How to Make a Camera Overlay in Blender 2.8 for your Twitch Stream | StreamSchool

having a cool camera overlay just gives your stream that extra sense of unique personality and there are plenty of websites online where you can buy premade overlay packages or even find some for free but the only way to get something truly unique is to either hire an artist or do it yourself so today I'm gonna show you how to do exactly that here's an example all you need is a PC some creativity and blender 3d which is 100% free link in the description to download that and at the end of the day the goal of this tutorial is not for you to come up with a carbon copy of whatever I come up with if you want that you can just download my file from the discord the goal is to give you the tools necessary to create your own overlay this tutorial is really just a jumping-off point and I can't wait to see what you come up with that being said let's get started my name is Chris folia I'm your stream professor welcome to stream school okay first things first in blender I'm gonna turn on screencast keys just so whenever I press a button you can see what's happening in the lower left-hand corner of the 3d view that way just in case I forget to mention something you can still follow along pretty easily next let's get our file set up for success for making a cool camera overlay and to do that we're gonna go to the camera settings first go down to film and make sure this renders out with a transparent background by checking this box then we're gonna go down to color management and change it from filmic to standard because we want this to display the full range of colors we want our colors to be true to whatever we select if it's filmic it sort of flattens the color curve which makes a really good color grading later in photorealistic scenes but in terms of graphic design and motion media and whatnot it's just not that great in terms of what we want to accomplish so change that to standard then you want to go down to the lower left-hand corner of the 3d view click and drag to turn this into two panels then on this one hover your mouse over here and hit 0 on the numpad to go to the camera view then to get rid of the outlines and the grid and the 3d cursor on all of that hit the two overlapping circles right here finally hold Z move your mouse over to rendered and then release Z and now this viewport will be shown as a shaded view or a rendered view it'll always show all of our lighting and shadows which is exactly what we want so we can constantly have a good idea of what our overlay looks like then we're gonna select our camera go to the camera settings and change the type from perspective to orthographic there's not any other way to really explain that other than orthographic flattens it out it makes it so things further from the camera don't appear any smaller because we don't want like this really perspective 3d looking thing for our camera over that we want it to look flat so then I'm gonna hit off artery set the rotation LG to reset the location grab my movement widget and just move the camera up so it's not clipping through our cube anymore just give it some height it doesn't matter how high you put it because no matter what everything will appear is the same scale if you drag it too far it's easy to lose track of where it is so don't do that then we're going to rotate around maybe some just to get a better view of this scene but we don't really want this to be a cube so I'm gonna select that and delete that then hit the shift a for add go to mesh and plan then we're gonna hit tab to go into edit mode scale it on up and we don't want our overlay to be a square but I also don't think we want it to be a sixteen by nine rectangle the problem is a lot of people on Twitch don't crop their cameras even though it's really easy and the problem with that is that it's just wasted screen real estate most of the time all people have these wide camera views that show off their dope rooms but it's just wasted camera real estate is not doing anything so for me personally I'm gonna scale it up like this then I'm gonna scale it hit s and then X to scale it on the x axis but I'm not gonna go all the way to a sixteen by nine outline I'm gonna keep it a little bit narrower like that just because I don't personally like wasting screen real estate on my stream but you can make yours wide if you want to that is completely up to you then I'm gonna hit click to set that in place and we're almost ready to get started actually working on the overlay then we just hit ctrl R for adding an edge loop you'll notice that the little yellow line pops up when I hover over an edge and that's where it's gonna cut a new edge so if I hover right there and click it'll cut a new edge but it's still sliding if I move my mouse so then I'm going to right click to set that back to the center so now I just have one new edge added directly down the center we're gonna hit ctrl R again and do that on this axis as well right click to set it and now we have four faces or four squares then we're gonna hit three to go to face select mode or you can also click this button right here then select shift select shift selects shift select then hit I for inset and drag the mouse in words metal create our border and you can make this as thick or as narrow as you want this is essentially how thick your facecam border is going to be so I'm gonna put mine somewhere around there you can always change this later and we're even gonna be adding detail to it so don't worry too much about this right now but then just click to set it wherever you like it best then hit delete and faces that'll give us a nice border like this then we can hit one to go to vertex select or this button right here then we can hit C for circle select then click and drag to delete this entire upper corner here and I'm gonna right click to get out a circle select hit delete and go to vertices and that will leave us with just the bottom corner of our overlay and I promise I'm going somewhere with this I'm gonna hit tab to go out of edit mode click the little wrench right here go to add modifier and mirror then select both x and y you'll notice we have our entire thing back but if we hit tab to go into edit mode and we move one of these corners around you'll notice that it does it on every single axis now so we only have to work on one corner and the entire overlay gets created and this setup right here is the brunt of the work this is