Lighting with V-Ray for SketchUp – definitive guide part 1

By Nomer Adona
Previously Nomer Adona wrote a simple tutorial entitled “Interior Lighting for Beginners” which was published at CGpinoy.org. In that tutorial heused version 1.05 of V-Ray for SketchUp. Since many new features have been added with the latest version of V-Ray for SketchUp, we have
decided to do this mini series of tutorials with the latest versions.
In this first tutorial I will be using V-Ray Beta version 1.48.99 (V-Ray for SketchUp User Manual Version 1.48) and SketchUp version 7.0. I
will be focusing on IES, Spotlight, Rectagular and emissive lighting. You will learn how to create a realistic lampshade material and how toposition the rectangular lights to achieve the right effect for your shade. In this tutorial I will be using the same model that I used in the previous
tutorial “Interior Lighting for Beginners” and will be adding components and materials to achieve the desired effect.
Here is a screen shot of the particular interior that I will be using.
Basic SketchUp Interior
OK lets begin!
1. IES Lighting
I have done this in a previous tutorial here at SketchUpArtists: Basic IES Tuorial using V-Ray for SketchUp. The only difference is instead of
using a rectangular light to show the light source, I will be just using a Emissive map.

Emissive Map and IES Light Icon
Here is the material I used for the Emissive map.
Settings for Material
This is the first render.

2. Spotlight
Together with IES lighting, this is also a new feature with V-Ray 1.48.66 and up. Since this is a tutorial, allow me to put 4 spotlights in my fourrecess lamps.
4 Recess Lamps
The Image below shows the position of the Spotlight icon. I also use a Emissive map on the light receptacle.

Position Spotlight Icon
Here is the settings for my Spotlight. For me the most critical setting is the Shadow Radius which controls the softness of the shadows, ShadowSubdivision controls the smoothness of the shadow and last but not the least is the Penumbra Angle. In the image below I used 0.3.
Spotlight Settings
Here is the render using Spotlight. In this render I used a very low resolution. This is the reason why I have splotches and grains. This can be
corrected easily by using higher Subdivisions and Samplings.

3. Lampshades
Here is a simple lamp I modeled in SketchUp. I will show you how to place V-Ray rectangular lights.
SketchUp Lamp
Here I hid the shade of my lamp to show how I set up my rectangular lights. V-Ray rectangular 1 and 2 run along the height of the shade. Theyare double sided, visible but they don’t cast shadows. The one that casts shadows is the third V-Ray rectangular light. This one casts shadows,
double sided but I made it invisible.

Rectangular Lights
Here are the settings of my V-Ray rectangular lights.

Lampshade material: This is a 2 sided material with about 70% gray mixture.

Here is the resulting render.

Render With Rectangular Lights
Lastly, I will add a few more components. A special thanks to a friend BTH (Trang An) for some of these great components.
SketchUp Scene with Extra Components
Here is the render.

Night Scene
I also attempted to render with the same scene, this time with GI and BG Colors on (no mapping).
Night Scene 2
Cheers! I hope you will wait for the second part of this tutorial and my guide to lighting with V-Ray for SketchUp.

Styles
One clever way to enhance your final presentations is with the use of a special feature in SketchUp called Styles. Styles are collections of displaysettings, including new options like Watermarks and Sketchy Effects, saved in the new Styles palette. You can use Style Builder to create custom
non-photorealistic (NPR) Styles for SketchUp. NPR Styles can make your models appear hand-rendered, super-technical, and everything in
between......Read

Thanks for the great tutorial! But everytime i try rendering a completly enclosed space i get a totally black rendering,its driving me crazy!Could you please post the complete vray option settings ( camera setting, GI setting etc..) for this sort of enclosed space.
9. nomeradona on April 2nd, 2011 4:42 pm
i guess your physical camera is on.
10. rarchitect on April 3rd, 2011 2:15 pm
Nope, thats what’s driving me nuts, physical camera is off. That’s also why i was hoping you could post the complete vray option settings.

