Welcome to the 13th part of the blender 2.8 beginners tutorial series in this video. It’s all about lighting We will check the different light objects we will create a nice lighting for our scene and we will adjust some of the materials so that they fit better to the overall scene in the end and we will adjust the leaf and the fabric material so that the light can shine through this as always you can find the timestamps in the video description below and if you want to follow along Sign up to our resource section free of charge there You can download all the project files textures and videos of this tutorial series and our handy blender two-point-eight shortcut PDF I 1 oz egg here for a city boost calm and let’s get started Alright, my 3d viewport is still splitted into two 3d viewports here. We have the camera view which I enabled with numpad 0 and Here we have the general view and if I hold down the middle mouse button Up here on the header and move this to the side You can see that all the viewport gizmos and the few put overlays are disabled So we only see what will be in the final rendered image up here We still have the looked at viewport shading enabled which is important if you quickly want to create materials and stuff But if we want to see the final rendered image We have to switch to the rendered viewport shading we can do the same thing over here middle mouse button Click and hold move this to the side Enable the rendered viewport shading and right now we are using the Eevee render engine So if I click on this camera symbol up here you can see the render engine is set to Eevee We also have the cycles render engine which we also take a quick look later on So but now our Eevee is enabled that means this is the real-time render engine So as you notice right now, although we don’t have any lamp in our scene we still can see the scene a bit and that’s because the world if I click on this icon don’t confuse us with The material tab down here the world is also Affecting the lighting. It’s basically an ambient lighting we can add here. You can see the color set to gray We can also change the color if we like and the brightness But I just leave at this gray and you can also play around with the strengths but for now We leave it at one later one we to use the strengths to zero because I want to have a pitch black background and only the lamps should affect the scene, but for now when we learn about the different light types It’s better to see a bit of the background here so first of all If you want to add a light hit shift a go to light and add one of those four light types So let’s add a point lamp here move this to the side and the strength of this is too low right now Let’s go to the lamp settings down here when you have the lamp enabled you will see this little light bulb icon And here we can change the settings So first of all, let’s change the power to something like 10, for example Then we can change the color as you can see then we can change the specular you can see we have this little specular here Which should basically? represent the lamp in the reflection because The lamp has no size and no physical size. So there is no light bulb object or something like that And that’s why we have this virtual reflection in here and with a specular we can change the strengths of this With the radio’s we can change the size of this virtual lamp object in the reflection as you can see The circle here you can see how big this should be Then we have the custom distance If I would use this I can basically limit the distance of the light which we will also make use of later on But let’s disable this for now. And as you can see we have real-time shadows here and these you can disable down here and We also have a bunch of very technical settings Which in most cases helps us to avoid some little errors IAM there? But we don’t want to take a look at these right now And we can also see this contact shadow because sometimes you can see that somehow the light is peeking through the shadow where it is Contacting the object and if I enable contact shadow There will be added another shadow on top of the other one and with the distance I can also change the size of this and this adds a little bit more realism to the scene So let’s delete this point lamp and now let’s simply add a sunlight the sunlight Basically simulates kind of a Sun Here the position not so important about the rotation if I would take this you can see how the shadow is changing So basically the line shows the direction where the sun is shining to So and I can change the rotation and as you can see here We also have this specular from the sunlight and this we use if we create an outdoor scene, for example Here we have the same settings We can change the color if we want to have a sunset feel Maybe increase the strings a bit and down here We can also enable the contact shadow if we like so the settings are the same as for the point lamp So let’s delete this one here and add a spot light

Let’s increase the power and as you can see with this light we have this nice spot We have the same settings as before. The only difference here is the spot shape we can change the size of the spot and also how hard or soft the edges should be and The last lamp we have here is the area lamp and this is also the lamp we will use for lighting up our scene so again Let’s increase the strengths. You can see we basically have the same settings over here color power specula The only difference here is the shape. So right now we have a square shape We can either scale it here in the 3d view by using s or by using this viewport widget then you can also see that the size is Changing over here if you don’t want to have a square shape You can also change this to a rectangle to make it wider on one edge but not on the other for example And we also have a disc and an ellipse So and you can also see that the reflection in the object is changing Accordingly if I change this to disc you can see that this has a round shape So let’s delete this lamb and start from scratch First of all, let’s go to the world settings and set the strengths to zero and over here Let’s go to the looked at viewport shading so that we can see the lamp objects better But here in the camera view, we will see how the final scene looks like so let’s