Rendering in SketchUp - Intro to Interior Lighting

what's up guys Justin here with the Sketchup essentials comm back with another sketch up rendering tutorial for you so in today's video I'm going to talk about the types of interior lighting that you can use to create your renders so let's go ahead and just jump into it so as always we're going to be using Twilight renders free hobby version but the principles that we're going to use today definitely apply to other rendering softwares as well I'm the only thing that's really going to be different it's going to be more the differences in controls and finding where everything is and other softwares but generally they're all going to work kind of the same way if you're looking to download the Hobby version of Twilight render you can go to WWE Lite render comm and download the Hobby version that's going to be the free version that you can use in order to do all this stuff alright so basically all I've done is I've created a box so I just model the box in Sketchup and then I came in here and I created kind of a scene on the interior so if I come to the outside here and I hide this exterior wall you can see that I'm inside this shape with my camera view and uh probably the best thing for you to do is once you get everything kind of modeled in here you can go ahead and kind of get your camera view or your camera where you want it to be probably using the position camera option get everything kind of looking the way you want then you can come in here and kind of unhide that back wall just like this so now when i unhit TEVAR ething that wall is closed and then you're just going to come in here you're going to go to view animation and add scene and basically all you're doing is you're just saving your camera viewpoint so that makes it a lot easier for you to get in here and edit stuff that way if you ever get lost outside your box or whatever just like this you can just click on your scene and just go back to it just like that and one thing that is a little bit important to know is you can come up here and click Edit select none' so if you accidentally click on one of these walls you can't really click off of anything you can hit ctrl T or you can go to edit select none so that you don't have anything selected anymore so anyway what we're going to do is we're just going to start with this simple space and all I've got in here is I've got kind of a TV shape on the wall I've got a couple different chairs in here and I've got a light fixture so nothing too complicated and first thing we're going to do oh and one other note when you're doing this you've got your interior like this you can adjust your field of view by using the zoom tool then you can see where it says shift to change field of view if you hold the shift button and click and drag it's going to affect how much of your space you can see with your camera and you don't want it to be all the way back like this because it's really going to distort everything but if you pick something in here where you can kind of see your scene that will get saved as a part of your scenes up here when you add the scene so make sure you adjust that field of view in here so that you can see the stuff that you're working on all right so what we're going to start off doing is we're going to start off by just adding a light in them Twilight render and so the way you're going to do that is you can either go to the extensions and the Twilight render menu up here or you can just use the or you can just use the create light option up here in the actual Twilight render toolbar so I'm gonna go ahead and use this create light option and you can see how as soon as I click on create light what that's going to do is that's basically going to pop up this box in here where you can actually come in here and you can edit your life alright so when you do that when you click on that edit light button it'll click up this box but there's nothing in here yet you can also see how your cursor turns into like this pointing finger and you get this little point on here and basically you're just going to set a new light and the way that you're going to do that is you're gonna have to click three times the first time is you're going to select kind of a reference point so just a point it's not where your light goes but it gives you a point to kind of inference off of so you're going to set a general reference point you're going to click again to set the location of your light so I want my light to be a little bit below the ceiling here and then finally you're going to click somewhere to to set the target of the light or what your lights going to point out so in this case I'm just going to click right here and you can see when I do that what that does that pops up all this different stuff and the Edit light options of Twilight render so now you can come in here and you can actually edit all this stuff and so we'll just kind of run through some of this stuff real quick so there's basically three different kinds of light that I want to talk about right now there are a couple more but for right now we're just going to talk about three basic kinds so the first is a point light and a point light is basically a light that doesn't have any direction so it shoots out light the same in every different direction so it's basically just a point that light comes off of so if you were to place this right in the middle of your model it would point it would emanate light equally in all directions so that's going to be your first kind of light your second kind of light you're going to come over to this type and you can pick a spot light and you can see how your preview your changes because this is a different kind of light so basically a spot light is a light that just shines on a certain point so you can see how when this is a point light it's got this single point of light up here that's emanating light out if you've got a spot light instead having that single point of light basically it's shining the light down on your object just like this so let me run you through a quick render of that just so you can see what the differences are so if I just run a quick render in here and I set this to preliminary and we'll set this to kind of small 800 by 600 just so you can kind of see real quick so if you just come in here you click the play button to render this light so this