Real-Time Rendering IN VRAY for SketchUp with Vray Vision! (Detailed Tutorial)

what's up guys justin here with the rendering essentials dot com so in today's video we're going to check out the real-time rendering solution contained inside of v-ray 5. so let's go ahead and just jump into it alright so historically the way that rendering and v-ray worked is you would basically go through here and you would run a singular render of your image so what you would do is you'd click on the button it would render out the image and then if there were any changes that you needed to make you'd have to go back and render that again right so let's say we were to rotate this image a little bit inside of sketchup and we wanted to re-render this we'd have to go back and click the button again in order to have it update and give us a new view which could be really time consuming now there is the interactive rendering built inside of v-ray so if you were to click in here and render with v-ray interactive this would render every time that you rotate around in your scene right it's re-rendering your scene over and over again but the problem is you are still sitting and waiting for results so i can't actually like step into this and move around it's basically a still image that's being generated inside of the v-ray frame buffer and so with a v-ray vision though what's happening is my results are changing in real time so i can actually move the sunlight around in real time i can make changes in real time other things like that and we're going to go and we're going to add some materials and other things like that but you can see how this is much more interactive so i can use the w a s and d keys to actually move around in my rendering or i can also orbit around the scene too so let's take a closer look at the way that this works right so first off let's talk about how to open up v-ray vision so if you look in the v-ray for sketchup menu bar right here notice how there's an option in here for start v-ray vision and so if you click on the button for start v-ray vision what it's going to do is it's going to pop up a window right here that's going to allow you to navigate around inside of your scene all right so let's switch into a side by side mode so i'm going to split my screen i'm going to split my screen so i have sketchup on the left-hand side and v-ray vision on the right-hand side and notice how i can navigate around my model inside of sketchup and my view will also change inside of v-ray vision however if you wanted to explore around yourself you could come in here and you can either click and hold your right mouse button and drag up and down in order to zoom in and out or click and hold your left butt mouse button in order to orbit you can also switch to first person navigation mode so when you do that when you click in here what that's going to do is that's going to allow you to move around like this was a game engine right so i can use the w a s and d keys in order to move around as well as the q and e to go up and down inside my scene then i can hold the left mouse button in order to look around so you can either do your navigation based on what's shown in sketchup or you can actually navigate around yourself inside of this view and so real quick let's take a look at some of our settings and so if we click on the gear right here notice how there's going to be a number of different options in here that you can adjust so these are all going to have to do with what's shown inside your scene so for example let's say that you wanted a little bit better performance you could bring your shadow quality down a little bit and so what that means is that means that it's not going to use quite as much processing power to generate your shadows your quality will be a little bit lower but your performance will be a little bit better so other things in here like anti-aliasing so if we do the anti-aliasing notice how if we look at like the corner right here so what the anti-aliasing is going to do is it's going to come in here and it's going to get rid of these jagged edges so if i click on this notice how this moves out this edge right here so if you do want better edges and less rough edges then you can turn the anti-aliasing on so exposure is going to be another important thing that's in here so you can turn on or off auto exposure so depending on what you want to do notice how if you turn auto exposure on and you feel like things are a little bit dark in your scene you can also use this ev compensation in order to bring those up so you can adjust those things in here in order to adjust the way this is going to look so there's some other things about your movement and other things like that that you can get into we're not going to worry too much about that for right now other than note that you can adjust your sensitivity and fly speed one other thing is notice if you check the box for high quality cosmos assets and you bring assets in from the chaos cosmos library what this is going to do is it's going to use the highest level of detail for those so you can use very high levels of detail when those are rendered out but it is going to take additional computer power in order to render those out so those are just options that you have in here now let's take a look at what happens when we make changes inside of sketchup so let's say for example that we want to apply some materials maybe from the v-ray material library right here so what i'm going to do and sorry i'm trying to fit this all on one page but what i'm going to do right here is let's say i wanted to apply a concrete material to these walls inside of sketchup so what i'm going to do is i'm going to select my wall object right here and we're going to click into the concrete and notice how there's options in here for different kinds of concrete well let's say that we wanted to use one of the simple concretes over here well you could just right click on this and click on the button to apply to selection you'll notice how when i make that change that change is not only reflected in sketchup it's also reflected inside of v-ray vision so the changes that you make inside of v-ray vision are going to be real-time this can be really helpful if you're doing things like looking at different materials and how they look inside your scene notice how i can just come in here and just apply the different concrete materials from this library really quickly in order to get different looks and so not only can you apply materials in real time using the built-in v-ray material library you can also use the chaos cosmos library so and i made a video about this which i will link to in the notes down below but let's say that you wanted a concrete or asphalt material from the chaos cosmos library what we're going to do is we're going to click on the cosmos button and that's going to pop up the cosmos browser and remember you can go in here and you can find things like vehicles and furniture and vegetation as