-------------------------------------------------------------------
In today’s rendering tutorial, I want to give you an introduction to the different types of lights available in your rendering software. As always, we’re going to be using Twilight Render’s free hobby version, but the principles that we’re going to use will apply to other rendering softwares as well.
You can download the hobby version for free at www.twilightrender.com.
We’re going to start with a very simple scene that I’ve created. It’s a pair of chairs in a room without a window. This may not be the most realistic space, but it will allow me to illustrate some of these principles a bit better.
Note that I had to adjust my camera FOV using the zoom tool to get more of the room in my camera shot. To do this, activate the zoom tool, then click and drag while holding the shift key to adjust your FOV. Once you have your camera where you like it, make sure to add a scene to save your viewpoint.
Now we’re going to start off by simply adding a light. To do this, go up to the Twilight Render toolbar and select the option for “Create Light.” When you click the add light button, it should also pop up the edit light window.
Start off and just click somewhere in your model. You’ll have to click 3 times - once to set a reference point for the light. This is basically a base point, but not the location of your light. Click again to click the actual location - what’s nice about this is that you can use it to inference off an object, like a wall. Finally, click a third time to set a target, or what a light is pointing at.
Now that we’ve got a light in our model, we can edit it. I’m going to talk about a couple basic kinds of lights in this model, but I’m also going to skip over a couple of the more complex ones.
The first kind of light is a point light. A point light is a light that eminates light in all different directions. If you put this in the very center of your room, it will light up all parts of the room equally. It doesn’t matter where this kind of light is targeted.
The second kind of light is a spot-light. A spotlight is a light that actually points at a location. This is the kind of light that is affected by where you targeted it.
You can re-target this light by right clicking on it, finding the Twilight Render menu, and clicking on a new location.
The final kind of light I want to talk about is an emitter. An emitter is a material that emits light. You can set the amount of light emitted by a material in the material editor.
Let’s talk just a bit about the settings over here in the edit light toolbar.
We’ll get into these more in-depth later, but generally, here’s what they do -
The size adjusts the size of your light.
Attenuation affects the way the light loses intensity as it moves away from the source.
Power affects how bright the lights are. One note - don’t adjust the brightness of your image by adjusting the power of the light. Use realistic brightnesses for best results. You can use the exposure and gamma post-processing options to affect the brightness of the overall image.
You can select the type of light by selecting the box next to the efficacy.
You can change the color of the light with the box off to the side.
We already talked about the type of light.
Finally, at the bottom, you can affect the type of scene that your preview shows.
Now let’s go through and run our render.
Let’s start by running a render with two point lights. As always, you want to run your render on the preliminary preset first just to make sure that your render is doing what you want it to.
Now let’s change this to a render with a spotlight.
Finally, we’ve got a light that I downloaded from the 3D warehouse. I’ve changed the light color to something realistic, like 3500 K, and I changed the lampshade to a translucent color.
You can see how this translucent color affects the way the colors look in your render.
Finally, you can adjust your brightness by changing your exposure and gamma in the post-process options below.
That’s where I’m going to end todays video. This was a quick runthrough of the way interior lighting works in the rendering process. As always, leave a comment below and let me know what you thought.

Thank you very much, Justin. I wish I could like this video more than once.
Lol - I appreciate it!
Hey - this was fantastic! I used to painstakingly export to Blender for lighting/rendering but then I watched this and within 30 minutes I was adding random bulbs to every possible surface. Thanks!!! I think?
Another amazing video. Two-thumbs up!

VERY HELPFUL MANY THANKS
Excellent video as always. When choosing the type of light, do you know if twilight rendering has a candlelight setting?
thankyou! very helpfull
its lovable thank you
Glad you liked it!
Superb sir.
Like & love you from India 🇮🇳 really like your talent and respect from deeply my heart ♥.
He is best teacher..
I'd like to use my existing Kerkythea point lights in Twilight Render Hobby (free version). Is there a way to do this? I'm using older SU6 and SU8. Thanks for the videos!
Thanks for this.. I'm using Vray, are you familiar with that too? This twilight plugin looks like it's much easyer to use!
Hi Justin, thank you so much for your tutorials. Do you know what's the best Twilight settings (i.e Exposure, Gamma, Saturation) that could give you a more Close to Reality look of the room indoor Illumination when using the IES lamp values with no Outdoor Ambient or natural light contribution. Looking forward to your reply.
Great video and super helpful thakn you so much! I got everything up until the rendering part, my "Render" box where my room perspective view is supposed to be keeps coming up as a grey box, any suggestions?