is going to be your spot light you can see how there's like the circle of light here on the ground right if I close that and I change this to a point light and then run that render again what you're going to find is is the lights going to be different in this model so you can see now you've got this point right here that the light is emanating off of and it's kind of shining on all your different faces in here so this is kind of like if you had like a recessed can lights are if you actually want your light to point at things so and one thing to note about a spot light so if you have this light set to a spot light you can right-click on it or you can sorry you can single click on it and then right-click on it go down to Twilight render and select set light target and basically you can just click wherever you want that to shine so if you want that to shine on your wall over here you can click there if you want it shined on your floor you can basically click wherever you want that to go so now if I run a quick version of that render you're going find me your spotlights going to be more on the wall over there then it's going to be on the floor so you can see it's going to render that right in here so and you can see what that does is that kind of shines because I set this as a translucent material and we'll talk about that in a second but you can see how it's kind of shining through that and it's casting a colored shadow on the wall so anyway those are the first two kinds of lights that I want to talk about in the third I just want to talk about really fast the third kind of light I want to talk about is an emitter and so basically what in the midde is is actually a material in your Sketchup model that emits light and to adjust that what you're going to do is you're going to use your material editor you can select that object and then you can come in here to your templates and you can select emitter and you can set what kind of emitter you want this to be so you can basically set this so the blue color in your model is going to emit blue light and you can adjust the power in here you can adjust a couple different things but you can use this to emit color so now if I come in here and I run a quick render I don't know how good it's going to look on preliminary but we'll give it a shot alright so if I run a quick render in here you can see that it's kind of this blue color and you can see how this is brighter because that's actually emitting light and it's casting shadows and so what we're going to do because this isn't a very bright rendering and this is an important tip when you're moving forward is we're going to use the post process section in here to make this brighter so like for example if I come in here and I set the exposure on this to like 6 or something like that I can turn the gamma back down because it's a little heavy maybe set it to 1 maybe put my exposure to 5 you can see what this does is it basically fills your entire room it's like a blue light and we'll use this more in the future I just wanted to give you a general idea that this exists so you can use materials as light emitters as well so those are the three kind of lights that I want to talk about in this tutorial so I'm going to go ahead and pull this shape back out of here so now let's talk just a little bit about your different options in here so let's go ahead and we'll put a point light back in here about right here so basically what you've got in here is you've got a bunch of settings where you can actually adjust the way that these lights work so like for example you've got the size option in here where you can make that bigger so if you wanted it to be like a four inch light you can see how this got bigger when I did that so you can make your lights bigger and smaller I'm you don't need to worry too much about attenuation right now so power is going to be something that's going to be important because really what you want to do is you want to use realistic levels of light in your models when you're doing stuff like this and so what you can do is if you think about like light bulbs right you can buy like a 40 watt or a 60 watt or different wattages that affect the brightness 100 watt you can buy all those different things and so when you come in here and set that you can see in your preview scene what that's going to do is that's going to adjust your light based on what you set that up so you can use this preview down here to kind of see what that's going to do but you can actually come in here and you can set those either in lumens or watts usually I use watts just because that's what I'm familiar with but you can set that so those are actually realistic lights next thing you're going to talk about a little bit is you can come in here and let's say you wanted this to be an LED light as opposed to like an incandescent light or whatever you can come in here you can select these different options to have different kinds of light in here so that's that's going to be important because each one of these looks a little bit different obviously so you can come in here you can just kind of set the way that that's going to work and then another thing you can do is you can come in here and you can set these two different colors so like let's say for example that I wanted this to be more of kind of a blue light I wanted to cast kind of a blue color what you could do is you come in here you could just adjust this color to affect the way that things are going to look in here so that's get a little bit darker so you can use that to create different effects but one of the things that's really going to be important when you do this is you can actually come in here and you can pull up like a light chart by googling like light temperature chart or something like that like you know if you go by it if you go by light bulbs at like a home-improvement store or something like that they have different light right they have the cool light they've got the warm light different things like that well you can find a chart of those and then you can come in here and you can pick that value like 3500 is kind of a warm light that you find in bulbs a lot of the time so you can type in that light temperature and click this convert button and it'll automatically come in here and it'll select that color of light for you so you can see how this is more of a yellow