Vray for Rhino Tutorial _ global settings

hello and welcome to my beer a 3/4 Rhino six settings tutorial this tutorial is intended to go through the general global settings of beer a three to talk about what they mean and get you set up on some settings that work well for architectural projects so it's important to know that these settings are specifically designed for beer a three and Rhino six they do not work the same as old beer a two and/or beer a three for Rhino five so keep that in mind this is the latest build of both programs so to get started let's go to the asset editor so and your beer a icons here it's this v-ray logo if you click on that you can see we have the v-ray toolbar the default here is this beer wheel which is all your settings so these are all of your global settings so we'll run through these kind of what they mean and why they're important the next icon over are your few a geometries which we'll get to the later tutorial v-ray lights we'll get to this to turret in a later tutorial where we discuss scene lighting and then finally the materials and this is where you create materials if you pull out this bar in the lab there's all these preset materials but and we'll get to the material tutorial as well where we cover all those so for now let's just look at our our global settings so the default settings are shown here I'm going to explain a few and then we're gonna add us to get them set up before I think works best for more architectural rendering the array is again as a program was used by many professions to render and many different styles so what I've tried to develop is settings that work very well for architecture specifically and also that do a good job about managing and quality because beer a can make perfect photorealistic images but it takes a long time and potentially multiple computers so for the average architect working on a fairly decent computer these settings seem to work well so let's jump in so first I'm going to turn off the progressive toggle here below that is quality so this is gonna have a great effect on your time overall but is a great way to be able to test things at a low quality and then bump it up to high once you feel confident that all your materials and your lighting is correct and you know that it's ready to get the final output so camera we're going to go over that for now we'll come to that in a later more advanced tutorial the default settings are okay for this so I render output this is extremely important the default is set to this 800 by 450 so that's 800 pixels wide by 450 so what we'd like to do is come down to this aspect ratio which is set to a standard 60 by 9 and so I don't want us to see mine I'm actually when I drop down and change this to match my viewport so I think it's more important to match what you're seeing in your Rhino window so now it's going to match the proportions of everything I see here and when I hit render if I see it here it'll come up in the view so that said if I change something here if I wanted to make it bigger a thousand pixels wide I put type in a thousand here and it automatically changes my heights so because it's keeping the proportions of my view frame save it image is super important if I turn this toggle on what that'll do is as soon as the rendering is done it'll automatically save it to the file path which you can just put in here and put it wherever you'd like to save it this is really great when you do a big rendering or you let something overnight and the rendering finishes but then your computer decides to do updates and closes it and you lose the whole thing this will solve that by just saving it immediately it's happened to be a lot of times so it's been a lifesaver environment again this is something once we start setting up our scene lining will get more detail here material override is a great tool for quickly if I turn this toggle on essentially what I'll do is we'll override all of our materials so if I have a concrete wall or brick siding it's a metal or what in this class it'll turn everything into like a nice light red here's a sort of a clay rendering well I can come in and and focus more on getting my lighting and my scene lighting getting all my shadows things like that that I don't need to look at the material for I can very quickly set up while this is all over written I can also change it to a specific material right now there's nothing to choose from cuz I don't have any material is made but just to kind of standard light gray is usually fine for your override and it speeds things up so you can focus on one thing at a time it's essential and be ready to not be trying to end too many things at once because one it'll take forever in to all the variables affect each other so it's nice to kind of limit your variables and do one thing at a time to fine-tune your rendering to where you want it so over here all of these settings are sort of our render engine settings and right now I want to focus on the global illumination render engines so I want my primary raised the default is brute force I'm gonna actually change this to the irradiance map and for my secondary rays I'm going to change this to brute force so these are actually going to give me setting a look that I think is a nice crisp look for architecture projects and will not totally blow it up is from a time standpoint another thing want to do is just turn the ambient occlusion on again I don't need to don't want to get into the weeds about what all of these mean concessional standpoint mostly because it's you know it gets to a technical level of really understanding you know light physics and computer science that I don't think is totally necessary but I've kind of done my own personal testing and I sort of landed on this combo is is the best way to get an output last thing I want to talk about are the render elements so if I drop down here it says add render elements I can if I just click here this list will pop up and these are all the different types of output so I think it's so one of the things I always like to put here is my material ID because beyond my rendering giving me just the finished product it'll also give me a material ID meaning that every material I have will be rendered in a solid block color so it almost becomes a paint-by-numbers output that comes with your rendering and it makes selection and Photoshop much easier so I just keep that selected at a later tutorial we'll come back to that and see how how that affected it and why it's important so before we are finished with kind of running through all these I just want to talk esepcially about the difference between the dimensions and the quality so dimensions are gonna be more important for your final outputs meeting that if you're going to be printing this on large format boards you're gonna want to knock this up into the five to six thousand range to make sure your dpi is correct and you don't lose quality whereas the quality here is going to be the settings that in which your renders so if you see if I have this on low if I change this to medium and high you can see it's reducing my noise limit it's changing the some of the settings in my irradiance map settings this is going to be basically adding more detail and more accurate light bouncing things like that reflections are gonna look better so the quality is gonna is gonna do what it says and it affects the quality of the image but it's gonna work and with the sides so low quality and low size would be fast when you get this high in this high gets very fast occasionally if you're only going to be projecting this or maybe an 11 by 17 printout you can get away with moving up this up high keeping this as small it's 2,000 to keep your time there but these are going to be working tandem for your timing and while the size is sort of a linear and how much time it adds meeting if it's 1,000 wide and you can bump it up to 2,000 it'll take about twice as long the quality settings when this is goes from low to high the medium is more of an exponential time increase so if you're low render settings taking 10 minutes and the mediums taking an hour high could take 3 hours so keep that in mind when you're running through these and so that you're not wasting time with your settings so now that we have these set up these will be locked into our Rhino model they won't change if I close out of here I come here do some work say that open it a week later on a different computer go to my asset editor all of these settings will be saved that said you can always load settings as well so if you get if you have these in here and you like them you can save them so you can save them as you know starter or I have some dusk and perfect day some various settings that I've done over the years you can save those and then when you open up a new project you can just click here to load your render settings and you can just click on your setting click open and it'll open it up and all the things will change here you can see that various settings with some minor tweaks and they all come back in even down to the last time I use this setting I had 4500 image width and I was rendering a hive its most been a final product so that's the way to set those up also to save them and load them into new files if you need to and that'll be it for today thanks