Thank you very much for this clearly tutorial.. 🙏🙏🙏
Glad it was helpful!
I follow your tutorial right now i made a simple house.. Amazing its litghning my project thank you very much.. 😇😇
Sir, i want light material for thea v2.0, for sketchup, can u send me ur on model link that have all lighting material, so i can import them on my sketchup 2018 for thea render, pls help sir
the lighting off the tv looked like a chalk board. but man, you run through that stuff so well and so clearly. awesome job. i didnt know about the exposure too much so i was running bulbs about 1000 watts. oops. twilight so far is my favorite rendering program. i have it on a more powerful pc and its just amazing the results.
Lol - I used to do the same thing - using the exposure is WAY better. Thanks for watching!
How do I download this scene so I can learn, thank you for helping us a lot with your knowledge
Nice video
Glad you liked it
Thank you sir. Very helpful for me who just started learning Twilight.

Fantastic Videlo
Thank you :)
Hello. Thank you so much for this video. Very helpful. Just a small problem...when I try to render, it doesn't work, it just shows this checkered image and then when the render is complete, the image is just blank. Please, help.
I take it that there is no hard-edged interior lighting that displays inside the preview window, the way that sunlight does on a model's exterior? I'm just looking for something I can use as a guide to hand-rendering shadows. Thanks! Very good tutorial, btw, ;) BTW: If I use a Section Slice to "remove" a ceiling, would the outdoor Sun have any influence on the interior? (For once, someone doesn't *_want_* soft shadows!)
thaaanksssss!!
Thanks lecturer
Thanks for watching!
Hi! I'm rendering my image, but all my sheer curtains are turning out gray. Could you please help me understand what I'm not doing right or not clicking right. Thank you!
How do I use the light, but keep the sketchy style I set up in the room?
Hi! I love this series of twilight videos. the first few times I ran a prelim render with 1-2 light sources it rendered quickly. Now it takes FOREVER to render a prelim (I have No idea how long it is actually taking, I've never had the patience to wait more than 15 min for a prelim)! I don't know what happened. I purged unused materials, and deleted all lights and tried to start over with just 1. Any tips?
How big is your file? I've never had a preliminary render take that long...
Very nice sir
Glad you found it helpful!
is there a way to implement the lighting you choose into your sketch drawing while you work? can it only be utilized when exporting renders? in other words id like to see the light when im working in my drawing... is that possible?
I don't understand - the lighting is specifically generated by and rendered in your rendering engine
But whenever i unhide the wall it puts me out of the box ... any suggestions plz
Yo bro, you forgot to put your cap on, but great vid as always. Luv you man
LOL - it does happen occasionally ;p
Good video.How can you work with natural light from a window as opposed to artificial?
Hi there! I'm planning on making a video about how to do this in the future. However, in general, you need an opening in the building, and I think you need to use one of the sky environments (I think physical sky) to light your model. Thanks for watching!
Love your tutorials, not to long and plenty explanation. Thanks a million ....( BUT..Sorry but the back ground music is kine irritating... :-( and makes it sometimes harder to concentrate. ) BUT... another but a positive one, i will keep watching your tips and ticks and hope to see many more. And i will support you sometime ( $ ).
Thanks Marco!
I'm having trouble getting the program to render my ceiling and flooring correctly. Any suggestions? I just downloaded this today so speak slowly and use small words. Thanks!
Hi Rebecca - you're going to have to be more specific as to your problem. What's it doing (or not doing)?
Is the Twilight addon still free by any chance? I can't seem to find the "hobby" version of it.
As far as I know...
Thank you for this great tutorial! I am only wondering, can you also make the light source visible as well? I mean like to be able to see the actual light bulb shining and not just casting light?
You'd want to apply an emissive material to the bulb to make it glow - the light comes from the artificial light object, the glow comes from the emissive material
@@Thesketchupessentials thank you very much!
hi may I ask. I already tried to add interior lighting but when I tried to render using twilight the light dont come up what would be the possible problem.Help me pls...
I'm going to need more information. You add interior lighting, then when you press the render button, the lights that you added aren't actually generating light?
@@Thesketchupessentials Hi, i found this tutorial only now and have the same problem (light dont render, only interior) I'm usink sketchup 17
Does Twilight hobby work on the free version of sketchup?
That depends. It does not work on the free online version. However, it will work with the free downloadable Make version. Thanks!
super video ! but god daim the pops in that mic ! :)
Which is better for both interior & exterior rendering Vray or Twilight?? What are the differences?
