Getting Started Rendering in Vray (EP 4) - Interior Lighting in Vray Using Artificial Lighting

In this Vray and SketchUp tutorial, learn about the different kinds of artificial lights you can use to light your interior renders! Learn to use sphere lights, spotlights, emissive materials, and more to create realistic lighting in your interior models!

Today I wanted to talk about some of your options for lighting an interior model within SketchUp without using the environment lighting.
You’ve basically got a few different options for lighting your interior models with artificial lights – this is assuming that you don’t want to light your model with the environment lighting in Vray (sunlight and background lights).
To start off, turn the sunlight off within your lighting section of your Vray asset editor. You’ll note that you still get some exterior lighting from your background image, which you can adjust within your settings section.
Now, let’s take a look at some different lighting options.
To start off, let’s add a sphere light to your model. Basically, a sphere light is a light that emits light in all different directions equally. You can adjust the power of the light both by scaling it up and down, and by adjusting the intensity within the lighting section of your asset editor.
One thing to note – if your image is not bright enough, that doesn’t necessarily mean you need to go in and run the intensity of your lights up to a super high level. Instead, go in to your camera settings and adjust your camera exposure to bring your lighting level up.
In this case, I’m going to take this point light and adjust its size so that it fits within this lamp in my model. I’m also going to adjust the radiant power units to Watts and set it to something like 80. Though the visible wattage of the light doesn’t really correspond with the power usage of bulbs, this still allows me to set my lighting in a way that it makes sense to me.
Now let’s add a couple spot lights to our image. While a sphere light is a light that shines in all different directions, a spotlight is basically a light with a direction associated with it. Note that when setting your spotlight, you can either just single click in order to place it, or you can hold the shift key to set things like cone angle, penumbra falloff, and more.
Note that when we initially set this light, the light itself casts a very defined edge, which isn’t very realistic, and doesn’t allow the light to really move into the rest of the room. However, if we adjust the Penumbra angle setting, you’ll note that your light edges become more blurry, and more light also makes its way into the room.
We’re not going to talk about IES lights too much in this video, but these are basically lighting information files that you can download from lighting manufacturers to simulate properties of actual lights, like bulbs, etc.
An omni light is very similar to a sphere light. Honestly, I’m having a bit of trouble telling when to use which one, so any of you Vray experts out there leave a comment down below and let me know!
Finally, you can also create light within an interior render using an emissive material. An emissive material is basically a material within Vray that emits light. You can use this for things like TV screens, lighting faces, and more. In this case, I’m going to add an emissive TV screen, as well as an emissive faced material at my spotlights, otherwise they look funny.
Once you have your lighting the way that you want it, you can do a non-interactive render to create a more detailed rendering from your image.

Omni Light has decay and shadows radius, it's meant to be more of an "area light" to light up whole areas of a room. It's not that "it's not as bright", but it's because the decay is set to inverse square by default which means the light "fade" out a lot more. Hope that helps 😊

This guy is great! His tutorials are instructive and clear and FAST! He gets to the point quickly and effectively and without distracting background music etc. Thanks Justin. V helpful

[nbernik]

Dear Justin. I have no words for how many times you have made it easier for me to work with the Sketchup and V-Ray. You are our LIGHT! Thank you very much!

[angbaoquocphi]

Thank you so Currently I am a student at university in Vietnam. And I had difficult about finance, so I did not learn Vray in lerning center. But through your videos I can learn many thing about vray and construction. And right now, I really feel happy because I learned many thing about you. Once again, I just want to say thank you very

[jerrychong]

Hi Justin, you've made VRay tools for Lighting so easy a topic to comprehend, understand and use! Thanks a million!

[vishwanand]

I simply love the way you literally comment every click with speech. Small things like these are really helpful to noobs like me. Thank you for making this video. ❤️

[haxchan]

you’re the best -and you deserve a lot more! your tutorials helped me get through my 5 years in architecture school 💕

[dirarazizi]

man when i was using twinmotion i saw you pro with it and now i had to use v-ray and i see u have some tutorial, come onnnn
much love, god bless u bro

[justlaughjokefunny]

i learned 3D & Rendering from you by following your channel tutorials .. thanks a lot

[nshclk]

I like your videos because the explanation is so clear and easy to understand

i liked your explaining. so clear. so easy. good

[Truca.B]

This is perfect. Thank you very much. It really makes a difference now that i watched your videos.

[Nova-Solaris]

Thx a lot man! Just getting stareted into rendering, but this helped a lot to understand the diferrences between all the light types.
Keep it up!

[rusim]

You are a magnificent teacher! Thank you so very much for these very informative and clearly and effectively communicated tutorials! Thank you yet again!