essentially where you would want to start in creating your own style of overlay from this point forward in the tutorial I'm gonna be working towards creating like a cool 3d mechanical technology sci-fi looking overall a but I'll point out different tips and tricks and techniques along the way that you can apply to your own style so it matches your stream better so I'm gonna go ahead and hit 7 to go to the top view and let's start blocking out the shape I'm gonna pan around and move down you notice that we're in perspective right now in the 3d view so from the top view and I hit 5 on the numpad I can go to orthographic which is what we really want then I'm going to hit ctrl R to add another edge loop you remember we did this earlier so the yellow line is where it's gonna create the new edge I'm gonna click and then a right-click to set that and I'm gonna move this over like this and out of couple more edges so maybe like that and then I'm thinking to make this like a cool-looking technology overlay we can select that vertice in that vertice then move this down like that and notice that's starting to look kind of cool so then over here I'm gonna select these ones and move them and from this point forward just blocking out the shape is a whole bunch of repetitive tasks so I feel like I don't need to necessarily narrate every single little thing that I'm doing you do want to be careful to make sure that this isn't a concave face though so notice how this goes into the face we want to make sure that doesn't happen so I'm gonna move this out just a little bit or we can triangulate it I'm gonna select that point and that point hit J to triangulate it all a to deselect and now I'm thinking what might also look cool here is if we made the corners pop out a little bit so I'm gonna add some more edge loops y'all knowing exactly how to do that slide it over and you can left-click to set it where you slide it rather than right-click to reset it to the center and it s to scale it X on the x-axis 0 to 0 and then enter and that'll give us a straight line the exact same thing on the top except I'm going to hit s and Y for the y-axis than 0 and now we have a corner down here and I can move these vertices over like this and I just want to make this look like maybe it's constructed at the corner so make this a separate piece later but I'm going to then do yeah let's do like a let's do another edge loop here slide that over we can slide it all the way to get it straight just like that one then bring it back some do the exact same thing right here and we can select vertices and just start moving them around until we like the way that it looks again you focus on making your overlay whatever shape you want to make yours I'm gonna make mine whatever shape I want you have complete creative control here so don't don't just stay here and copy me your overall I shouldn't just end up looking exactly like the one I'm creating but I'm just gonna manipulate the shape to whatever I want and I'm thinking that that looks like a pretty cool I'm pretty pretty cool-looking sci-fi kind of overlay maybe even it even make this diagonal whoo I like the diagonal corners like that so I'm gonna select this vertex right here shift select this one alt M for merge and at last which means the last vertex that I selected and that'll give us a nice diagonal right here like that and you notice again it happens on every single corner at the exact same time and this is a cool shape but it's a one flat color right now so to change that I'm gonna split this up into pieces but before we get there I want to make this overlay sort of 3d I want to give it some shape and since we're an orthographic view on the camera we obviously I don't want to give it like a ton of depth I don't want to make it look like a tunnel like a perspective tunnel but I do want to give it a little bit of depth to make the lighting pop and for that we're gonna add a bevel unfortunately this is a very flat object so we can't double it so to fix that in a non-destructive way I can hit tab to go outside of edit mode go to the modifiers panel which is the little wrench go to add modifier and solidify then I'm going to hit go down to the solidify modifier that just appeared up here is still the mirror modifier scroll down here to where it says offset and we're gonna change that to zero and I'll show you why if we add thickness to it right now you notice it's just extrude straight down I went a little bit far or finished with my mouth um but you notice it just goes straight down I want this - I want the thickness to happen from the center outwards so if we set off set to zero you'll notice that now it scales up and down so it puts our face in the center which is what we kind of want and you can add any thickness you want to this it's not going to matter since we're in orthographic we're not going to get a weird tunnel effect then on top of that modifier you can shrink these down with the arrows we're going to add a bevel modifier and you'll notice that that adds a little bit of highlights and shadows to the edges however you'll also notice that it's beveling you'll also notice that it's beveling these edges as well and we don't want that that's kind of odd that kind of looks weird it looks bad we only want to bevel the really sharp corners like the 90-degree corners so to do that you can go to the limit method on the bevel modifier hit angle and let's change it to 85 just to cover a little bit more than just the corners so if we turn this so looking right here if we turn this to none you notice that we get extra bevels which rounds this out which looks bad if we turn on the limit now it's only bubbling in the hard corners and then we can change the offset amount so it bevels less and you'll notice that this slides really fast when you slide your mouse like this if you want to slide in smaller increments hold shift while you slide it and you'll find that you have a lot more control and you don't want to go crazy with a bevel you just want it to look like it adds a little bit of an edge like this it's now if we zoom out it gives like the sense of depth but it's not going overboard which is exactly what we want maybe maybe even just a little bit thicker but again it's really easy to go overboard with a bevel so now we're gonna start splitting this up and adding some interior lines in detail and to do that we're gonna go to that edit mode by hitting tab and we can turn off the bevel okay we can turn it off or you