Depends on what you value. Vray definitely has more options, but is more expensive
Thank you and just what I wanted to know. Since 2 years ago. I wish to have my Patreon subscription ended. This is another example of knowing you were never listening to what I was saying I wanted to learn while being your Essentials student.. You never mentioned this series was available and I asked many questions and told you my goals? The "conversation with "you guys" seems to be only one way?
Well first of all I'm a bit disappointed (and confused) to hear you say this, especially considering the number of questions I answered both as you went through the course and as you were in the community. I tried to be as responsive as I could be and I'm sorry you feel that I didn't meet your expectations.
Last we spoke, your goal was to learn to use Blender for 3D modeling and rendering, which as I recall was the reason you left the community (which is fine by the way, but I can't support Blender modeling inside a SketchUp community). I'm not sure how a video on a series about Twilight Render aligns with that goal, so once again...confused.
As to the Patreon subscription, you're going to have to go cancel that yourself. You have full control over your support and I actually can't go in and change your subscription in any way. Thank you for your support
Thaaaaaaaaaaank you! :))))
Glad it helped!
so i set lights in twilight and every render was super fast, then i was like hmmm i actually would rather some materials to emmit light, the render took SOOOOOOO long even on prelim, is this expected or should they run about the same?
They talk about that a bit in this forum post - www.twilightrender.com/phpBB3/viewtopic.php?t=4763 - seems like adding emitters usually really slows down renders, so be careful how and when you use them, and also try to minimize the number of faces that are emitters. Thanks!
yeah i came across that forum post before i asked you :D
Where can I download the hobby version on your website?
You can download it in the first link in the description
Thank you very much.
2:55 light tutorial starts
thnx
bro I need more videos on twilight render
I have a kinda big problem here... whenever I click on the render start button..the render stops at 2seconds and leaves me with a blurry picture od the template itself. Doesnt matter which quality I choose or anything...when i add light emitting object twilight wont render, as soon as I remove the emissive source it renders normally.. Please do help, im a newbie at all of this and I really need advice. Thanks in advance
Hmm...interesting - is it a really big model? It may be a RAM issue, I'm not really 100% sure. You may want to post a question in the Twilight Render forums - www.twilightrender.com/phpBB3/index.php - Those guys know a lot more about this than I do. Thanks!
TheSketchUpEssentials It's not huge but it does have a fully furnished enterrior which posseses somewhat complex shapes...and lighting up the place is essential for this particular project.. I have 16GB ram..
I'll check there for help too, thanks.
16 GB ram should be plenty for what you're trying to do. Does it act the same even if you select some of the interior presets instead of the exterior or easy presets?
I just tried all of the interior presets...and unfortunately I got the exact same results.
Now I tried on a new model with just two simple cubes in it and got exactly the same results...ouch
When i try to unhide all, wall comes in front of my camera :(
So...move your camera?
hey, when i inserted light, my render slowed like a 1000x times, you know why?
i used a couple of furnitures as well
What kind of light did you insert? Second question - did it slow down after you added furniture, or before? If you added a lot of geometry heavy items, that could be slowing it down as well.
How make 360 image using Twilight render
Ajay Jadhav Dear dont use twilight, use thea render which is better for sketchup 2018
hi Justin, I am completely new to Sketchup and Rendering and so even this is a little too complicated do you have any other videos where you go through the tools step by step and please don't do things "real quick" as it is too hard to follow. Thank you great work by the way.
You could probably start here (th-cam.com/video/go8UrmmZ6TE/w-d-xo.html)
and keep going please
Glad you liked it!
I love sketchup, but unfortunately I have a problem learning.
so i cant use it in the real work i have done
can you help me please
I don't understand - you haven't listed a specific question or issue...
Excellent. I'm afraid I don't speak English well. i cant get it right. But thank you again.
Why i cant Render it...???
Based on the info you've given me here...no idea?
You went too fast when it got to the material editor part. How can I create lights that’s aren’t spot or point lights
Sounds fun :)
daming satsat
??
rendering using "twilight render"
????
I have no idea - I've never tried to create a 360 render in Twilight - not even sure if it has this function - did you check their website?
Where is your hat?!? :)
Lol - I'm sure out of 900+ videos, I probably have less than 10 with no hat ;p
不知道你能不能看懂中文，但是我希望今后您把中文字幕给配上就好了，听着太累了
I don't, but I think I translated this properly. Unfortunately, at the moment, I don't have the capacity to provide better subtitles. Maybe this is something I can improve in the future. Thanks!
