Getting Started Rendering in VRAY (EP 1) - BEGINNERS START HERE!

what's up guys Justin here with the rendering essentials comm back with another Sketchup and v-ray tutorial so in this video this is the kick off video for a series on how to get started using v-ray to create photorealistic renderings in your models so I'm gonna be taking you step by step through all the tools and functions contained in v-ray so if you're looking for the full playlist make sure you check out the links in the notes down below for the full playlist now let's go ahead and just jump into it alright so a couple things the first thing is we're gonna keep this fairly simple so that we can keep it easy to understand for a lot of these concepts there will be more advanced videos coming later but I wanted to give you kind of an overview of what v-ray for Sketchup looks like and how to use it so when you first install v-ray for Sketchup you need to make sure that you have it enabled and you can do do that by going up to window extension manager and you're just gonna find the option for v-ray for Sketchup make sure that's showing enabled and if it wasn't click on click on the button and then click apply changes in order to enable that and so when you do that what you should see is you should see three different menus or three different toolbars and note that this may look a little bit different depending on your version um so my version of v-ray is we're a three point six this may look a little bit different but the tools in general stay the same across the different versions and so we have these three different toolbars and these are how we can affect or we can find our different things inside of v-ray so the first is the one you're gonna do the most in which is the v-ray for Sketchup toolbar and so that's going to contain things like your asset editor them things like turning on and off your different kinds of renders I'm doing some other things as well but generally you're gonna do most of your work inside the asset editor unless you're working with lighting or a couple other things so we'll get into that in a second the other two toolbars the lights toolbar is designed to do just sort of sounds like it lets you access all of the different kinds of lights in v-ray so like for example if you wanted to bring in a sphere light you would click on this come click in your model and then you would click to set your radius and that's how you would bring a light into your model and we'll talk about we'll talk more about lighting in a future video and then the last one allows you to create an infinite plane work with different proxies and other things like that as well as adding fur and grass and so we will get into all of those in a future video as well for now I want to focus on the v-ray for Sketchup toolbar and so the first thing I'm going to click on is I'm going to click on the asset editor and so when you bring up the asset editor it's gonna look something like this it may look a little bit different because you have these different toolbars in here or these different tabs and these tabs do different things like for example this tab right here this allows you to access and edit different materials and so that's going to affect the way different materials look inside your rendering and you can see how right now this is basically just showing a list of the materials that's contained in your model and so in this case there's two little arrows over here that you can click in order to access different options like for example if you click the left arrow you can access the v-ray material library this is where you can access the different materials contained inside of v-ray so and that's one thing to know is there's different kinds of materials so there's materials that are contained within Sketchup and so when you apply materials inside a Sketchup things like this concrete scored for example if you zoom in to them really close they're fairly low resolution and what that means is if you ever run a rendering using something like this material maybe this one or let's go to probably one of the wooden materials like this wood floor material you can see how it's super low resolution and so if I was to come in here and do an interactive render just to get an idea of what this would look like you can see how it's not very realistic just because of the resolution and the quality of the texture and so a lot of the time what you're going to end up doing and I'm gonna pull this off to the side for a second is you're gonna select one of V Ray's materials or you're gonna create your own because if we pick one of these like let's say we were to pick like this wood veneer material so we have this object selected and we can right click and we can either add it to scene or apply it to our selection when we do that that material gets applied inside of v-ray it also gets added inside your Sketchup model so you can actually find that material and you can edit that so you can adjust different things like the size for example like how often this texture is getting tiled things like that but if you zoom in on this like really close and we'll go ahead and zoom in fairly close you can see how this is much more high resolution and high quality and so if you come over here and you look inside of v-ray or inside your interactive render that we're running you can see how this is a much more detailed image than what we had before with this old material which looked like that looked like this so you can see how there's a huge difference between the two different material types and the quality of the rendering that they can produce so more about the material library later but just know there are preset materials over here with everything kind of set up that are gonna look really good and the other thing I want to talk about is on this right hand side there's options in here to edit all of the different things associated with these materials so the diffuse map is the actual image that's applied to create this material so there's other things in here as well so things like reflections and reflection maps and refraction all this is where