3 Quick Tips for Better and Faster Redshift Renders in Cinema 4D | Greyscalegorilla

in today's video I'm gonna share with you my three favorite things that I've learned while watching the greyscale gorillas guide to redshift let's do it [Music] everybody it's Nick here from grayscale gorilla bringing you the tools training and tutorials to help make you a better motion designer now if you've been following along you may know that I have this new PC this great new rig and I've also been trying to learn red shift well it just so happens we have a guide to red shift at grayscale gorilla that I was able to start watching right away in fact it's called grayscale gorillas guide to red shift and it came at a perfect time for me because I was just switching over to red shift and I wanted to learn how to incorporate it into my renders I've learned quite a lot from it and if you've seen my renders lately on Instagram they've I at least I feel like my game has really stepped up now that I use a third-party renderer so with that let's head on in to cinema 4d and let me show you my three favorite things that I've learned while watching the grayscale gorillas guide to red shift all right here we are in cinema 4d and let's get started right away with the first tip and it's all about getting your clone colors to be represented inside of red shift you can see in the scene we have a bunch of clones happening and we're using fields in cinema 4d r22 Drive not only their position but also change their color you can see it's not being represented in the final render well let me show you how to set this up in red shift first thing you need to do is make sure you apply a red shift material to your cloner if you don't have a material already set up you can go to create red shift materials material and just drag this onto your cloner now once you do that you're gonna get something looks like this right you're not gonna get the colors of your scene so what you have to do next is double click go into your edit shader graph now in the grayscale gorillas guide the red shift they go into a ton of detail what all these nodes do and how to set up your own custom textures but I just wanted to show you how to get these colors in there for now and what you need is a data node now this is the color user data node in particular so all I did was type data in here and it found the one I wanted here your color user data drag this out into your shader graph and then the next thing you need to do is tell this data node what you're looking for so up in here there's an attribute name right over here you can choose mograph color that's what you want still not done yet it's not represented we need to tie this node into our redshift material and tell it what we want it to color now to do that all you have to do is go drag your out a little knob here just click and drag over to the blue section of your RS material and as soon as you let go all these properties are going to show up this means that you could pipe this color into practically anything in your material in our case we just want it in our diffuse color Channel so I'm going to click that I'm gonna close out of our material and it should update right away boom look at that so now any colors that we change in our clones anything we do with mograph and fields will now be represented in fact I have a second effector up here it's actually a field they call them so we have a second field that is coloring these clones this green color and you can see that that follows through as well so if we hit play you can see all this animation all the stuff that we're doing in our scene will now instantly be shown in our redshift material all right let's jump right into the second tip and this one's all about how to apply depth of field to your render I knew right away when I started playing with redshift that I was gonna throw depth of field on everything it looks amazing and in this render I wanted to show you how to set it up so what we have here we have a really simple mograph scene we turn off our render just we could see the animation we have a really simple mograph scene and we also have this material that is on here from the everyday material collection and this is I think it's frosted glass and it just looks beautiful but I figured a little bit or maybe a lot of depth of field will really make this thing shine so how do you add it well you want to make sure you use this on the camera that you want to do your final render on in this case I have a bunch of cameras in my scene some of them to animate between I'm using gorilla cam here to do the targeting so I'm gonna add it to our gorilla cam and all you have to do is select the camera you want to add it to you go to tags and you go to your redshift tags and add a redshift camera now the next thing you want to do is make sure that this tag is selected go to the bokeh tab over here and turn on enabled and after that to control the blurriness the amount of blur to your depth of field you can do that right here with this slider the COC radius this stands for a circle of confusion I learned that from watching the training and you can crank this thing up and get boom that sexy redshift blur right away in your scene so I think it could go pretty far with this effect I like the idea that these letters are kind of unreadable at first and then as they resolve they get nice and clear so that's you know you can adjust all this stuff as you go and you can see how fast the depth of field renders as well I've just been loving this feature inside of it and I wanted to make sure that you knew how to set up depth of field alright let's jump right into the third and final tip and this one's all about render settings and in particular how to set up your scene for a grain-free render and in the least amount of time now any new render handle samples and and render settings much differently and redshift has their own way of doing things in particular they use samples in almost everything in this case we're looking at the dome light here and you can see that there's this sample slider now this exists on practically every light every material inside of redshift now in the past when I just first started playing with redshift I thought the way to clean up your scene was to go into redshift and start cranking these numbers way up and what I learned by watching the redshift training and they go into a lot more detail in in the actual training but what I learned is you want to dial these up last and you want to start to turn up your other samples in other parts of of cinema so in this case we're gonna start to turn up our light samples essentially you know cranking more light data into the scene and and that will start to clean up our render without having to turn up our final brute-force render so let me show you what I mean let's use a different camera angle for this I'm gonna use our overhead camera let's go ahead and zoom in here and start to look at some of this grain that's happening in this render so let's go to original size I'm gonna highlight this and go to a hundred percent I'm gonna use the alt button to pan around here I'm gonna throw a bunch of tips at you for this one and then we're going to shift drag to make a little window that I only want to render a part of this will help us look at just this one little part and start to dial in settings and as this cleans up we can compare it to where it was out out here okay so what else can we do to get ready here's another bonus tip this bucket window will allow us to see the final render right so with this on you're gonna see this is the final render quality and you can see we have a ton of grain here especially in this shadow let me move this up and show you check out all that grain well the first thing we're gonna do to try to clean up any lighting grain is to turn up the samples on our light now the other tip is to try to do these samples in multiples of two so wherever it is now try to go up by two let's go to 64 and you can see it's gonna recalculate and that's not nearly enough so something to keep in mind and and this was interesting to learn you can actually crank these up really high I'm gonna go up to 512 that happens to be a multiple as well and now you can see we're cleaning up this grain a ton compare this to over here and you could do this again 1024 it is let's see boom and you can see the renter is getting slower but much more clear and look at that now this is much more clear than over here now once this is set up you want to go into your render settings and then start to turn these numbers up and that's really the difference that's really the tip I'm trying to share with you guys is don't crank these up first turn up your samples in your lights turn up for your samples in your global illumination here's the brute force GI samples that we're using maybe we need to turn up some of these as well let's go to 512 it might be a little bit overkill but let's see the difference and it's taking a little bit longer but again less grain in our shadows look at how clean that is compared to that hope you could see that on your monitor but this is really the tip constant your samples where they matter and and that's like a quote from the training that I got and it really does hold true it speeds up your render if you put them up front now if you want more detail about all the settings and all the other ways you can be more efficient with your rendering definitely check out the redshift guide but I wanted to share with you this tip because I wanted you to think about samples the right way to begin with thanks everybody and don't forget if you're looking to add redshift to your 3d workflow don't forget to check out our grayscale Gorillaz guide to redshift I've been having a ton of fun watching and learning it so please if you're learning redshift please check out our training and with that I hope to see you in another video really soon bye