well as materials and so let's say we wanted to apply an asphalt material to our ground right here well all we would have to do is go into our materials and i've already downloaded one so we're just going to bring that one in what we want to do is we want to click on this button right here and what that's going to do is that's going to import the asset from chaos cosmos or into your active materials in your scene now if i go into my materials manager notice how that asphalt gray right here is going to show up in that list so it's not contained inside of the v-ray material library that's built on your computer this was actually brought in from chaos cosmos but if i was to right click on this click on the button for apply to selection notice how that's going to apply that material to your ground right here as well as in your scene over here and we can use this to quickly apply the high quality materials from chaos cosmos into our scene so let's say for example that i wanted a ground material like this grass right here i'm just going to do the same thing i'm going to import that asset and then once i import it i'm going to go into my vray materials editor i'm going to find my grass and i'm going to apply it right here so we can use that in order to quickly apply the grass material to our scene as well and so let's say that we wanted to bring in not only materials but also context models right because high quality context models can be really important so let's say for example that we wanted to bring a car model in and place it right here so we're going to jump back i've already downloaded a car and i want to bring that into my scene and so i want you to notice what happens when we bring that into sketchup what happens inside of v-ray vision so if i was to take this car and click on the button right here if i was to click on this little green button notice how i can bring this car in and place it in my scene and so when i click notice how in addition to the showing up in sketchup this is also going to load inside of v-ray vision and if i look at this car right here and we may bump our exposure back down just a bit maybe something like this but notice how this car is getting brought in as a lightweight proxy model over here but then a detailed model inside of v-ray vision so what that means is that means that we can have a lightweight sketchup scene over here that we can explore in real time on the right hand side of our page so we can use this in order to really quickly create realistic renderings using context models and so we could also do this with the scatter function so we've got this green space over here well what i want to do is i want to scatter some objects in here using a chaos cosmos vegetation piece so we're going to go back into our 3d models i'm going to go to my downloaded 3d models and let's say i wanted to place a bunch of these purple willows in here like this so i'm just going to bring a purple willow in and i'm going to scale that down because that's going to come in way too big inside of my scene so i'm going to scale it down over here notice how the changes that i'm making on the left hand side are also being reflected over here but i'm going to take this i'm going to place it so that it's on the ground and so what i want to do is i want to come in here and i want to select this surface well then i want to click on the button for scatter over selection well what that's going to do is that's going to add a scatter modifier that you can find inside of the v-ray geometry section right here so notice how scatter is now associated with this surface right here what we want to do is we want to add guests to this and so in this case what i want to do is i want to go select the purple willow right here and then click into my scatter and click on the button for add guests and so when i click on the button for add guests what that's going to do is that's going to scatter this object based on these settings right here inside of my scene so notice how these purple willows are being scattered all over the surface well the cool thing about this is if we jump back into v-ray vision like this notice how those are all being scattered in here you can see them all in real time and so let's say that i was to adjust my density up so instead of one let's say i wanted this to be two and we might do this with more of like a grass material but um i'm gonna bump my my density up to two well notice how when i bump my density up these right here bumped up as well so you can also use the seed function to randomize where those objects are going to go and this is going to take just a second to refresh but notice how those changes are being reflected inside of v-ray vision and then i can also fly around i can look at them a little bit closer other things like that and we may want to check the box for high quality cosmos assets notice how when we do that it's going to reload the scene but those are going to get loaded in with more detail now inside your scene so if we zoom in and look at these you can see how they're going to be really high resolution and you can fly around and look at them in real time so you can actually see the effects of the changes that you're making let's go ahead and drop a couple trees in here real quick from the cosmos library so again it's really easy to do because all we have to do is just open up the cosmos library pick our tree and place it just like this all right so one cool feature that they added in v-ray 5.2 is let's say that you wanted to add grass to this surface right here well previously the v-ray fur implementation didn't really work here but what we can do now is we can add a v-ray fur object right here to this object what that's going to do is inside of your v-ray asset editor you're now going to have an object in here for fur well what you need to do is you need to make sure the word grass is in this name so let's say we wanted to call this fur underscore grass like this and hit the enter key what that's going to do is that's going to allow v-ray to recognize that this is supposed to be grass and it's going to render it in the scene now notice how that change hasn't been made in here what i found is you need to reload v-ray vision so if i just close it and open it up again then now there's going to be grass on that surface where we applied that v-ray fir so you can use this in order to create renderable grass in your real-time renderings really quickly so you can see how now your grass is being rendered out in this location so say you didn't want all these bushes and you just wanted to apply a grass to that surface that's an easy way to do that alright so just for a second let's talk about lighting so notice how in our scene right now it's a certain time of day with a certain shadows right but if you hold the shift key and click and drag your left mouse button notice how you can adjust both the height of the sun by dragging up and down as well as the direction of the sun by dragging