7 Steps for a REALISTIC INTERIOR Render in Lumion

[Music] [Music] thank you the most common question I get is how to do a realistic interior in lumion so I'll walk you through my process for getting realistic results in lumion for interior renders including the render presets and I'll show you my seven steps for the realistic interior in lumion let's start with number one references let's say you already have your room modeled but now you are not sure what to do with it and this is where references play an important role in your design for this scene I know I wanted to make a Japanese interior style this Japanese style it's a merger Japanese and Scandinavian and it mixes Earth colors with minimalist Scandinavian design I went to Pinterest which is a great source for Gathering references and inspiration and started my research for a Japanese style living room when you open any image on Pinterest on the bottom it shows you all the similar results which is quite handy you can even create a new board with just a Japanese style references by the way you can follow me on Pinterest and check my boards I have tons of references there I like to create more parts with my image references and for this I use a tool called puref you can download this for free at prf.com I just drag and drop the images here and then organize them into small groups now looking at these references I noticed that the plants are either dry or very low and dark saturated greens something to keep in mind when later building the scene now that we have our references we move to the next step 3D modeling you have your idea and have modeled your room what's next after importing it in lumion now you need to fill it with objects to start building the scene so naturally you start modeling all the 3D objects yourself right well not exactly there are tons of websites with ready to use realistic 3D models and you should only model any object if you can really find it online or if you have to contact much of your time to model it for example I like this poof and since it's quite simple I went ahead and took literally one minute to model it the same goes for the dining table and the coffee table pretty simple furniture that takes no time to model as for the sideboard I just repurposed the small model I had and rescale it to fit the scene other objects like the sofa ceiling lamps TV furniture and even the ball of figs I got from online libraries it saved me a lot of time and don't stick with just one site to get your 3D models in this project I got my models from different sites like 3D Skype polygon Mega scans and every motion high quality models make a big difference in your final design let's say I have exactly the same scene but with low quality models and without much thought put into it you can see how it looks really bad in comparison to the high quality ones and not only you should use high quality models but you should be an interior designer as well think of the proportion of your objects for the room you are designing sometimes you see a great model like this sofa on a white background and it looks great but now yeah that you are seeing and you see how it not only doesn't fit my interior style but also it's way too big for this ROM making it feel cluttered this is one of the advantages of downloading assets from online libraries if you were to model this sofa it will take a lot of time to then realize it doesn't work at all like this I just searched for a better one that will fit the design and don't waste time and the next step is building everyday life into a scene after you have done step number two as with everything that the computer makes it's all perfect the chairs are perfectly aligned the edges are with a Sharp 90 degree angle and the surfaces are perfectly clean this is the part where you look around you and analyze how surfaces are in the real world probably full of imperfections some scratches and small dents look at your desk is it a 90 degree sharp edge probably not there isn't anything with these sharp edges in real life that's where you come in you can start building this everyday life into your scene rotate the chairs and move them slightly move and rotate the TV Furniture drawers do you see these paintings to make them look like they are not simply glued to the wall I have rotated them vertically so it looks like they are hanging on the wall do this in every scene but in a very small amount or else it will look like everything is crooked and that's not the image you want to pass you can also add some personal objects to suggest that someone actually lives here a blanket on the sofa a book or a notepad all of these details tell the story and help you create a realistic scene do the same for the edges for everything that you see with a Sharp 90 degree Edge you can either bevel the edges in the 3D model implication that you use or you can simply do this in lumion select the material now in the material properties click on this Arrow at the bottom to open up the advanced settings now go to the fourth icon that looks like a clock and you will see an option called edges just drag the slider to have some bevel this creates a highlight on the beveled areas which helps with the realism as for the surface imperfections you can add them to lumion by using decals but actually let's hold on to the surface imperfections for a while because it will be part of the next step materials and by the way if you want to take your renders to the next level you can join my illumine rendered course the link will be in the description below so about the materials one of the biggest advantages of using real-time applications like lumion is that you can apply any material and see in real time how that works you have thousands of options to choose from what materials marble concrete all of these play an important role in your design and even small differences make a huge impact on your room and again by using lumion even if a wood texture has almost the right color you can even adjust the saturation for example if you feel the final design will benefit from it also the material should have balance don't simply use the same marble throughout the room use moderation so you can make some elements stand out with that being said instead of going to Google and searching for a texture and applying it to your project I recommend using PBR materials these materials have the correct physical values and it saves the guesswork with PVR materials you simply load the textures into lumion and that's it there's nothing else you need to do you can go have a coffee now and relax there are