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 😊
As always, that's an excellent explanation! Is there a time or usage when you prefer to use Omni over Sphere Lights in your renderings?
@@TheRenderingEssentials I guess its better used for just generally having more light in an entire room, where as a sphere light from a lightbulb or lamp would be better for more realistic light sources?
@@TheRenderingEssentials Been comparing sphere and omni, and in the case of a narrow space that needs to be lit evenly (apartment hallway), several omnis in a row set to 2 Scalar and decay at Linear makes everything evenly brighter, as opposed to an invisible sphere light which will have the effect of a lantern suspended in air (hot spots etc).. can send you test renders if you're interested to see?
I have literally been searching for weeks on how to light up a large room. I use the program for work and we are new to Vray and for me the omni light did nothing...changed it from inverse and what a difference!!!!! The answer I was searching for was right there in the comments. THANK YOU SO MUCH!!
@Maxton Gunner why are you like this
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!
Thank you so much..... 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 much......
Hi Justin, you've made VRay tools for Lighting so easy a topic to comprehend, understand and use! Thanks a million!

@@TheRenderingEssentials
Yeah, I liked them.
you are a life saver
Just love u r explanation
I was just about to make a comment on another video about a tutorial on lighting and here it is. This channel and SketchUp Essentials are great and have helped me through so many modelling issues I’ve encountered. Keep up the great videos. Have you thought about doing any Revit tutorials? Your way of teaching is faultless. Thanks again. 😁
Thanks very much! At the moment, probably not - if I was to do other tutorials, I'd likely want to get more into Unreal, Unity, Blender, or something like that rather than Revit, though I'm always open to new ideas in the future. Thanks so much for watching!
thanks for this tutorials.....
man you are a life saver !
Glad it helped!
Amazing. Thanks for helping.

Appreciable... Well done... Doing great jOb
Thanks a lot 😊
Thank you! Thank you! Thank you!
:)
Many thanks for you
amazing video
Super helpful... Thank You. The more I get into sketchup, I realize I would need a really good computer with graphic cards because the more details I put into it, the loading time keeps increasing and it has become quite significant comparing to back in the basic days. Hehe but thanks so much for your efforts and helpful tips and information.
Perfect.
ı wathced a lot of videos about this light issue but ı cant handle ıt then ı just watch your video and learn everything THANK YOUUU
Great! Thank you so much!
Thanks very much!
Thank you so muchhhhh!!!!!!!
you are awesome!!!
thank you so much!!!!!
You're welcome!
thank you sir hope more people will see your kindness and more subscriber to come..
Thank you. I have been following your tutorials. I can't find episode 3. Is it there?
Great man thank you
You're welcome!
Love the videos, thanks!
Have you thought of doing private lessons? For instance, I'm imagining a 45 minute appointment or something, where we screenshare while I build what I'm working on. Maybe you build the same thing on your end simultaneously to quickly show options and what to do. Even without you building it too, having someone walk me through things live so I don't have to dig through text or video to find something specific, this could be a very helpful service. You already have the platform to promote it too :) Just an idea.
Hallo Justin, I like your videos because the explanation is so clear and easy to understand. Thank you very much. Do you have a video on Vray menu for example explain emissive , refraction, reflection and how to use them. Thank you very much.
Thank you so much
Extremely helpful
Glad you liked it!
amazing! thanks you!
Thanks for watching!
Thank you Sir......
Nice class very useful class... Thanku thanku very much...
Thanks for watching!
I did exactly the same but for a reason or another I can almost see this reflects of my spot light even when I adjust everything, is there something I can do in the settings?
Thank you !

Awesome video
Thanks! :)
hey can anyone ping me Ep 3 of this tutorial playlist, can't find it.
Thanks. Great, greeeeat lessons!! Is there EP3?
hey i cant find EP 03, can anyone please send me the link ?
Thanks a lot for this valuable information. I tried them all but the spot lights they don’t work with me and it’s not even shown there do u think it’s something in my sitting?
Thanks again
Hi thanks for sharing your great but can i ask something which computer specs your using ? Thanks
well done good on all accounts
Hi! Can we make the edge of sphere light more smooth?
I use the omni light inside the light fixture so you can visualise the light source, I usually use it with an ies or spot light
Hey man really great job with the tutorials.. where is episode 3?
Muchas Gracias, Thanks You 👍👍👍
Thanks for watching!
j'adore
This is great! But where did EP 3 go?
Can you export the work to use in X-Plane?
Thanks bud.
thanks a lot man thanks alot
Thanks for watching!
Hello Justin I don't know how to thank you for all your great works. God will reward you
Please I have this challenge in v ray. during my interactive rendering, I still find that the colors I applied to my interior scene still goes all that white everywhere. I applied red to towels, but still showing white. Please where did I go wrong?
Thanks
thanks bro
Thank you for this video Justin. I am a new subscriber and I really find your videos really helpful. I am new to Vray but have used Sketchup for many years now.
I have a question though. I am using a free trial version of Vray 5.0 and when I place any type of lights from Vray into my 3D model the interactive render screen does not show the illumination from the light automatically like yours does. Instead I have to individually change each light source I've used in the model so that it's in wattage so that the illumination appears. Also, the light source (spotlight, sphere, rectangle, etc) in my model appears in wire frame rather than a solid white object. Could you please explain why that is?
Thanks for your expertise.
Hi Justin, great video, very helpful but hey we have a question - we have SketchUp 2020 and we can't get the spotlights to show up in the V Ray render no matter what we do. Clicking them on or off, changing any of their settings, nothing. All the other lights (rectangle, sphere, dome, etc.) work fine and their settings are adjustable. Would love any advice or recommendations. Thanks.
I wanted to know one More thing. If I choose a custom material which is fabric. So can I apply the properties of built in fabric material or any material in that case
Which laptop do you use and please share the configuration. I have bought HP envy 14 and i have 16 gb ram and still experience lagging in my sketchup model and while rendering too.