left and right so you can fully control the direction of the sunlight in your scene so in addition to being able to adjust the artificial environment lighting if you're to drag this all the way down notice how this switches to a nice scene but you could also bring in artificial lights from v-ray's artificial light library so things like this sphere light and notice how these are going to update automatically inside v-ray vision as well so if you do want to do something with more like artificial lighting you can adjust that inside of your scene and it's going to adjust inside of v-ray vision all right so in addition we can also adjust the way that the overall scene looks using the color corrections option right here and so you've got an option here if you want more of a contrast look you can apply this aces curve option right here but you can also come in here and adjust things like your overall exposure as well as things like your contrast so the difference between your lights and darks notice how if i drag this to the left i'm getting more of a gray look the more i drag this to the right the more contrast i'm getting between those light and dark portions of my scene so you can also adjust the amount of color saturation that you have in here as well as your color temperature if you want this to be a warmer or a cooler image so those are going to give you different feels and what you might do is you might adjust these sliders just a bit and then save them so if you click on the save button you can save this in a folder as a vision color correction file so for this one i could say like warm colors and click on save well then if i was to reset this and i wanted to load that i would just go find that file i'll just load it and it's going to bring it in automatically so you can use that in order to save your different color corrections for use in the future all right so i've got my color correction selected now let's say we wanted to export an image so there's a button right here for output that's going to allow us to export an image and so we can either set this to be an image an image sequence or a video in this case we're just going to worry about the image we're going to set a location by clicking on the folder and then you can set your resolution to be either whatever the vision window is or from project in this case we want to go ahead and we want to leave this from the vision window notice if you wanted this to be higher resolution you could also set the size multiplier to make this a bigger image so in this case i'm going to go ahead and leave it at like 1.15 maybe something like that and i'm going to click on export what that's going to do is that's going to export this image to the folder you selected and you can open it just by clicking on it so you can use this in order to export this you can kind of play around with that a little bit too with your different settings exporting these images is really fast which is really cool alright so let's say we wanted to export an animation so let's say that i had really i'm just going to set up this scene right here and then let's say we wanted this to fly around over here so something like this right we'll make it very simple i'm just going to add an extra scene and then i'm also going to go into my scene manager real quick and i'm going to uncheck the box for include in animation so now my animation is literally just an animation between this view and this view right here well then what you need to do is first off you need to go into your v-ray asset editor under the settings right here and you want to check the little box here for animation like this and note that when you make that change you may have to restart v-ray vision but now if i click on this notice how there's an option for an image sequence or a video in this case we're going to do a video right here we're going to leave our camera type as standard we'll go ahead and we'll just call this video 1 and click on save and then we're going to leave it with the webm we'll leave the resolution mode so i may bump this up a little bit like this and so then we're just going to click on the button to export what that's going to do is that's going to come through and that's going to render out your uh still images for each one of the frames so for this four second long video and then it's going to stitch it together into a video that we can watch so we're going to let this work for a second then we'll come back and take a look at the result and so now if you go in that folder and double click on this you've got your rendered animation in here that you were able to create really quickly using v-ray vision and so remember you could also do things like saving your sun location so let's say you had your sun right here for your first scene and then you wanted your second scene let's say you wanted this to have the same camera view but like a different sun location like this so maybe something like this right you could update that scene so then what that would do is that would export a sun animation so we would do the same process as we did before but this time it would just be your sun location moving so you can animate different properties inside of sketchup as well and then export them to vision all right and then finally because i know this video is getting a little bit long but um you can also export a standalone application so basically what that means is you can click on this button right here to export this and we're just going to call this box house but you can click the save button and this will actually package everything up into an exe file that people can open up and they can actually fly around in it without actually having v-ray so we're going to let this work for just a second all right so what this did is just exported this as an exe file and if i double click on it and open it up what it's going to do is that's going to open up the standalone viewer that you can use to fly around this scene alright so you can see what this does is this standalone i've closed sketchup and everything else but this standalone viewer allows you to actually fly around this scene in 3d without actually having v-ray on your computer so i can go into like first-person mode like this i can also hold the shift key and adjust the shadows and change the sun location and other things like that as well so i think you can also export images from this so even if you're an external user and you want to export some still images or you want to adjust your exposure other things like that you can do that from inside of this tool so this can be a really great communication tool for sharing your different renderings from v-ray to external users so if you are interested in v-ray i will link to that on this page as well as a tutorial on chaos cosmos their online material library but leave a comment below let me know what you thought as always thank you so much for taking the time to watch this and i will catch you in the next video thanks