you're gonna edit the way that things look so there's things down below or you can apply different maps to make things look bumpy which makes them more realistic so when we zoom in on our interactive render here you can see how this would looks really bumpy that's because there's a bump map being applied to that which makes this look a certain way we'll talk more about that in the future but just know that all of the different things that you're going to edit having to do with your materials are going to be contained in here so we'll go ahead and make this a little bit smaller the next tab is the lighting tab and so the lighting tab is where you're going to be able to make adjustments to the lighting in you're rendering and so first thing I'm gonna do is I'm gonna go ahead and make this a little bit bigger I'm just adjusting this material so it looks a bit more realistic so now let's take a look at our lighting section so the lighting section is where you're going to be able to edit all of the different lighting that's happening inside of v-ray and so if you click on this right now you can see how this is showing two different lights it's showing the sunlight and it's showing the v-ray sphere light that we created earlier as an example so that that's kind of maintained in here even though I deleted it out of the model but it's still in here because it gets created as a component inside of Sketchup so if I was to go into my component section for example and it's a little bit of a tangent but if I click on in model you can see how I can still find this for your light that I created and bring it back in so the definition of this light was in here even though the actual light itself got erased out and so you can see how you can edit different things about these lights like for example if I wanted this light to be a lot brighter you can see how I can adjust the power of this light by typing a value in here and you can see how as I do this this this light is reflecting more because it's becoming brighter and for example you can also turn things on and off by clicking on these little buttons right here so if I wanted all of my lighting to just come from that sphere light and not have the sunlight running anymore I could do that and so when we do this if you click on this little right arrow button there's other things that you can adjust about your lighting you can adjust things like your color or other things like that in order to really kind of change the way that that lighting is gonna look you can also adjust things like if the light itself is visible or invisible and so a lot of the time what you end up doing or something like this and I'm gonna go ahead and hide this is let's say that you were in a room or something like that and you needed a light to kind of backfill everything so let's say that I wanted a light and why don't I move some of this stuff out of the way let's say that I wanted to create a light in here to kind of fill in that background what I could do is I could create a rectangle light like this and I could stand it up and you can use this to kind of like backfill light in while turning your lights invisible so that they don't actually show up in your rendering so a lot of the time you want this extra light that's going to be coming off of this but you don't necessarily want to see the thing itself so you can adjust things like that inside of the lighting section of v-ray so all your lights are going to be edited in here your geometry a lot of the time what's gonna be associated with your geometries if you do something like v-ray grass so let's say for example that I was to draw a rectangle here we'll go ahead and group it and then we'll click on this button for v-ray fur so v-ray fur and I'm gonna go back and turn my light back or my son back on so v-ray fur allows you to create stuff like grass inside of your models and so this is where you're gonna be editing able to edit different things like this there's also things called proxies which are lighter weight geometry that get brought in that don't slow down Sketchup but still allow view rate - uh they still are out allow v-ray to render really detailed things we'll talk about those in a future video as well but this is where you're gonna adjust things like this and so like for example if you were to apply a grass material in here you can adjust things like that inside of the materials section so things like the thickness or how much grass is being produced you can see how I can adjust the slider in order to adjust all of those things inside of Irae so that's where you're gonna affect your v-ray geometry this last section is where you're gonna be able to change things like if you're using your CPU or your GPU so your CPU of your computer or your graphics card in order to do the heavy lifting of the rendering you're gonna be able to adjust things like that in there you're gonna be able to adjust things like your exposure so you can see how when I adjust my exposure my rendering down here gets brighter so you're gonna adjust all those different camera settings and things that have to do with the way the overall rendering looks down in here and you know finally this section over here is going to be really important because this is where you're going to be able to do your actual rendering itself so there's a couple different kinds of rendering contained inside of v-ray and specifically what I want to talk about is the first three options so the first option is a good old static render so this render you just click the play button and it goes through and it just renders this as you go so you can see how this is going through and this is probably the most detailed render that you're going to be able to create is using a static render but it's going to take a lot longer and also as you make changes those aren't going to update however the second option which is the one we were using before and one thing to know is so only the only the static render the first option is gonna allow you the option between CPU and GPU you'll notice if you pick the second option which is the interactive render which adjusts as we go