ADDING LIGHTING TO YOUR REALTIME RENDERING with Enscape for SketchUp

what's up guys Justin here with the sketch potentials calm back with another sketch up rendering tutorial for you so in this video we're gonna talk about how to add lights within in scape so I got a question last week as I was going through in scapes new features on how to create lights in in scapes before I get started today's videos brought to you by the sketch of essentials course schedule essentials course is a course I created to give you kind of a start to finish Sketchup training to help you get started fast working with Sketchup so I cover everything from an introduction to the basic tools all the way through more advanced techniques like modeling for layout and interior design and then also I go through some of the details of photorealistic rendering as well so if that's something you're interested in you want to learn a little bit more about Sketchup get some more in-depth training make sure you check that out at the Sketchup essentials comm slash course now let's go ahead and just jump into it alright so to start off the model that I'm using from the 3d warehouse is Villa modern by SZ Kristoff so if you want to download that and follow along you definitely can and what I've done is I've navigated to kind of the upper level of this modern house model so it ought to work really good we're gonna kind of light this living room area with a few different types of things and so to start off I wanted to talk about the three different ways of adding artificial lights within in scape and this is generally going to be true across most rendering software's so there's two different light object types and so the two light object types are point lights and spot lights and then the last is creating an emitter material and so let's go ahead and start off and add some point light to our model so within in scape what you're going to do is you're going to navigate up to your tool bar and there's an option up here for in scape objects and so when you click on this button for in scape objects what that's gonna do is that's gonna let you add a couple different kinds of things into your model so there's four different things in here you can add you can add point lights and spotlights you can add sound sources and you can add proxies and we're gonna focus on the point light and spotlight options right now and so to start off let's go ahead and run in so I'm gonna click the Run button and that's gonna pop this up in this window and that's gonna give me kind of a view of this model and so you can see how right now this is being lit by the exterior Sun within this model so we're getting reflections we're getting light coming in through the windows all that different kind of stuff so what we want to do is first of all we're gonna change our time of day and if you remembered to do that you just hold the shift key and then click and drag your right mouse button and so we're gonna drag this until we get to night time within our model and I'm gonna do a little bit more of a dusk scene just so you have a little bit of this light kind of shining through but you can see how now it's dark in our enscape model and so what I'm going to do is I'm gonna start off and I'm going to add a point light within Sketchup so I'm gonna go back to Sketchup and I'm gonna go ahead and click on this option for point light and then what that's gonna do is it's gonna ask me for two different things it's gonna ask me for the center point so in this case let's say I had a center point right here I just click and then it's gonna ask for the actual location of the object so you can set like a center point and then you can move this down inside your Sketchup model and so you can see it kind of brings in this funky-looking little placeholder basically it's what this is so this is basically a piece of placeholder geometry indicating to you that there's a point light within your model and so what a point light is is it's basically what it sounds like it's a point that emanates light out in all different directions and you'll notice that this also shows up in your outliner here as an actual piece of geometry so now if I was to bring my in scape window back you can see what that did is that basically created a point right here that's lighting my model so you can see how I already have interior lighting within my model based on that point light and another thing to know if you do this is you can copy and paste this piece of geometry just like you can any other geometry so like let's say I use the Move tool and copy mode and I create five different points within this model and then if I bring in scape back in you can see how now I have five different points my lighting is a lot wider in here so you can use this to create as many point lights as you want within your model and to organize those what you can do if you want to do that is you can group all of these using your outliner so like let's say for example I could put these in a group and I could call this group point lights and then a little bit later we could create a group for spotlights as well and so you can see how I have my five point lights in here and another thing to note and I'm gonna try to do a little bit of a split screen here so you can see this so we'll see how well this works but if you were to come in here and you were to reduce the size of all of these using the scale tool you'll notice that the size of the light that's generated changes as well within enscape itself so you can adjust these based on that to kind of tune in your lighting and the other thing I want to note about this is you can also edit these so like if I was to come in here and select one of them for example and I went back inside my group you can adjust the intensity of the lighting using this slider and you'll know that since these are all components they're all copies of the same object when you adjust one of them all of them adjust so note that the size of these objects is adjusting whenever I move this slider so and you can move these lights around if you want to and so one thing I want to note about working with lighting inside your models is you don't want to try to brighten everything up using the brightness of the lights themselves meaning you don't want if you want this to be brighter you don't want to take this and just drag this intensity up to some super-high level because what you're gonna do is you're not gonna get accurate reflections anymore and you're gonna start washing out your materials and making a whole bunch of changes that you really don't want to make what you want to do instead is you want to get these kinda to the point where they would be accurate so you want to figure out what if you were to put an actual bulb in here you would want to figure out what the actual Candela so that would be and get this as close to that as possible and then if you want to adjust your brightness the way that you would do that is you would use your enscape settings so I would click on the settings option and I would go over into my I would stay in my general settings and I would adjust my exposure brightness so that's what you would use and this is generally true across all different rendering programs you want to get your lighting in here as accurately as possible because these actually do calculations based on the real lighting and then to actually brighten things up you just want to adjust your exposure brightness just kind of a note as to how you'd want to do that and so the other thing I want to note is okay this is gray I've got these point lights in here but if i zoom in you can see how there's no actual geometry associated with them within Sketchup so it looks kind of weird you've just got this like glowing point on your ceiling but you don't have any actual geometry associated with it so there's a few different ways that you could do this so let's say for example that I was to put a floor lamp over here so let's go into the 3d warehouse real quick so I'm gonna go to file 3d warehouse and in this case I'm just gonna do a search for floor lamp and a little trick is if you check this box for manufacturer model sketchup has all of its models in here as manufacturer models and I try to use Sketchup models as much as possible for a few different reasons but generally speaking they have smart modeling practices and that sort of thing but what I'm going