Best Lighting | The Only Tutorial You Need | V-Ray for SketchUp

setting up the lights correctly is the most important thing in creating professional visualizations if your lighting is done poorly then your materials will not look realistic and your render will be flat today I will create natural and artificial light properly this is my interior scene which I will use during this tutorial let's create a lighting to do this we need to turn on v-ray lights tap just right click somewhere here at the top and check v-ray lights tab remember to check other vray toolbars then the most important icon is visible asset editor let's click on it and let's see that in the lights tab one position has appeared this is sunlight this light is set by default firstly I use different type of light to create a lighting in the scene so firstly I will turn off sunlight just click on this sunlight icon and let's see let it grayed out now I will create Dom light in vray6 we have great features in dome light which we will use during this tutorial let's take a look I click on the download icon over here and place it anywhere in the scene it can be in this place let's see that the new position has appeared I click on the Dom light and on the right side I have properties firstly I need to upload the map it will be hdri map you can download many free hdri maps with a great quality from the website polyheaven.com I downloaded hdri maps from this website and I place them in the folder I click on the texture slots click on the folder icon and I choose Clarence midday 4K map I go to the previous asset and let's see that everything looks correctly I will go outside to show you a great new feature I rotate the view and this is my building let's go to the asset editor and render interactively this is the view outside the window let's see that there is no Dom light in the scene this is because my section plane is turned on here is my section plane all I have to do is uncheck these options display section planes display section cards and display section fails let's see that now it works correctly but let's see that the appearance of the dome light is set automatically we can change it just go to the Dom light properties and here we have option finite Dom let's check it we can notice that the very small Dom light has appeared if I increase the radius we can notice our finite Dom light with the ground let's see that I can increase the radius my finite Dom light is too dark that's why I will change intensity for example to 30 and it looks much brighter I will come a little closer and the view is different let's see that except for radius we have also projection height and ground blend firstly I will focus on the ground blend I will decrease the radius value and let's say that if I change this ground blend value I increase it to one I obtained the sphere if I set it to 0 the shape of the final Dom is different I always set it to 0.2 here we can change the projection height I will increase the value of the radius okay and let's change the height if I increase this value let's see that the height projection is different so projection hide offset is a height of hdri map projection and let's say that changing radius and projection height value I can set the Dom light correctly remember that we can always rotate the Dom light to do this we can check use transform and rotate down light in SketchUp or we can click on the hdri map go to the texture placement and rotate it here in the rotate Edge option and let's see that the Dom light is rotated let's go to the previous asset and set it again I place my building in the surrounding remember that we can use this finite Dom option also in the interior let's take a look I stop rendering process and I go to the scene 1. this is my interior and let's check the view outside the window again I render interactively this is my interior let's see that it's too dark that's why I go to the Dom lights and increase the intensity value to 100. the scene is brighter and it looks better maybe I will change the intensity to 120 and it's brighter 150 and it looks very good remember that we can still change the view outside the window we can change the radius we can change the projection height and play with the scene I will set the Dom light intensity to 120. if you want to brighten the view outside the window you can do this easily just click on the texture slot go to the color manipulation and change color offset and the view outside the window will be brighter okay it looks great let's render the scene I click on this triangle and choose render with v-ray this is our interior remember that you can always change the lighting in the scene by exposure layer just click on the layer icon choose exposure and you can brighten your scene by increasing exposure you can decrease highlight burn to get rid of burnouts and a slightly increase contrast and this is our scene using Dom lights only let's move on and create something new this time it will be emissive material I go to SketchUp and I come a little bit closer let's see that here I have light sources and I can convert the sliding into emissive material remember that you can do the same using mesh light this time I will create emissive material I go to the asset editor and I create new material it will be emissive material firstly I will change the color I will set a warmer color I will set it to 5000 and I change intensity for example 220 and I apply this material to the models I double click double click click free times or press Ctrl a to select all the faces and apply this material to the selection I've created these slides as component in other components this material is also applied I would like to have more control over my scene because I have dome light and emissive material so to do this I will turn on light mix render element I click on the create asset render element and select light mix then I change the light mix properties this group by parameter from individual lights to group instances so my light sources will be grouped so it will be easier to control them in the post-production let's render the scene let's say that the emissive material is visible using the light mix we can control our lights even more I click on the source light mix it's on the right size and let's say that I have fewer position here Dom light which I can turn on or off and self illumination self illumination is emissive material let's say that I can increase increase intensity of this light and also change the color this light was set to warmer color but here I can again change the color of the emissive material I will leave as it was before that's why I right click on the Swatch color icon and I set intensity to one I can increase or decrease Dom light intensity it's time to create additional light let's say that my emissive material is not very intensive we need to add something more for example is light I click on the is icon but before I do that just type is light in the Google search engine and you can notice that there are many free files for example from this side Leon Moon Studios I saved one is light in the folder so I come a little closer I click on the IES light I select the light from the folder I open it and place this light a little bit below the light source it shouldn't be placed in the model because it will not work correctly I need to place it a little bit below the light source and I copy it multiple times I select is light move it to the right side press left Ctrl and it's done I will copy it again and I will copy these three lights to the left side let's say that in the asset editor I have only one position here is light if I right click on is light position and choose select objects in scene we can notice that all the is lights are selected you remember that I copied one is light multiple times that's why I have only one position here and this is is Light Group if I change intensity of this light for example to 10 000 and I change the color I am affecting all is lights in the scene let's see that I will create additional is light to do this I click on the is light icon select the file I open and place it below the lamp I go to the asset editor and let's see that the new position has appeared and again I can change intensity of this light to 5 000. I go to the scene 1 and let's check the render this is our render let's click on the source line mix and new position has appeared ah yes light if I turn on or off this group of light the changes are not very visible firstly I will change the color of is lights remember that you can change this color in the asset editor over here or using light mix you can do this in this place I think that light changes in the light mix are much easier I click on the color and I change the color of the lights okay I can change intensity and we can see the difference I can turn on or off this lights the second is light is this one placed under the lamp again I will change the color of the light and I increase intensity we can notice on the render that this light source under the lamp is visible let's create another light source it will be sphere light placed in this lamp so do this I double click to select this element right click height and I will place the sphere light on this model I click on the sphere light click once drag click second time and place it on the lamp I go to the edit Tab and unhide all the models I go to the asset editor I will decrease the size of the sphere light I think it's too large for example to 5 I can move it down okay it looks fine I go to the scene 1 I will change intensity for example to 50 but remember that you can change the color and intensity in the post-production let's check this in this is our render let's go to the source slide mix let's see that the sphere light is over here I can increase intensity it's visible and I will change the color to the warmer one then I will create the last but not least source of light it will be rectangle light which will be placed in the suspended ceiling I click on the rectangle tool and I place it here on the plane I go to the asset editor this is my rectangle light I can increase horizontal Dimension and move it to the left remember that you can always use scale tool to adjust this rectangle to the suspended ceiling I don't want to see the rectangle Light plane so I go to the properties options and check the slide as invisible so a light plane will disappear let's render the scene and this is our final visualization I go to the source light mix increase the intensity of the rectangle lights I can also change the color and it's done let's see that we have created visualization using natural and artificial lights remember that you can play with the lighting for example turn off Dom light and increase artificial lights and we have Night scene thank you for watching Remember to subscribe to the channel and leave a like if you want to learn more about v-ray for SketchUp visit my website edac.org see you soon bye