that's not going to give you the option to do that with your GPU itself and so that second option that we just clicked on that's gonna be for an interactive render and so what that's gonna do is that's gonna that's going to basically update your rendering as you move around inside of this model and so what that's going to do is that's going to update you're rendering as you create new geometry and other things like that so like for example as I push pull this up and I create this object you can see how this is updating as we go if I was to let's say apply like a glass material or something like that you can see how this is going to update as we go because it's interactive and so the trade-offs with this one is this is really good for previewing your scene and seeing what things are gonna look like so it it updates with you ooh that's horrible so it updates with you and it's really good for kind of framing your scene seeing what different materials are gonna look like your renderings look fairly good with your bump maps and other things but it's not gonna be the most detailed render in the world that's kind of the trade-off with the interactive render is it's less detailed but it's a lot faster and then the last option that I just want to mention for just a second is the option for render with v-ray cloud and so what that does is that's gonna allow you to upload that to the cloud and they will do the rendering off-site with their more powerful computers is a great option if you don't have a very good computer and you want this to happen off-site I believe there's an additional cost associated with that but that is definitely an option as well that's probably gonna be a lot faster and so in order to save on time I don't want to get too far into the different options inside of your frame buffer the frame buffer is basically a view showing what your rendering is going to look like so there's different things where you can adjust different channels or you can see different channels and other things like that your alpha Channel lots of other things I don't wanna get too far into that right now just know that these options are in here and there's other things that you can adjust as well and then the last thing I want to do really quick is just give you kind of an overview of the way rendering works so basically what rendering does is rendering simulates light inside a model so it simulates lighting and it simulates the way that light is going to behave inside of a model so for example if I was to create or you know what this is probably a good enough example um so like for example if I was to create a sphere like this one and we'll just use the follow me tool in order to create the sphere so if I was to create a sphere like this one and let's just kind of take a look at that inside of our interactive render so if I create a sphere and we have a light up in the sky what's gonna happen is lighting is gonna come inside this model from wherever your light sources just like it will in real life if and what v-ray is gonna do is that's gonna calculate what that light is going to do based on a material and so the way that rendering works is you set up your materials to effect the light a certain way and if you set them up right things look realistic so like for example right now because we have the sunlight turned on we have light coming down and this is casting a shadow onto this face and one thing to know is if you adjust you'll notice that those shadows are tied with the sunlight to Sketchup Sun so you can see how as I adjust Sketchup Sun this way and I make things either earlier in the day or later in the day that the shadows are adjusting along with this so this is actually simulating a real Sun inside of the sky and it's also simulating what those materials are gonna do when that Sun is cast on them so the other thing is we're really the two biggest things inside of rendering are lighting and materials and so the other thing that this is doing is this is simulating the way that the Sun is going to react or the way the light is going to react when it hits different materials that's what all of these different channels and everything else are are things telling v-ray how the light should react or respond and so in this case let's go ahead and turn off our Sun for just a second and we've got our we've got our rectangle light we'll go ahead and make that not invisible just for the sake of what we're doing here we're also going to make it a lot brighter so I'm gonna brighten this up to something like a hundred and I'm also going to scale it out just a little bit and so you can see how now with the lighting coming off of this light right here it's actually reflecting off of this wood material that's because it knows that wood is a reflective material has a certain amount of glossiness to it and so the lighting bounces off of this and different materials react to that in different ways so if I was to take a different material like let's say we were to pull some kind of simple concrete material and apply it to this you'll notice that the way the light bounces off of this and the shininess and everything else is different depending on what that material is you're not getting nearly as much shine off of this material as you were off of the wood material so if you were to get more of a tile material you see how you get more reflection in here so and also because this is using a map it's simulating the little the little depressions inside the tile as well so you can see how that's affecting the way that your light looks to and so this does the same thing with glass material so you can see how if I kind of look at the way this glass cylinder works its refract refracting this light it's simulating the way that the light would get bent as it goes through this object so that's how realistic materials are created inside of v-ray and we'll talk about all of those different things as we move further along into this playlist so make sure you check out the links and the notes down below I'm gonna link to the rest of this playlist for the kind of a start to finish tutorial series on v-ray leave a