select the scene collection over here that all the new lamps which we add will for now be added to the main scene and Not in one of those two collections. Let’s hit shift a and add a new area lamp. Let’s move it up and If you wonder why they are so dark all the time, and that’s because at the beginning of these tutorials we said the scene unit size to 0.1. And I guess because of this the lamp power down here is also relatively low so let’s set this to 10 for now and what I wanted achieve here is a kind of Three-point lighting setup and lighting is one of the most important aspects to make your 3d scene look beautiful so no matter how awesome Your models are how awesome your materials and textures are if you have a boring lighting like this year, for example The whole thing looks just bowing and not interesting at all However, if we now set up the lighting you will see how this will change drastically So let’s start with the backlight, which creates this rim light on our objects So let’s scale this down for now and place it somewhere here behind the objects Let’s rotate it a little bit that this is pointing towards the apples. And in this case I want to have a rectangular shape and I want to make the x-value a bit wider You can see right now We have this nice sharp line here Which is caused by the lamp and this helps us to separate these objects from the background So we basically have a very contrasty separation line here, but we have it only up here I also want to have it on this side here. And that’s why I increase the X size of this now You can see how this also effects these apples over here then as you can see down here this is too bright and that’s why we enable the contact shadow and Increase the distance just a bit then I want to have a orange warm color because I want to have a warm feeling for the image Warm mood and that I achieve by simply changing the color to a warm orange tone So we have the feeling of Sun something healthy friendly something like that. And that’s why I changed the color over here and If I rotate the view you can see from the lamb we have this very sharp line here and everything is brighten up and I want to limit this a bit and that’s why I Enable custom distance and then switch uses quite a bit. You can see then we get this more rounded shape here Not too much because I want to have the shadows in front here And if I lift this up a bit, then you have this nice rounded shape I don’t use a spot lamp here because somehow the Reflection of the spot lamp looks a little bit different than from the area lamp And I think let’s increase the power to 25 watts. So this looks good to me. Let’s Duplicate this shift in D Rotate this somewhere here are more from the front which is kind of the key light Let’s make a square out of this way smaller Let’s set the color back to white by simply setting RG and B back to one I think let’s decrease the power just a little bit and Move it a little bit closer. So This should not be perfectly from the front just a little bit from the side So we see the shape of the objects a bit better

we also have contact shadow enabled because I just duplicated the lamp and Also the custom distance make this a little bit further but not too much It’s nice to have this here a bit darker Then this here because as mentioned before here, this is our main actor in the scene the knife and the cut Apple So it’s nice if we have a little bit more brightness over here and the rest is a little bit darker So now let’s duplicate this lamp once again Put it somewhere here on the other side to basically brighten up the very dark areas here But here let’s lower the strengths quite a lot and here I want to have this Bluish greenish color or something like this. So that is a nice contrast to the orange warm tone So we basically color the shadows here a little bit Bluish and I think if we have this little reflection here this also defines the shapes of the objects a little bit better and In general looks like there is for example a window in the background something like this And this easy we created this is simple yet, very nice-looking lighting setup Remember if I for example just had a simple area lamp So this is basically the same scene with a boring lighting setup and the same scene with a bit more interesting lighting setup So now let’s do some adjustments on the scene and especially on some of the materials to fit the look of the final scene first of all Let’s select the ground here and you can see that we have these lines going on here And if we take a look at the fabric, we basically have this triangle going on here, which is pointing towards this spot here So this we can call guiding lines? so these lines are guiding us to this area here and We have this lines from the wood and I just realized if I rotate the wood a bit To match more this line here this somehow feels a little bit better So as you can see now we have this lines also pointing in this direction This lines pointing in this direction and the whole thing looks a little bit better talking about the wood here Let’s go over to the shading and I just realized that if we take a look from the camera perspective Let’s disable the viewport overlays and gizmos that if we want to concentrate on this air, we are more the background is too bright So we also have this bright fabric here and the even brighter wood material. That doesn’t look that nice So I thought it would be cool to color the Vote a bit. So for that let’s select the wood here down Here we have the boot shader and up here We had the hue/saturation node to color the vote a bit this we will change in a second And first of all, let’s hit shift a and add a color bright contrast node and put it behind the hue saturation value node And now let’s increase the contrast and now you can see we have more contrast in the wood which makes this look even nicer I mean even this helps a lot already as you can see so we can focus more on these objects But let’s also play around with the U and the saturation First of all, I want increase the saturation quite a lot now we have the red color I hold down shift left click and hold on the C value and slightly move this to the side You can see now we can change the color we could have wet wood yellow-green Queen would fit in terms of Complimentary color and compared to