Exterior lighting in V-ray5 | | How to Illuminate an exterior scene with Vray sun and Sky in 3dsmax

hey guys it's Hadi and in this video I'm going to teach you how to illuminate an exterior scene with the v-ray Sun and sky but before we start please take a moment and subscribe to the channel and hit the notification bell so you don't miss any of my future tutorials now let's move over to 3dsMax and start the project. okay I've chosen this building for this tutorial which is called Niceto Vega located in BUENOS AIRES Argentina I've put the link into its Archdaily page in the description if you want to know more about it okay to start I'm going to set up the render settings in the common tab we have nothing but the size and I've already changed that when I was setting up the cameras so let's go to the Vray tab and start by adding a Vray material as our override material and I'm also going to disable the displacements so it will render faster as for the image sampler I'm going to use the progressive but let's increase the noise thresholds number up to 0.03 for the color mapping I'm going to use the default Reinhard and I'm going to reduce the burn value down to 0.2 okay as for the GI I'm going to use the default engines brute force and light cache there's nothing to change here but let's just decrease the Subdivs value down to 500 we don't need to change anything in the settings and the elements tab so we're ready to start okay let's start the interactive rendering to see what we have so far as you can see our render is completely black and that's because we don't have any light sources in the scene so let's go to the create panel and select the Vray Sun under the Vray section and start adding the Sun into the scene from the top view here Vray will ask you if you want to use the Vray sky as your environment light and since that is our goal let's just hit OK and see the result okay the next step is to move the Sun up along the z-axis let's go to the front view and move it all the way up to here as you can see the render is overexposed there are two ways that you can fix that the first one is to reduce the intensity on both very sky and very Sun which is not my preferred way but anyway this is how you can do it first open up the environment and effects window and drag and drop the Vray sky into the material editor and make sure to choose instance here now double click on the map and enable this option over here then click here and select your Vray sun now you're able to change all the parameters of the Vray sky regardless of Vray sun but instead of changing the intensity I'm going to decrease the exposure through my camera settings let's select the camera from here and reduce the exposure by increasing the target exposure value I'm going to use 12 for this render it's still a little bit brighter than it needs to be and that's because we still have no materials in the scene so I'm going to keep it as 12 and I will change it later if necessary okay we have a new sky model in the Vray5 and you can find it here this one this new sky system is looking so much more realistic in terms of color and intensity it also supports some below the horizon line which means that from now on you can have the night sky in v-ray which is perfect okay one of the most important parts of rendering is shadows to find the best angle for your sunlight you can easily move the Sun around as interactive render is running it will be different from seeing the scene and it is you who has to decide which angle is more suitable for your project as you can see these shadows are too sharp if you want to get softer shadows all you need to do is to first select the Vray Sun and then increase its size from here okay look what happens when I increase this number up to five all of the shadows are softer now but it is up to you whether you want to increase or decrease it I'm going to use 2.5 for this render the other thing is that you can simulate different hours of the day by moving the Sun along the z axis for example I could simulate the sunset if I move it down to here after moving the Sun if you feel your render is over or underexposed you can once again adjust the target exposure value in the camera settings now let's add some contrast this render I'm going to add a curves adjustment from here and add some contrast to the shadows by making an S-shaped curve like this if you want your shadows to be darker or brighter you can change the intensity on the v-ray sky also increasing the intensity makes the shadows brighter and decreasing it makes them darker I'm going to leave it at 1 cause I'm happy with the result once again let's look at the differences between the improved sky system and this one look how different the colors are I totally liked improved one better all right let's check one of the other cameras once again to change the intensity we just need to increase the target exposure value I'm going to use 11 for this camera for this depth of field effect all you have to do is to enable this option over here and change the aperture I'll tell you all about it in one of my next videos okay I'm gonna change the sun's position to where it was before and render this shot and I will get back to you when it's done okay guys this is the final image without any adjustment layers and as you can see it doesn't have enough contrast and it looks a little bit dull so the first step is to add some contrast in this image by using a curves adjustment so you need to simply click here and select the curves now let's make the shadows a bit darker by moving this handle down a bit and let's make the highlights a bit brighter now to get rid of the burned-out areas we can simply add an exposure adjustment layer and slightly reduce the highlight value okay let's add the color balance layer and add a little bit of bluish tint to the shadows and maybe a little bit of yellow to the mid-tones now as for the last step I'm going to use a lookup table layer and use one of my favorite LUT files which comes with Corona renderer just make sure to disable convert to srgb space first and let's decrease the opacity for a tiny bit and we're done okay this is a good base for us to export it to Photoshop and do some post-production to make it pop a little bit more alright guys thank you for being with me during this tutorial please give it a thumbs up if you find it useful and do not forget to subscribe to the