plenty of sites you can get these materials from and I'll leave a few in the description below but let me now guide you step by step on how you can download and apply a PVR material from polygon website into lumion so head over to polygon.com now click here on Textures and if you just want to test it first you can click on this section that says free I'm going to select this wood flooring and when you click you can see here the dimensions 2.9 by 2.9 meters moving mapping scale is in meters so we'll have the same value of 2.9 to our material later I'll select a 4K resolution and on the download options I have here several maps for lumion I need the diffuse displacement gloss normals and reflections now before we apply the material in lumion do you see this Reflection from the exterior this is because we don't have the reflection control on our scene we need to go to tools and then select the sphere called reflection control place it in the center of the room now it's reflecting correctly let's load each map in the correct slot inside lumion with polygon you need to invert the normal map and to invert it you just click here on the texture and now go to the right where you see the bigger preview and on the top click flip normal map direction now it's with the correct lighting to load the reflection map you first need to select this icon which size texture masks reflectivity now you can load them up finally we can add a value of 2.9 meters on the map scale which is what we saw on the polygon side by the way you notice I selected a 4K resolution right there are other options you can select like 2K or 1K see the render with 1K resolution and now with 4K resolution you need to use your best judgment when it's needed a higher resolution for your materials for objects that are further away from the camera you can use 1K texture so that the difference would be so noticeable in normal materials you can see which texture resolution a material has by hovering over the material name and seeing the 1K 2K or 3K at the end this indicates the texture resolution another mistake I often see is using the wrong scale let's take the wood floor from polygon side as an example we saw it as 2.9 meters so if I apply a map scale value of 10 this will result in a new realistic texture and not so realistic render right usually you can get away with a 10 to 15 scaling difference but more than that and you are damaging your scene another common problem is texture repetition usually you can hide this problem when adding furniture and other elements or we can use surface imperfections remember I told you we would come back to this object now it's a perfect time you can use decals to add surface imperfections to both add realism to your scene and help break the texture repetition let's add some decals by going to effects decals and here you select from the big variety they have you see this section wall paint these work great to give some variation to the wood floor I'll make it look like it's with some areas cleaner than others and if the selection of decals Lumin has is not enough you can import your own custom decals by clicking this lumion logo now on the top right corner I'll expand the settings by clicking on this arrow and I will import some scratches I've downloaded mine for free from ablcg.com you can search here imperfections and select the one you like now back in lumion I import the texture and adjust some of the values and this is the before and after now that you have added high quality materials to your scene we move to the next step which is composition when you are taking a new render you are basically a photographer in each shot you have to get the best angle to promote the best out of your design and as any photographer you need to understand the basics to be able to get a good shot there are three things you need to master focal length exposure and Rule of hurts focal length is the angle of view a lower value will result in a larger field of view but it will have a lot of Destruction this is a good example of how focal length changes our perception do you see how different the face of this character looks if we go from 10 millimeters to 100 millimeters the same applies to an interior space using a 10 millimeter focal length will make a room look bigger and it allows you to show the whole space in one shot but the image doesn't look nice and you don't need to show the whole space in one shot you can use 30 millimeter for this room and instead take two or three renders showing different spaces of the room you can even use a 50 millimeter focal length to take some detail shots with a nice depth of field a lower focal knife works well on small and Tighter spaces like a small bathroom for example let me show you how you can select focal length in Lumia click on the photo mode icon in the bottom right corner then if you're over over the image you see a new menu shows up on the bottom here on the focal length you can either drag the slider to increase or decrease or you can double left click it will turn red now press backspace and insert the value you want these two buttons on the left it's for adjusting the horizontal perspective and the other one is to set your camera height to 1.6 meters I recommend using a lower value between 1 to 1.3 meters it's the ideal there is one effect you should always add when taking renders at a human height level the two-point perspective this will make your vertical line straight resulting in a better image don't use it when taking aerial shots as you see the image gets really distorted the next thing you need to master its exposure this is the amount of light you let in the camera sensor the higher the exposure the more light you'll have on your seat so if your scene is too dark you can increase the exposure to compensate to adjust this value in lumion in photo mode click on effects then camera and select exposure now you can simply drag the slider to increase or decrease the exposure and lastly use the rule offers if you imagine dividing a photo into nine equal zones using horizontal and vertical lines that forms your rule of Earth's grid you can place the most important parts of your image along these lines for a better render lumion already has this compositional helper built in to guide you if you right click on the render region in photo mode you can see this horizontal and vertical lines show up that's your rule of hurts so you see how I can move the camera and place these items along the lines to have a better image now that you set up all your cameras you are ready for the next step lighting one of the