5 Tips For Better Renders in Blender 3D // How To Use Backplates?!

[Music] in this video I'm going to share with you five very important tips to make your back plate renders in blender into the next step let's start [Music] so I opened a new file here I just bring my car model here this is the muscle car that I built before it even has some mistakes as you see it's not a finished model but if you use more finished model more high quality models the renders will be also affected in previous videos we used some hdris and we know how to do it but in this video I want to use backplate images but the tip number one is to use the same hdri and the back plate from the same source so this way the reflections and the background will match in a better way and also the angle is very important so I will go to render View it's a new file so there's nothing on this file no hdri yet so I go to my render engine I will go to Cycles and I will pick my GPU so I go to my Shader editor here below I go to the world option on the Shader editor and here I'm going to add an environment to do that shift a texture environment texture and I picked this hdri by the way today's sponsor is synbox 360 and we will talk about them very soon so I took my hdri I connected to the background as we see already we have the environment and we need also the back plate to activate the back plate I go to hit number pad 0 I hit the number pet zero I pick my camera and when I pick the camera we have this camera options here I turn on the background images add an image open and I'm gonna pick the back plate image from the same hdri so I pick an angle like this this is the back plane so now what I'm gonna do is I'll just move the camera around in the camera view I will go to my view turn on the camera to view and I kind of match my camera angle with the car here very important thing is the camera lens like if you if you have very wide angle lens on the image or on the camera they need to match to see this we can go to right click to the image and see the properties on the details we can see some options for example the resolution which will be also necessary soon but what I want to learn is the focal length and here it says 55 millimeter so on my camera in blender I will try to match it something similar by default we have 50 so it's quite similar but let's do it 55. and then I try to match more or less the car angle to fit this background if you see it's a little bit more pale it looks not totally full opacity and it's here I can just drag this slider to one so this way I can see the full image on the background so let's say my car fits a bit like that or this is too much front of the car so I'm just gonna change the image maybe I will pick the first one and rotate the car a little bit maybe something like that now we need to match the angle of the hdri with the back plate for this I'm going to lower the opacity again so I can see what's happening also on the back of the car like on the hdri so to rotate the hdri I'm gonna pick on the Shader editor the image texture the environment texture Ctrl t with the Wrangler node add-on is turned on so if I zoom out now I can see the background as well and here on the rotation I will just rotate until I get a similar view with the back plate and I see that the wall the trees and this side wall on the road is more the same angle so I will keep it like this so the reflection is also now correct on the car and I can again move the opacity to full and be sure about my angle of the car maybe a little bit like this is better so the tip number two is adding a ground Shadow because on the back plate we don't have the Shadow the car itself has some Shadows but the car's shadow on the ground is not visible so I'm gonna add a plane basically scale it up let's move it like kind of matching with the tires a little bit even cropping scale it up it doesn't have to be huge the goal is to more or less catch the shadow area I go back to my camera view right now as you see we have the shadow but also we lose we crop the image from the background to avoid this it's very simple I go to this object properties in the Cycles Render engine and to visibility and check the box Shadow catcher so now it still looks a little bit awkward the reason of that is the back plate is not on the front let me show you what I mean if I go to my camera settings again the back plate is depth is the back so if I put it on the front it's in front of everything if I put it at the back it's on the back of everything so the ground plane is kinda intersecting with it but it's totally fine if I rotate my camera you can see that we only see the shadow behind the car we don't see the plane we just created it's only catching the shadow basically so I go back to my view here the important part the tricky part is the reflections of this ground plane is on the car white Reflections on the side of the car and it cannot happening on this environment right so to avoid this I will go back to my plane again I will for now remove the shadow catcher I want to see what's happening with this plane and I want to reflect the environment more it's a very simple thing I will go to my object on the Shader editor I assign a new material shift a takes your image texture and then rather than opening or adding a new one I will pick here the image we already have for the background for the back plate okay then I add this color to the base color and I have my back plate also on the floor now but I want only the ground I kind of want this ground to reflect on the side of the car so I just picked the texture Ctrl T and maybe scale it a little bit to scale it by the way you can just hold alt and pick all of them and you can just drag your mouse so I just hold alt and just pick them all and started sliding something like that is enough for me because now I will also move it on other axis Slowly by holding shift to move very slowly somewhere like that so now when I look at from the camera I see the ground here more or less right so the reflection of this will be also kind of like the reflection of the ground after doing this I will go to my object properties again when the ground plane is selected and turn on the shadow catcher so now we don't see a totally white reflection of the Shadow catcher we will see the texture of the environment as well so now it's time for the tip number three and tip number three is using unique back plates and unique hdris