12. NoelFRJ on April 29th, 2011 2:52 am
Thanks!!!! I love to learn this way!
13. onin aure on April 29th, 2011 8:57 pm
uhm sir. i just want to ask how did you modify the default settings when dealing with the lamp shade material? i mean, i’d tried it but thematerial was still opaque. how would i use the two-sided material and the right translucency for it? thank you sir. hope you could help me.
14. NoelFRJ on May 1st, 2011 9:36 pm
I have a problem, on the light editor i cant modify the intensity of lights and also in other parameters is the same problem!
When I render and image whit rectangular lights they appear black, even if I reverse it´s face. Other types of lights just dont appear theprogram doesnt include them in the scene!
15. nomeradona on May 4th, 2011 4:43 pm
@onin. i think you need to click force one sided material. as for the material the rule of thumb to me is to have 70% dark gray. (front 70%and 30% back materials.
16. nomeradona on May 4th, 2011 4:50 pm
@Noel, what version of vray are you using? I think you are using vray 1.05.33 maybe if the other lights icon are not showing.

such a grt tutorial!! u r doin wonders by tutoring beginners like me!! Thanks a million for ur efforts!!
25. derek on December 4th, 2011 11:43 pm
your renders are awesome. quick question though: how do you get the light to shine through the lamp shade? is your shade just a regular
white color? is it just one plane? i have some shades that have a 1/4″ thickness; is this not the way to go? your response will be greatlyappreciated!!!
26. Paulo Autran on January 13th, 2012 9:46 am
Hi. I want to study these cases, where can I find these scenes (Sketchup)? Sorry , i don’t speak english very well

29. meg on March 6th, 2012 7:24 am
I’ve the same problem as Noel’s. When I put rectangular lights, it appears as if its an uplight and it’s black. I dont have problems with myIES, Spots and Omni. Will greatly appreciate your advice. Cheers!

34. Clarisse on October 11th, 2012 11:58 pm
I had the same black screen problem as a lot of people here..i suggest you try to zoom in a little..sometimes the render renders a little farback and you are inside a wall. That’s what i discovered. Simple but sometimes it’s the problem.
35. admin on October 17th, 2012 1:26 pm
Thnx for that ClarisseJames
36. Pablo on November 26th, 2012 2:43 am
Hey, Great tutorial…
I have a question, how do you do for the reflection of a mirror, I saw you have one on the render.I can’t make that the textures reflect, just objects and colors. I wonder if you can make a tutorial about it or just give the steps you follow, Ireally appreciate that…Thanks and sorry for my English, I hope you understand what I tried to say.
Peace!
37. egy on November 27th, 2012 9:20 am
i like that..
38. Van Ryan on December 19th, 2012 4:59 am
Hi sir! great work on this! really made me want to relearn sketch up… and finally start to understand v-ray.
I am a 3ds max and mental ray user, and this quality of work would usually require a 20-45 render time.
I would simply like to ask how long did the render time took for this kind of great quality.
Thanks,
Van

Do you have the Vray program to send me?

Hello,awesome and helpful tutorial! Thanks!
But i have a problem. All my lights dont work (spotlight, omni, rectangle…) Tested different settings, changed values – nothing.Only can see lights from emissive materials when start render.How to fix this?
sorry for my english.Thanks
42. holando27 on March 16th, 2013 4:34 am
is the lampshade some kind of component or group??can you explain it more?
I can’t understand about mat 2sided.
thx for your answer & tutorial
regards,
43. admin on March 21st, 2013 10:57 am
@holandoI believe Nomer used a component for the lampshade and the mat2sided means the material is placed on both sides.
44. holando27 on March 23rd, 2013 5:32 am
@adminthanks a lot.. now I understand
maybe this link can more help about mat2sidedhttp://sketchupvrayresources.blogspot.com/2011/08/tutorial-how-to-simulate-lampshade.html
nice tutorial
Got something to say?