light in here so now if I come in here and I run this render it's going to look different than it did before now I may have to turn my post-processing back down and put it back to one for now but you can see how this has more of a warm light as opposed to what we had in there before which had a much lower color temperature so you can come in here and you can adjust this in different ways in order to get different looks and stuff like that but a general rule of thumb is just imagine you're buying bulbs at the home-improvement store and think about which ones you'd want in your space and what those would do because that's going to be something that's going to be really important when you're working in your rendering software so other thing I want to talk about is you can come down here and this is your preview scene and it's the same as everything else in Twilight render if it's a green check what that means is it's going to come in here and it's going to render this scene it's going to give you a preview of what this lights going to do but if you come in here you can adjust your different scenes in here so this would show you more like what this light would look like if it was an exterior light so if it was like a parking lot light or it'll put it in here like if this was a like if this is like a desk lamp or something like that so obviously a desk lamp bulb is going to have lower wattage than a big room light and so you can use this for smaller objects and then there's also kind of a wall sconce option so basically it'll show you if this is a wall might lie it what that would do to your model in here so you can use that to look at your different options in here so that's kind of a basic run through the way this works what I'm going to do now is I'm just going to walk you through a couple different renderings we'll try a couple different things in here and you can see what they do and basically the key in this is for you to just kind of figure out the way this stuff works and then apply it to what you're trying to do so like for example I'm going to go ahead I'm going to come in here and you can adjust and move lights in here just like you can any other geometry and Sketchup so you can come in here and you can move them I think you can scale them as well you can make them bigger smaller or whatever you can hide them you can do all those different things in here you can also select them just like any other geometry and delete them so what we're going to do is we're going to add a couple new lights in here just so we can see kind of what the effect is so we're going to start off and we're going to set a point light right here in your ceiling we're going to go ahead and move that point light down just a little bit so it's not actually in the ceiling but what we're going to do in here now I've got my other view is we're just going to create a couple copies of this so like if I move this over here you use the move tool and copy mode just like you would a normal piece of geometry so now I've got four different lights in here so let's go ahead and run run our first render so if I run this render on preliminary what that's going to do is that's going to give me a really fast render of the way this lights going to interact and all that other stuff and again if you ever want to adjust the brightness of your model don't adjust the brightness of your lights in here keep those realistic and then you can use these settings over here to adjust the way that this looks so that you can get the brightness that you want so you can turn these different things down to adjust that I can turn this up to make it really bright so change your exposure and your gamma and stuff like that to change your brightness don't change your life so use this post-processed piece in here to adjust your brightness but you can see what this does is that gives you your four point lights right here along your room and you can see how those cast shadow Oh's with your furniture right here so like let's say I come in here and I adjust my scene real quick so that adjusted my scene so I've got my other view and we'll just run another view or another render but you can see what that's going to do is that's going to shine lights in your room just like this and you can see how it's dimmer under here so this is actually like simulating the way the lights are affected or the way the lights are being treated in your model so this is one one kind of render you can do is you can come in here and you could use a couple point lights so now let's go in here and instead of doing that we'll go ahead and delete those back out what we'll do is we'll add a pair of spotlights so we'll add a light right here we'll make the target the ground just like this and then come in here and just select spot instead of point and I'm going to go back to my office view just like this and you can see that you can affect a few of the other things in here like the way the light falls off as it moved you can adjust the different size stuff like that but we're going to create one of these and then we're going to make a copy and we're going to move that across just like this as well and then we're going to run our render again and take and take a look at what that does for us so we'll come in here we'll click this play button and make sure you're setting this stuff on preliminary when you first start off just so you can create kind of a fast render in here you can see what this does is instead of instead of having your point lights on the ceiling right now instead of got your lights on the ground so it's shining your light down here and your light kind of emits from what you've got on the ground right here and you can do the same thing you can adjust you can adjust your exposure and your different pieces to kind of brighten it up and all of that but you can see how the light acts differently based off of this and remember that the way Twilight render works is once you start applying materials and everything else then those are going to interact in a certain way as well I could be made this TV screen glossy then light would shine off of that you could actually put an image on this too a screen and set it to be in an emitter so you could actually like the room with this TV screen if you wanted to this this is kind of a general overview of the way the point lights and the spotlights work but