because when you grab the first image you can find online for free you might look like also the others in your portfolio this work can look like very ordinary and people can't even know I know this background I also used it and it becomes too familiar and it lose the effect of the sponge effects this interestingness maybe so to do that I want to say thank you to today's sponsors inbox 360. it is a platform you can find high quality hdris and backplate images to use on your personal and Commercial projects I also downloaded this background and the hdri from their website from SIM Box 360 this way it has more Unique Look than any random Project online and by using the chord background pipe you can get 25 discount on any product in cinebox 360. all right the tip number four is matching the resolution of your render with the back plate image so I go to my render tab as you see by default Is 1920 to 1080p I go to my image and the properties and here I can see on the details what's the resolution is 2002 one and a half thousand pixels so I type it also on my camera resolutions this way the proportions of my render the dimensions of my render will match with the background with the back plate and I will go to my camera settings and make the opacity full and for now I'm gonna just hide the background for the shadow catcher sorry and I want to be sure about the angle I think this should be fine and then the tip number five is the export settings of our render now first thing what I want to do is on the render settings I will go to film and check the box transparent so we will not see the hdri anymore as I see we should have done it before because this way we got rid of this annoying gray intersection let's say let me show you again if I unbox the transparent we see this gray Shadow catcher kinda intersecting with them so if I just turn on the transparent we got rid of the hdri because we don't want it to be visible on the render and backplate and the shadow everything is matching perfectly so now I'm gonna render this but the important thing on the render settings please be sure that you pick PNG and rgba settings this way we will have the alpha so the background will not be visible but we will have the Shadow and we will have the car so on post production we will match them let's hit render foreign ER is done so I'm going to save my render and I just opened both of them on Photoshop this is my render and this is the background so simply I will just hit Ctrl a to pick everything from my render Ctrl C and Ctrl V so as you see it just snapped on the background and I can always move around I can still scale it down scale it up but by default because of our resolution of the render and the resolution of the background match it automatically match just like on the render that I wanted so the rest is post production I'm gonna quickly edit some colors and some levels and brightness and this type of things and basically that's it first thing I want to do is adding blur actually I will just duplicate this background go to filter blur and the lens blur I add something very small just a little bit background blur and then hit OK but I don't want this foregrounds to be blurred as well so I will just get a very big eraser and just erase the front area so this way the blur is on the background but not on the foreground I will do something similar with the car I will hit this Ctrl J but it also duplicated the shadow so maybe we don't need to do it at this stage or let's do it I'll just hit Ctrl J filter lens puller I added same type of blur and with my Eraser I just erase the front of the car and also the shadow because I don't want it to be super dark so also on the back of the car we have now a little bit blur so then I will hold shift Ctrl alt and E to merge everything in a one new layer then Ctrl J to duplicate because I want to keep the original in case I want to go back and then camera roll filter in camera raw filter we have a lot of options and for example on the basic I want to increase the contrast a little bit more but I will also increase the Shadows a little bit more because the car is a little bit too dark maybe highlights let's see maybe it's getting too bright so I can turn on the D Haze to make bring back sharp darks again a bit more clarity Maybe texture texture is always nice I think for the images and for the colors I don't know this is if it's more color grading stuff now so I don't know if you are interested in but these are the quick tips that I like to do on the saturation for example I can pick this eye icon this picker icon I can go to my greens and I can desaturate them a little bit adds a little bit more touch a little bit more personality to image in my opinion or we can pick the orange and also look desaturated luminance so we can pick the greens the specific color is darker or lighter it's up to us totally and I'm gonna add some effects like a little bit of grain to the image and a little bit of vignette so the center of the image will be more on the focus the rest will get a little bit of this Darkness if you see the before after this is before this is after we added more crispy details and a bit more personality to the image then I just duplicate it again I go to levels and make it make everything a bit darker like this and then with a big eraser again I'm gonna just show where the light is coming from because the light is coming from the left top as you see so here I want to emphasize this Darkness a little bit more if you see before and after we basically added a little bit of Darkness so what we basically did is number one using the same hdri and the back plate and the same angle number two we use the shallow catcher on the ground plane and we added also image texture to it to not have the flat reflection on the car itself number three I use the hdri and the back plate from the Sim Box 360 so I have more unique and more personalized more interesting output on my renders number four we picked the same resolution for the render from the back plate image so they match on the post production and number five we picked on the render export settings rgba RGB Alpha to have the background removed from our render so we can we have more flexibilities for the Post production as a bonus I can say we did some color grading but it's itself and other topics so I didn't want to go much easier details in this video I hope you enjoyed if you liked the video please show it on the