can turn these off in the modifiers off in edit mode just so we can actually see our faces but that makes us so we can't see the bevel while we're in edit mode so I'm gonna leave these on but I'm gonna hit Z hold Z and go to wireframe mode so I can actually see my object here then I'm going to sue I think I'm gonna add some extra edge loops slide that all the way over and slide it out some just to give us a little bit more corner there like so then I'm going to select those two vertices hit f3 to bring up the search menu and type edge split and you'll notice that now each of these four these are separate pieces essentially a split the edge which also because of our battle bevel modifier created an extra outline piece I created an interior edge or outline it looks very mechanical and sci-fi ish and one do the exact same thing with these ones f3 edge split and that's starting to look pretty cool um so let's do the exact same thing for this piece right here I'm gonna select this vertex hit kay move it until it snaps click and drag out like that maybe click again and hit enter and that'll add another cut case answer a knife tool by the way now that I have these two vertices selected I can hit f3 edge split and now we're splitting this up and it looks sort of like a sci-fi mechanical detail and then we probably want to manipulate the shape some too so for that we can hover over this object right here hit L that'll select adjust that object do the exact same thing with the center piece hit P and separate the selection then you'll notice that we can no longer manipulate these in edit mode we're only editing the thin rails so I'm gonna tab out select just this one so now we're only editing this guy we cannot accidentally select the thin rails which is what we want here then I'll select these vertex points and again this is all personal preference to whatever shapes you want to create on yours I'm just trying to show you the different tools that might be useful for that I'm gonna move these around just a bit and I think that looks pretty cool now it looks like a cap piece almost the other benefit we have to splitting this I'm gonna do the exact same thing over here try to keep these lined up on the edges so there isn't like too much mesh collision or anything cool so now the other benefit to this is if we go back to shaded mode you'll notice that these are all the same thickness but I want these to look like these pieces are holding the frame together so I'm gonna go ahead and make these even a little bit thicker so when we add some ambient occlusion and shadows and stuff later it'll it'll have a little bit of an effect on it so I'm gonna go to the solidify modifier and just change the thickness up a little bit like so which again you'll notice doesn't have much of an effect here but it's beneficial a little bit later so then if I go to the top view we're also going to get rid of the bevel on the end there by just moving these in like so and again I keep repeating this but I'm just I'm just working on what I wanted this overlay to look like and showing you sort of the tools that are available at your disposal so another thing you'll notice is that these are no longer matching so you can just move this up a little bit until it matches or we can select both of them and hit s for scale Y and for y axis and then 0 and that'll flatten that right out but overall this is looking it's looking kind of cool it's basic and I would usually spend a lot more time detailing this up let's move on to shaders to make this look even cooler so we're gonna select the rails right here go to the materials panel and hit new and it's worth mentioning at this point that there are two different shaders that you would want to use in blender and nine overlay the first is the principled shader because that covers all your bases you can make metals you can make glass or maybe I don't know if you can actually do glass maybe you can do plastic you can do all sorts do you can you can do any kind of material you want you can do subsurface scattering for skin whatever it covers all the bases but you have this really large list of shaders here in blender and you don't need to pay attention to any of these for what we're doing today just the principle to be SDF and the emission shader is the other one emission is it's the silent emission will make your objects flat it will make it a solid color or whatever texture you apply it to it so if you want to make something that looks more like it was done an illustrator like it's 2d and has outlines and stuff you would use emission shaders for that to make the solid colors I'm gonna stick with the principle shader today just to just to have that cool shaded look so it looks a little bit 3d and sort of sci-fi alike but I'm gonna change the base color of this to blue any like a nice blue like that you can make yours whatever color you want and I'm gonna select the lights and move it around and you'll notice that this behaves and it looks sort of like plastic if we go to render it over here you notice it looks kind of like plastic it doesn't look particularly special or interesting but we do get kind of a nice gradient from the light and you can move the light wherever you want you can even animate the light if you want to in the end but you notice it looks kind of plasticky and to fix that we just go to the metallic slider and slide that up the only difference between a metal object and a plastic object or any other object is that metal the highlight that's created by the light is the same color as the object while on plastic or something the highlight is generally white so that's the Norris means something it looks metallic and something that looks plastic but I'm gonna move this around until we get something that looks relatively cool again I'm sort of speeding through this at this point clarity picked up enough of your time here and I'm gonna take these again and again it's really easy to add details to this I can just hit ctrl R to do the edge split of three edge split control RF three edge splits and now we have like a cool sort of metal Bhima kind of look so then we're gonna take these and we'll add a nice rubber material something like this and we can up the roughness and we can lower the specular to make it a little bit of a flatter sort of look and when I'm working with these by the way and I used lights I'm usually not gonna use a point light I'm usually going to use an area light the cool thing about area