the red apple But I played around and I like this mixture of blue greenish a bit more here So if we take a look here this looks like if we have wood with a little bit of blue paint Which was sanded somehow and if we take a look from this side to see the reflections better This looks a little bit too much like plastic. So let’s change the color ramp over here of the roughness a bit more Let’s change this to nearly black so that the very closest spots are really close E And now let’s move this one Way over to this side and then you can see that it looks like if we have just a few spots of paint here Which are glossy and the rest is relatively rough And in this way the whole wood looks way more realistic now, let’s take a look from the camera perspective Make sure that we still see a little bit of the reflections over here and I think to better see the reflections in the front here We should go to the aerial lamp from the background the orange lamp and increase the custom distance a bit You can see it was basically cutting off the light In the front here and now we can see the shadow of the Apple the reflection in the knife and also the Reflection here on the ground a bit better then let’s select the Apple and maybe play around a little bit with the reflection Make it a little bit more colossi in some areas But in other areas a little bit less glossy and with the water drops Then the Apple looks really wet because some of the areas are relatively strong in glossiness

Let’s select the fabric here and you can see over here The holes in side of the fabric are relatively small and I want to see through this a bit more so let’s take a look on the color M which is connected to the all four and add a little bit more black and Maybe a little bit less white. So the chords are a bit thinner basically and then we can see through this a bit better So on the last thing I want to do here on the materials let’s select the leaf is too make the leaf a bit translucent if you take a look at real leaves and the Sun is peeking through the leaves you can see the sunlight on the Opposite side of the leaves and also the shadows and so on and this effect I also want to have here you can see here The light is shining on top of the leaf, but we can’t see anything down here It’s just like basically, so what we do select the leaf and for that we need to add the translucent shader So hit shift a shader and click on translucent and place it somewhere here and for the color of the translucent So basically the color we see on the other side of the leaf. We want to have the same color and Also the same bump map which we connect from down here to the normal input of the translucent shader That’s quickly connected with the surface to see what’s going on here Now we have this bright spot on the opposite side of the leaf So now we want to mix this with the principal shader. So it shift a add a mix shader’ place it here now let’s connect the translucent shader with the first shader import and the principal shader with the second shader import and the mix shader’ output to the surface input Now with the mixed factor up here We can change how much of both we want to have if I set this to zero I only have the upper shader which is the translucent shader and if I set this to one I only have the principal shader and Everything in between is the mixture of both so you can see if I set this to 0.5 We have this run out edges here So and if I go even further the alpha completely disappears and that’s why we have to calculate the alpha After we have added the translucent shader So what we do, let’s simply duplicate the mix shader’ put it back here connect the mix shader’ here to the lower input which is basically everything we set up here and the whole color and everything and with shift a and let’s add a Transparent shader put it up here and connected with the upper input So now if I set this to zero we only use the transparent shader which is just transparent as you can see if I put this to one we can only see the other stuff and now I want to use the Alpha mask the transparent information of this leaf image as mix factor This was basically just a black-and-white image the leaf was white and the outer part was black and Now the black parts will be shown as the transparent shader and the white parts will be shown as all the other stuff here now we have the nice alpha and now we can also play around with this mix shader’ to change the strings of the Translucency and as you can see, this is working And since those leaves are using the exact same material you can see this is changing on both at the same time This makes the whole thing a bit more realistic and maybe we can change the colossi nests a bit It’s maybe a bit too glossy for my taste. So And the same effect we added to the leaf here We can also add to the fabric because this is also a bit of translucent so here I use the same technique first, alloy it shift a had the translucent shader a Mix shader’ behind here and a transparent shader up here and let’s duplicate this Connect everything in the right order The translucent shader I connect with the color and with a normal map down here and the mixed shader for the Transparency so that the transparency is working again. We connect this time with the colour RAM which we connect it to the Alpha Which defines the Alpha Channel? so now you can easily change the factor over here and you can see that the light is Peeking through the fabric here as you can see on the Apple. For example, this fabric is also Interacting with the shadow which on the other side hits the fabric object However, you can see it’s not really interacting with the bowl which is underneath the cloth here and I didn’t find a way to solve this issue. If you find a way. Let me know in the comment section below however We will create our final rendering with their physical based Cycles render engine which will not show these errors here So for real-time display, this is absolutely ok, and if we just add a slight Translucency effect here. We can’t see that strong and then the whole cloth thing looks much better

I think just look here. This looks way better integrated to the whole scene I think so. Now we have this nice scene. We have adjusted the lighting and all the materials and now we can move over to Rendering the scene.
