IES Light Tutorial using V-Ray for SketchUp

nomer-start

By Nomer Adona

V-Ray for SketchUp (ver. 1.48.66) has the new added feature of IES Lights and Spotlights. V-Ray works within the SketchUp environment allowing users to be able to efficiently incorporate the task of rendering within their current workflow. IES (Illumination Engineering Society) is a standard digital file in ASCII format, which measures the distribution of light, in other words the intensity of the light and its shape. Lamp manufacturers create these files for accurately simulating their lights and now we have the ability to add IES profiles (for light accuracy).

I have a new second tutorial, just published called Basic IES Light Tutorial using V-Ray for SketchUp. I use V-Ray release version 1.48.90 in it, which is a much better and  stable release.

nomer-tut

In this simple tutorial we are going to set up three basic pin lights using imported IES files. You can download IES files files of your own choice from here GE Lighting and more here IES Maps and a SketchUp light fitting here. More IES files here if those don’t work for your particular version of V-Ray.You can also download the GE Light*Beams 3.0 software at the bottom of this page. Its a powerful lighting design aid for GE directional reflector lamps. Included is a complete database of IES files for current GE products. Another collection of IES files can be found in the links below:

Here is the room set up. A simple box with 3 pin lights as shown in the image below.

Follow the steps highlighted in the following images below.

Step 6

And here is the render where I used 3 different types of IES light data. You will see the rendering time using default setting with no sky and no physical camera, the rendering time is just 14.7 seconds. You can also see the difference in the spread and intensity of the three lights.

I hope you enjoyed this short tutorial and find it useful in your future projects.

Check out my second tutorial on IES lights (Basic IES Light Tutorial using V-Ray for SketchUp) which uses a less ‘buggy’ release version of V-Ray for SketchUp. Also here is another short tutorial on using IES lights in a 3ds Max work flow, may be useful in helping you understand the concept and use.

Thanks

    is it a plugin ?
    where i can find it ?

  8. admin on June 9th, 2010 11:28 am

    @daniel,Jonny,dewa… IES lighting is a new feature that comes with the latest version (ver. 1.48.66) of V-Ray for SketchUp.
    @ deepak…while the IES light is chosen, right click and select ‘edit light’. Under ‘Sampling’ browse for the file to load it.

  9. Edwin on June 17th, 2010 5:31 pm

    I still dont get the no.4 step.. where is the ‘sampling’ folder? i couldnt find it.. or should we download first?

  10. admin on June 18th, 2010 12:53 pm

    @Edwin… yes then browse for it on your computer where you downloaded it too…

  11. Duu on June 23rd, 2010 3:26 am

    Sir, where can I get the IES file?

  12. admin on June 23rd, 2010 12:54 pm

    @Duu You can get them here http://genet.gelighting.com/LightProducts/Dispatcher?REQUEST=IESCATEGORYPAGE and
    http://www.4shared.com/file/200355919/ecaf3710/IES-mapas.html and http://www.4shared.com/file/200356156/4da11d3/IES.html At the end of the first paragraph there are links to them!

  13. brigitta heni on July 28th, 2010 5:19 pm

    thank you for your information. i need your help because i’m just student now..

  14. sergio on September 16th, 2010 12:44 am

    for future amateurs of vray for su: GE ies files didn’t work with my vray 1.48.89 so i thought that these ies files may be wrong and tried these ones http://www.lithonia.com/Photometrics.aspx . works like a charm.

  15. admin on September 16th, 2010 11:18 am

    Thanks Sergio for the link, will add it too the tutorial…

  16. chrisler on September 23rd, 2010 4:24 pm

    Thanks for these helpful hints with regard to IES, I would just like to ask if this V-ray for sketchup ver.1.48.66 could be used both for Sketchup 6 and Sketchup 8? And if they would be possible is it now ready for them again to be installed with the IES files after? Thanks, I hope you could help me be cleared with these.

  17. chrisler on September 23rd, 2010 7:22 pm

    I would like to ask as well with regards to step no. 4, as I couldn’t find the Edit Light command sampling folder for me to upload the IES light that I have already downloaded on my computer. Again thanks.

  18. nomeradona on September 25th, 2010 2:07 pm

    @chrisler…et al. I wonder why lots of people are having difficulty with Step 4. All you have to do is click on the small box on the right of that box and browse the location were you saved the IES file on your computer.

    IES file sometimes have different values. I like those lights from lithonia and General electric. Some of the files available in the net are not true IES data, therefore i encourage you to play on the multiplier until you get the desired effect.

    cheers

  19. Michal on September 29th, 2010 11:31 am

    I’ve tried to render example from this tutorial.. and I have only black picture rendered…. I’m using Sketchup 8 and V-ray 1.48.89, anyone can help me ?

    cheers

    Michal

  20. admin on October 2nd, 2010 4:49 pm

    Hi Michal
    I would ask this question over at the V-Ray Forum, here is the link http://forum.asgvis.com/index.php?action=forum. There is a ‘V-Ray for SketchUp General’ sub-forum, ask there. SketchUp 8 is still relatively new so there may still be some little bugs when working with other software. I am sure they will know what is happening with ver. 8 and V-Ray….

  21. Scotty on October 19th, 2010 6:24 am

    Hi Nomeradona,

    thanks for this tutorial. I hate to be critical of anyone who makes the time and effort to educate those of us who are less knowledgeable on a product, but this tutorial could be a lot more helpful.