main problems I see when people try to create realistic Interiors in lumion is that they only rely on the daytime lighting nothing else you shouldn't be afraid of using artificial lining to complement with lumion it works quite well for interiors take this interior for example I'm using spotlights for ceiling lights and these two lights I rotate them slightly to the wall so we have more lighting detail on this same wall you can see that these two lights are not exactly in the place as the ceiling lights but sometimes you need to fake it to have better results I'm using a line light here and a very important tip rotate them like this because since the area lights and line lights don't have shadows this way it creates the illusion of the Shadow and reduce the falloff of the light so it's not lighting the whole scene remember this light is just an accent light now about these lamps here you see they have this effect like they are turned on right if I just have a spotlight inside you see that they look like the light is turned off to fix this we just need to add an area right on the top of the lamp make it to really small and reduce the Fallout now duplicate this slide move it down and rotate so it's pointing upwards and now we see that we have this effect like it's turned on one final note for this effect to work you need to set your lamp material luxiness to the maximum I usually add an area lights by the window to boost light from the exterior to the interior I leave it with the default color temperature which is daylight and increase the falloff so it doesn't light up the whole room remember it's good to have a balance between light and dark areas and finally I had a spotlight you can use this one lamp 23 it will have the same effect as the area light but it creates shadows and highlights especially here on the ceiling oh I almost forgot I only use emissive lights to show that the light is turned on just add about 10 20 percent of emissiveness don't overdo it or else it will look too bright and unrealistic now that you light up the scene what else is missing the render effects as I said in the beginning of the video I'll guide you step by step which effects to use and the settings you should adjust so the next step is lumion render effects to lumion makes your life easier by giving you rendered styles when you are in photo mode just click this button that says custom style since we are making an interior I'll select the interior Style let's just take a render with this render style and see how it looks well it's not too bad you see that by following the first steps of good 3D models and high quality materials and a great composition we already have a good image in seconds let's see what you can adjust on this preset to make it better on the shadow increase the coloring to about 20 then the brightness leave it at about here only Shadow this is where many people have that super dark corners on the walls because this effect is all the way to the maximum and as you see it doesn't make the image look better I usually leave it at about 0.1 for interiors on the shadow correction you can leave this setting all the way to the left the rest leave it as it is next is Skylight as the name says it's the amount of light from the sky for interiors I use the first slider to the maximum so I have the most amount of light possible the second slider is how much your shadows will be affected by the Skylight in color so a higher value will result in a more bluish scene and the lower value more neutral scene I recommend using this in a higher value only when you are rendering a blue hour scene so let's leave this one at about 0.6 we don't need these two toggle options for the interior and the render quality is set it to ultra this will make your render Times Higher but it will have a better quality next is Hyperlite this effect creates slight bounces on your scene the higher the value the more light bounces and the brighter your scene will be since my window is quite large I will decrease this to about 25 percent if you have smaller Windows you can probably go for about 50 percent as for the reflection here you need to select which areas you want to have the best quality for the reflections we can select the floor the walls the ceiling and the dining table increase the plane margins to the maximum this will make this plane catch more areas of reflection until 25 centimeters and so this way you don't need to add more reflection planes having better performance both for working and rendering next is called a correction and I'll make the color temperature to about 0.2 and decrease the brightness to about 0.5 increase the contrast to 0.7 as for the exposure right now is too high let's reduce it to 0.6 I'll add just a little bit of sharpen to about 0.2 and the sun effect is not working currently because we have the real Skies effect turned on for this scene let's make the fog density at 1.4 the fall off at zero almost reaching 0.1 the fog brightness increased to 0.9 and brightness to 6. next we have real Skies I'm not making a blue hour scene so let's replace the sky go to overcast and select the second sky now in the settings put the heading around here and increase the brightness the rest will leave it as it is that is another effect we must have now the global elimination click on the effects on the top select lighting and choose Global illumination this will create white bounces from the artificial lighting click select lights and now instead of selecting all the lights which will make your scene quite heavy and you will have performance issues you can select these four lights and over here these two increase the GI amount at the bottom and press ok now adjust the follow-up speed until you see the ceiling getting lit by the lights increase the reduced spots all the way up and now that you're done with the global elimination disable the preview Spotlight GI and shadows this way it saves on the performance and it will be visible on the final render lastly you can add some lens and Perfection effects like the vignetting the chromatic operation and the bloom effect and remember to add a print poster enhancer which you can find under the tools category if you are going to render a 4K or 8K image after you've followed all these steps you should be able to have a render that looks like this and I recommend you checking my video about the first thing you should do before starting any project which will help you understand how I achieve realism with my 3D renders I'll leave a link up here and in the description below and I'll see you in the next video
