What's happening ladies and gentlemen, this is Minh from Architecture Inspirations. Today I'm going to show you some tips and tricks for interior rendering using Vray 3.4 for Sketchup. Let's get started. Nothing is worse than spending hours and hours on doing a rendering and then realizing that it was a bad design. So the first thing that I usually do is go find some inspirations to help me achieve a better concept. Here are some of the resources that I use to do my research. Houzz and Pinterest are the two sites that I use the most because they make it easy to create your own collection or ideabook. For example, to look for inspirations on Houzz, just go to the Photos section, and search for what you want. In this case, I’m looking for some inspirations for a Home Office design so I can just click here. This will search up all the home office photos, and when I find one that I like, I can Save that image to my ideabook. Similarly on pinterest, you can search it and then pin it to the appropriate Pinterest board. What often differs a good model from a bad model is the quality of 3D components, For Sketchup, there's no better place to find 3D models than the 3D warehouse. You can download models from the website or use the 3D warehouse tool to search directly from Sketchup. If you take your time, you can find some amazing models on this site, whether it be furniture, decorations, plants, or even 3D people. If you like to get access to these collections, follow this link to go to my profile and click on collections. If you cannot find what you want from the 3dwarehouse, you can always model your own object from inspirations like I did here in this previous video. When importing objects into your scene, be mindful of the scale because if the object is too big or too small, it can make the rendering look unrealistic So just make sure you do tons of research to confirm that your objects are at the correct scale. You can either do this by simply doing a good search. Or if you know the name of the product like I know this lamp is made by IKEA, then I can search it up and look for the its actual dimensions. Then just go back to Sketchup and scale it to the appropriate size. It doesn’t have to be exact either, but just make sure it's close enough to be realistic. Sometimes the only difference between a boring rendering and an interesting one is the materials. In the past, I've always used any material that I can find. whether it be from Google or just some random website But recently, I realized what a big difference it makes when using high quality materials. There are two main differences between high quality and low quality materials. The first one is resolution, the bigger the resolution, the better the material look up close. Which means close up shots will look amazing. The other difference is that premium material comes with different maps to make your material looks more realistic when rendered. I did a whole video on this so if you have not checked it out yet, I will link it up right here. So where can you get these premium materials? Well there's actually multiple websites out there. But one that I’m currently using is Poliigon.com. They have a huge array of materials with a new collection coming out every month. It costs money of course, that's why it's called premium but there are also free materials that you can download to try it out and see if it’s worth it. I’ve been using Poliigon for a while now, and trust me, it’s definitely worth it. It seems like a lot of people like to use wide angle shots to capture everything in the scene. It’s understandable, because they spent hours and hours on modeling the whole room so they want to show off everything. However, wide angle shots can often lead to a bad composition where viewers don’t know what to focus on. If that’s the case, consider using a tighter frame to compose your scene. For example, instead of using a landscape mode for this rendering, I’ve decided to use a 4 by 5 portrait mode to zoom in on a portion of the room. To do that, first open up the asset editor and go to the settings tab. Now expand the render output and turn on safe frame, then change the aspect ratio to 4 by 5 portrait mode. When you do this, make sure you pay attention to the field of view. If it’s too wide then it’d get distorted and take away the realism. To fix that, go to camera, field of view and you will see in the bottom right corner the current Field of View. It’s around 75 degree right now, which is super unrealistic I can easily change it by typing four, zero then enter to change it to a more realistic field of view of 40 degrees. There you go, now adjust the camera until you get what you want. Adding lights to the model is not the only way to brighten up the scene. You can also use the camera settings. For example, you can see that I have multiple lights in this model but when I start to render, it still looks pretty dark. Instead of adjusting existing lights, I am going to use the camera settings to brighten up the image. First expand the camera rollout and go down to Exposure Value. Adjusting this value will affect the camera’s sensitivity to light. Higher value results in a darker image, and lower value results in a brighter image. Alternatively, you can click here to go to the advanced settings, where you will see 3 parameters which are very similar to the