    With respect, this tutorial only shows how to ‘build’ the example shown. Personally, I would like more info on what the power setting range is. You use 5,000,000. I have no idea if this high, low or somewhere in between. Could you clarify what useable range might be and how one determines what setting to use. Also there are links to a number of very resource full sites containing IES files. I have no idea what ones to use (what is ARCHITECTURAL ARM-MOUNTED CUTOFF LUMINAIRE WITH SR3 REFLECTOR, BLACK INTERNAL HOUSE SIDE for example????). Is there a simple way to identify IES files for a particular application (interior / exterior / narrow beam / wide beam etc)? Also, you have used an IES file in the tutorial but not told us which one.

    Finally, you say to scale the light but, again, not provided info on how to do so in detail.

    I hope I am not being unfair. I have learnt so much from your tutorials but this one could do with a bit more!

    Cheers…Scotty

  22. chrisler on October 24th, 2010 3:16 pm

    Hello.
    Could you please help me; even though I was able to install the Vray w/ IES and was at first able to render some of my works which I was trying to practice with but after some few more rendering practice with the same model, my sketchup would no longer render. The frame buffer no longer shows and after choosing the render icon it will have a prompt w/c would just say that the Vray is under process and that I’ll just have to wait and then after that it would just return to the previous command without my work being rendered? Please could you assist me on this? As I don’t know what shall I do. Hoping that there would be prompt answer to this query of mine. Thanks a lot

  23. robert on October 28th, 2010 8:15 pm

    hello,
    is the receptacle really needed to to obtain the effect?,

  24. robert on October 28th, 2010 8:34 pm

    i down load the ies skp, and tried out all on the tutorial, but the light doesnt come out in the render, unlike when im not using any receptacle, only that i dont have the effect as you shown in this tutorial… im lost.. pls. help, tnks.

  25. nomeradona on October 30th, 2010 7:09 am

    hi guys,

    first of all my apology for not coming back here often…

    just a context.. I have done this tutorial when 1.48.66 was released. this version was a little bit buggy and until now, asgvis is trying their best to come up with a better and stable one. I believe from 1.48.91, everything became much better. I will look again this tutorial using the latest build 1.48.95 and will give you a much better picture. i will also supply the ies file that i will be using here together with the file so you can do and check it on your own.

    there are some important steps that must be considered with IES with vray. I have also send these concern to asgvis particularly with the question of how come we need to create a million numbers to see the effect of ies.. so one answer was the IES should come out from reliable source like Lithonia.

    another thing to know is that you should turn off the vray sun and vray physical camera. vray sun is a big omni light and the vray physical camera is a counter balance to correct the exposure. because of this. the light intensity of all lights ( omni, rectangular and ies) were all affected when using vray physical camera. I found out by turning the physical camera off and sun, I remove the burden of playing the balancing act with my physical camera. now you can only concentrate on the intensity of your lighting (in this cas ies lighting).

    as for the question of robert. You can actually have the same effect whether you put the ies inside the receptacle or not. the idea of using the receptacle was to ensure that observer can see the light source.

  26. Pablo on November 2nd, 2010 1:45 am

    Nomeradona! Can´t adjust the value on the power value in Edit Light dialogue box. Where ypu put 5000000, It only allows me to type zeros but no other number on the box……………… Help me please!

  27. nomer on November 12th, 2010 9:13 am

    Pablo, that must be a bug in your version. what version are you using? Can you read my latest tutorial on this.

  28. vida on December 29th, 2010 4:31 pm

  32. Abhimanyu on April 28th, 2011 11:36 am

  34. Lilo22 on May 19th, 2011 1:37 am

    Hi Nomeradora
    I’m working in a window display project for a store and I’m just getting started in this… I have problems with the lighting of my project and I’ve read thousands of tutorials but all of them seem so difficult to me. Then I found yours and I found it very practical and easy, i understood all the process and I did it in my project but for some reason it doesn’t work! All I have to do is to make a simple spotlight but when I render it doesn’t show any lights at all, and I turned off physical camera as you said and still nothing. Please help me with this, I’ve tried to figure out what’s wrong but still have no clue. Please contact me, my email is lgonzalez182@hotmail.com

    Thank u

  35. dwing on August 31st, 2011 5:42 pm

    the light ies is too big….the intensity is out of scale..please help sir..thanks! cheers for your tutorials…

  36. cesar_agp on September 6th, 2011 5:47 am

    Hi, i’m new using vray for SU and i have a problem to see the IES lights in the render… I download several .ies samples from diferents web sites, I increment up to 50,000,000 the power, and still not working.
    I´m sure that the problem its simple but i cant fix it.

    kind regards

  37. e.b on September 9th, 2011 9:18 pm

    where i can find the ies file

  38. pi on September 10th, 2011 3:37 pm

    hii…
    when i choose this link : http://genet.gelighting.com/LightProducts/Dispatcher?REQUEST=IESCATEGORYPAGE , i still can’t understand where i can download the ies file :'( Can u give more specification step about that?? i think that would be more easy if you enclose the image of that page (as u do for this page). sorry n thank u so much =)
    best regards

  39. ziad on September 13th, 2011 10:28 pm

    i followed your steps and just got a black image no light at all.

Got something to say?
