did one extra render and this time i rendered the scene in lumen all the other scenes are rendered using ray tracing and you're gonna get a very different look just because obviously the scene is much smaller we're getting a lot of small micro detail and i found that lumen doesn't really excel with a lot of that micro detail stuff so if we play this back we can see that the helmet reflection is less defined we don't have the main character i don't have to fuss with the lumen settings more but lumen still looks very good and this was actually the fastest render but one big thing i would like to say when it comes to lumen or ray tracing is in unreal engine if it looks good it looks good and just render it out you're the judge of that be honest with yourself most of the time the best render settings in unreal engine come from your lighting your composition and your storytelling but i'll leave it there i hope you learned something about rendering in unreal if you did let me know in the comment section down below if you'd like to join the party and learn more about unreal i make content like this sometimes most of the time subscribe to my youtube channel so you can find said content or let me know that you enjoyed this video by hitting that like button in fact take a baseball bat and beat the beat it just hurt it abuse it but i'll leave it there last thing eat one gram of protein per pound of body weight you'll make some goodbye my friends bye you can add your mask you can add some curves whatever you want this is where you do your final bits and pieces too this is where you would do your final look so then you can make something post it on post it on [Laughter] yep