lights if I hit all are to make it to reset the rotation make it point straight down as I can scale this up or down if we have more light coming from more points on the screen you end up with softer overall lighting and it just in general looks nicer and you can also scale it more on one axis than the other overall I think this is looking pretty neat I'm gonna mess with the materials a little bit more on some of these pieces and then one more thing we might want to add to sort of a sci-fi overlay like this after you mess with the shape just a little bit more which I'm a perfectionist by the way I don't know if you could tell but I go go way too hard on these things I think we move these up a little bit more again I'm just messing with my points here you can do yours however you want no I don't like that again a lot of art is just trial and error until you get something you like just mess with it see if you like good at mess with it some more that's with it some more pass on it some more and just just until you get something that you like so finally we might want to add like some little lights or something to this and for that let's say want to add like a little light let's say I want to add a couple lights right here I'll show you one other useful tool you can use in blender so I'm gonna hit shift a mesh and plane to add a plane here I'm gonna add a new material we'll make this one an emission so it's a solid color I'm gonna make this blue to match my general aesthetic then I'm gonna move this over here scale it down scale it on the x-axis so it's sort of like a line then we can move this up which since the whole thing is orthographic it doesn't matter where it is vertically as long as it's above the object and then go into edit mode make this a little bit of a diagonal like so then we can take this hit the wrench go to add modifier and array and just add a few more lights so now we have three lights over here on this side so then the one other thing about this design is how symmetrical it is and a lot of people might not like that so how you can fix that now that we've got the basic shape blocked out is let's say we want this part to not be beveled but we do want this part to be beveled so I would select the object go to the mirror modifier now and hit apply so now this modifier is completely applied anything I do right here is not going to change on the rest of the object so now I can drag this down like that and now we have a good place to put these lights if I scale them down like so and you can add all sorts of different details and things that you want on yours but I think this is pretty close maybe I'll divide this in a couple more areas so to select these vertices and these vertices at f3 edge split to divide that that looks kind of cool I'll do that on the bottom as well so maybe I'll cut like here hit f3 edge split select these ones f3 edge split just to add some more interior lines to this overlay the exact same thing here and again you all have done this a million times in this tutorial by this point so this should be second nature this is all just adding additional details to the overlay and you don't have to make it symmetric you can make this only happen on one corner maybe not another like if it's not the whole thing symmetrical it might look kind of wack anyway but in general one last thing you might want to do is add your logo to your overlay and I'll show you how to do that before we peace out but this has already been a little bit longer than I was anticipating for the tutorial but I can just go to edit preferences go to add-ons and in the search bar type image and make sure import/export import images as planes is check escape out of that then go to file import images as planes I don't know why it's not in my folder for this but I'll just go to that folder [Music] and right here I have my fish logo and I imported that a little bit wrong what you're gonna want to do is file import images as planes and you're going to want to find your image of course man I cannot go I cannot do that anymore wrong but you're gonna want to change this to emit instead of principled so it comes in as a solid color then import images as plans it'll come in and you can just place this anywhere you want on your overlay if I want to put this up top like so we can do that I don't think this really fits in this overlay but I just figured I'd show you how if you wanted to you can also try putting this on the bottom and we can even make our overlay shape match it a little bit better if we really wanted to for that I would do another mirror but that's that's one way you can incorporate your logo into your overlay as well so that being said for for a half an hour of work it's not too shabby obviously we'd want to spend more time just detailing it up adding additional details you can do all sorts of things you can add wires you can add additional colors and segments and things but overall that is how you can set up and create an overlay in blender 3d which again is completely free how cool is that finally to export this all you have to do is go to your camera settings and export settings you notice this is rendering out to 1920 by 1080 that's really big so this is only gonna take up a small portion of your screen so you probably want to do like 50 or 25% for this but anyway and you're also gonna want to take your camera and match the width of your overlay as well so you don't have these wasted transparent pixels that take up CPU cycles in OBS so for that we can go down to our camera settings oh no we just go up here to the render settings again and change the X resolution to make the aspect ratio match then you go to your camera settings and change the orthographic scale to zoom in until it's pretty close then all you have to do is hit f12 to render and go to image and save as find a folder on your computer that you like hit save as image and now you have an overlay again hopefully yours looks different than mine I wouldn't in any stretch of imagination call this done but that is how you make an overlay in blender the next step is honestly just to take it into OBS which I can't show you right now because my streaming PC is currently dead so I'm recording this all-in-one PC and I can't record OBS with OBS that's that's pretty much it I mess around with it guy is messed with the details come up with your own creative looking thing I show you how to move the points around and create the basic outline now it's up to you to create