to do is I'm going to bring in a lamp and in this case we'll just bring in this halogen floor lamp so I'm just gonna click on this and I'm gonna bring this into my model so I'm just gonna click download' and then I'm gonna place it and so one cool thing about inscape by the way is you can see how this automatically added that light in there as soon as I added it to my model so new geometry gets updated dynamically in here but what I can do in this case is I could just come in to the top of this lamp and I could add a point light so I can just come right here and I could just add a point light within this lamp itself and you can see how I'm having a little bit of an issue here because this is kind of showing through on the bottom but in this case what I'm gonna do is I'm just gonna move this up a little bit and probably over a little bit and then I may also adjust the scale and sorry this split screen thing is a little bit difficult but I'm trying to make it so you can see what I'm doing and what I'm adjusting but what we'll do is we'll adjust this up just like this so now if i zoom out and so you can see how what I have now is I have this torch lamp over here generating this actual light so and the nice thing about inscape is this is all real time so you can come in here and let's say you don't like how bright it is you can or you want it to be brighter you can adjust your exposure brightness in here you could also come in and you could adjust that point light just so just by clicking on it you could bring the intensity down to something maybe a little bit more realistic and you can see how that's updating in real time and one other thing I want to note is if you want these to go away so if you don't want to show these for example within your actual inscape rendering you want to turn them off you can just right click on it and you can just hide them and then as soon as you hide them and then you go back into in scape you can see how there's no light coming from those anymore so if you want to turn a light off for whatever reason you can just hide the geometry within your model so the next kind of light I want to talk about is a spotlight so a point light is basically a point in space that generates light well a spotlight is a light that has a direction so if I was to come in here and go back to my in scape objects I would click on spotlight and then once I click on spotlight I could come in here and I could do the same thing where I set a base point then I set the actual point where the light is in space but then my third click you can see how I get this kind of cone in here well the cone is indicating basically the cone where the light is going to be so you can see how I can basically set a point and then set a direction so if I wanted this to be more angled I could set this like this or I could just click on this point and it would just set this and you'll notice that at the base of this there's this little radius in Sketchup that's indicating the radius of the light and where it's gonna be cast so if I was to go in and look at this within in scape itself right here and you can see how I'm basically setting a cone of light right here so my point is right here and it's shining the light down and you can adjust that by clicking and dragging the beam angle so you can see how I can adjust how wide that spot light is using this and you can also use this to adjust your brightness the same way that you did before but these come in here in kind of the same way that the point lights do and that their actual Sketchup geometry that you can copy and paste so like for example if I was to use the move tool and just create a couple copies of this so let's say I was to create four lights and then I was to go back into my rendering you can see how WHMIS updates I now have four distinct circles of light that these would have come from so and in this case you could do the same thing where you could kind of generate a piece of Sketchup geometry to be associated with this you could create kind of a circle and create kind of a can up here so let's say for example probably what I would want to do is I would want to group this so and so I would right-click on this node click make group and then I'll go ahead and replace these other objects with that group and actually you'd probably want to make them components but this ought to work for right now so I'm just gonna use the move tool and copy mode to create three more copies we'll call it two more copies and then you could take all of these and you could just kind of set them flush up against the ceiling to make them look more realistic and one problem you might have as syntheses spotlights are pointing down your material might not look right but we'll take a look at it yeah so you can see how right now these are in here but you can't see them very well because there's no actual light coming from these points and so we'd have to come in here and we'd have to adjust those materials so that they're actually lit up and so that's gonna take me into my last kind of Lights which is emitter materials and so what emitter materials are are they're basically materials so they're not objects but they're actually materials in your model that emit light so let's say for example we'll come back to these cam lights in a second for right now I'm just gonna group those and I'm gonna hide them but let's say that we had a TV on this wall so if I was to just draw a rectangle and then push this out so if I was to look at what in scapes generating right now I have my one light in here remember I hid my spotlights and I just have this kind of like lump on the wall right now well what we would do if we wanted to create an emitter material is you could actually add a material in here so let's say for example that this was a television and I'm gonna fix my material real quick so this doesn't look quite as silly there we go so now that kind of fits on this face so what we would do in this case is we would go into the enscape material editor and we would select the option for self illumination so like if I turn the self illumination off and I look at this in inscape we'll take this back to the middle of the night you can see how there's the only light that we're getting right now other than the exterior light is from our torch lamp that we created over here but if I was to come in here and I was to go into the materials editor I was to select this material and I was to check the box for self illumination what that's gonna do is that's gonna make this material emit light so you can see how this material is basically creating light within your model so you can use this to add materials that add light to your models and one thing I would probably do in this case is I would probably bring the luminance down because you don't want it to be that bright so but you can see how this is still kind of emitting light as a material so what you would do is you would just set this as an emitter and I will note that in a static rendering program this really slows down your rendering especially if you apply this to something that has a lot of polygons in it I haven't tested it a whole lot with high polygons and in scape but it doesn't seem to affect performance in the same way that would have the static rendering program and so what we would do is let's go back and let's so let's go back in here and let's adjust the material on our can light a little bit so let's say for example that I was to come into this can light because you remember there's no light coming from this material I could apply a white material like this color in zero zero and I should have made these components but I didn't so I'll just apply these one by one so I'm basically applying this white material to all of these and then I'll go back to the split screen for a second so you can see my point lights are back in here well I'm gonna check the box for self illumination so when you check the box for self illumination and you have that white material selected it makes that material in emitter so now you have light being emitted from these as well as your spot lights pointing light straight down so and you probably need to bring this brightness down a little bit but you can see how you can generate the effect of an actual light in here using an emitter material and also your spotlights so that's where I'm gonna wrap up this video leave a comment below let me know