settings of a real camera. If that’s too complicated for you, just remember this. A higher value here results in a brighter image. But a higher value here and here will darken the image. For example, this is the default setting of the camera. I’m going to keep the ISO number the same and only decrease the Aperture and Shutter speed for a brighter rendering. There we go, that’s better Before you render, I'd recommend adding some render elements to your final output. You can do that by first going to the settings tab. Click on this right arrow to open up the advanced options. Now expand the Render Elements rollout, click on this box and search for Denoiser. A denoiser render element will help reduce noise in your rendering. You can control the strength and radius using these presets here. Keep in mind that if the denoiser is too strong, you might start to lose details in your rendering similar to this. Another element that I’m going to add is the Material ID. This is a very useful image that serves as a selection tool which will help speed up your process in post-production. Once you’ve added all your elements, start the render and when it’s finished, you can view all the render elements with this drop down box here. Since we have the vray frame buffer window open, this takes me to number 8. For those of you who do not have Photoshop or other image editing software, you can use the VFB window to edit your image. Just click this button here to bring up the correction controls. There, you will see a number of settings that you can use. I will start with the exposure settings and adjust these sliders to make the image a little brighter. Then I’m going to use the color balance to add more of a blue tint to the image to give it more personality. There we go, looks pretty sweet huh If you want to save these settings as a preset for late use, you can save it by clicking this Globals button, and click save. Similarly, you can load that preset later using this button as well. For detail shot of your scene, consider using Depth of Field. To do that, first open up asset editor and go to the settings tab. Now in the render output, I’m going to change my aspect ratio to a 16 by 9 widescreen. Since we are going to do a test render first, I’m going to reduce the resolution to 800 by 450 and set the quality to medium. Then turn on depth of field and click here to see more options. Now click on Pick Focal Point and choose a spot in the scene that you want the camera to focus on. Then, you can adjust the blurriness using the Defocus slider here. As you can see, the spot I picked is in focus while everything else is more blurry. You can also test this with multiple angles in your scene. There we go, that’s pretty good. Once you’re happy with the result, you can increase the resolution, turn off the interactive mode and produce a final render. Depth of field is not always necessary, but it can be an artistic shot that's a great addition to your set of pictures If you use Photoshop for post production, consider using Nik Collection. I’ve mentioned this before in a previous video but I’m going to mention it again because it’s such an amazing plugin. Plus It’s free, so i’ll leave the link in the description box below. Before I use the Nik Collection plugin, I’m gonna do some small edits in Photoshop first. let’s open our raw render in Photoshop. I’m going to use the Denoiser channel as my base and I’ll also import the Material ID as well. Now I’m going to add a background image outside my window so the first I’m going to do is make sure the Material ID layer is selected. Then I’m going to use the wand tool to make a selection around this window. Now switch back to the base image, hold down Alt and left click here to mask away the window to make it transparent. Now we can import a background image and place it below our base layer. Then I’m going to make some quick adjustment to make the background a little more faded and not too prominent. After that’s done, I’m going to select the top visible layer and press Ctrl Alt Shift E to flatten all these layers into a new image. Now we are ready to edit this using Nik Collection so go to Filter, Nik Collection, and you can see that there’s a lot of different plugins but I’m going to use this Color Efex Pro 4. On the left side, you will see a list of presets or effects that you can use to stylize your image You can also use this slider to compare the before and after. I think I will use this Reflector Efex Preset. On the right side, I’m going to change the method to Soft Gold for a different look. Now press OK. There we go, that’s pretty sweet huh. If the change is too much, you can always adjust it by decreasing the opacity of the layer. Also, you can add more than one effect so I’m going to add this Classical Soft Focus preset and adjust the strength directly inside Nik Collection. Awesome. Now let’s compare the final product with our original rendering First I’m going to hold down Alt and drag the original image to duplicate it and place it at the bottom of the layers. Then I can select all these layers and press Ctrl+G to group them up. Now I can compare the before and after image by clicking on this eye here. There you go, that’s a super fast way to edit photos in Photoshop using Nik Collection. And those are the tips for a realistic interior rendering using Sketchup and Vray.