another thing you could do is you could actually come over to this lamp and you kind of have to adjust your camera a little bit so you can get up in there for what you could do is you could add a light right here in the middle of your lamp so just triple click in here and just add a point light just like this so now what you've got is you've got a light in here like you would if if you actually had a light bulb in here on this lamp so your light is actually going to emit from inside this lamp just like this and then what you're going to want to do is you can see how you've got this kind of gold color on the outside of your lamp just like this so if I come in here and I select that and Sketchup you've got this color DZero for what you're going to want to do is you're going to want to come into the material editor of Twilight render and you're going to want to select that material so you're going to turn the materials editor on you're going to click the little eyedropper and you can click on this material to select it and then what you're going to do is you're going to come down here and you're going to apply a translucent curtain effect to it so what you're going to do is you're going to come down here you're going to find the translucent material option and you're going to select standard curtain and basically what you're telling it is treat this gold material like kind of a thick translucent curtain and so what you're going to get is you're going to get your light shining through this but then it's going to be affected right here by this actual material so it's going to kind of it's going to kind of affect the way that your color looks and then the last thing we're going to do is we're going to use our light editor to change our light color so like for example let's say that we came in here we've got this wife selected but let's say we went out and we bought a hundred watt light bulb but then we wanted to adjust the color to kind of a warm light bulb so like a warm light bulb for example is going to be about thirty five hundred so if you type in thirty five hundred in here and click this convert button you can see what that did is that adjusted the color of the bulb in here so now if I click off of this this is going to adjust the way that this looks you can see how it's more of a warm color in here so now if I come back I reset my scene and go ahead and close out of these and then I'm going to run my render just like this and we'll run it on preliminary because it usually takes longer with translucent materials and everything else but if we run it on preliminary just like this what it's going to do is it's going to give us a view of our room as if we have this light bulb in here as like a real bulb and so I'm going to go ahead and I'm going to turn the exposure up probably down probably to three and you can change your gamma as well so you don't want to make it too bright but you do want to make it kind of look realistic and you can see what this did because it came in here and it did a preliminary render is there's a whole lot of dots in here and what that means is it kind of shot the lights out but it only shot so many and so it didn't quite see enough of these to make this a smooth option so we're going to go ahead and run this on we'll put it on low plus for right now and you can see how down here it tells you what it's doing it's ray tracing and everything else and this is going to take a little bit longer but you can see the quality of your image is going to be better so we can see a lot better what the shadows look like and everything else so you can see what you've got here is you've got kind of a more realistic image with an actual like light bulb brightness in here you've got this actual material in here that's kind of affecting the way this looks and you can see how this material and this light aren't the same color and so what that means is this is adjusting the temperature of the light as it goes through it just like this but you can see how that's casting shadows and everything else so it gives you kind of a cool more realistic look just like this so the final thing I'm going to do is I'm just going to change my other scene I like my other view better you can come in here and set this to more of a glossy material if you want I'm going to go ahead and skip over that for right now but so then I'm going to open up the render option here and this is going to pop up and I'm going to go ahead and set this to a bigger view I want to create a bigger image so probably will fit this to 14 we'll set this to 1440 and then as long as this aspect ratio is locked it will automatically adjust this you maintain your aspect ratio then I'm also going to come in here I'm going to set this to medium plus so that's going to be a higher-quality render and then I'm just going to let it run for a little while and see what it comes up with I already ran my preliminary render to kind of see what everything looks so I tested it before I did my longer render so now I'm just going to hit the play button and see what it spits out and by the way I keep skipping over this render the current selection only it does ask if you want to render what you have selected and I keep clicking no because I want to render everything you can also just deselect everything before you run your render so we'll just let this run for a minute alright so that's kind of our final render and the way that everything looks so that's kind of where I'm going to wrap this video up what you what you would do from here if you were going to continue making this more of a rendering is or more of a realistic rendering is you probably come in here you start applying materials you'd make these couches look a little bit more realistic stuff like that to kind of make the light look right so you kind of take a look at what you like what you don't like and then you kind of go from there so we'll get into that a little further in the future but I just wanted to give you a quick run-through of the way all the lighting works or at least some of the lighting works in rendering so anyway leave a comment below let me know what you thought did you like this and I go too fast for you in any of those sections whether there's something else you would like to have seen I just love having that Sketchup conversation of you guys so make sure you leave that comment if
