IES Lighting Tutorial for Vray and 3D Max

A basic downloadable file (including model and lighting) and tutorial exploring the various ways you can light a scene through IES Lighting within Vray and 3Ds Max. Just follow the steps below.

Beginning

When wondering around 3D sites as Evermotion, Ronenbekerman, CgArchitect and others, I noticed that the majority of render images tend to use IES lighting. IES lighting just seems to add much more life than the simple lights available in Vray.

The present tutorial will show you how to set up a IES in Vray and Render it, adding those stunning light effects to your images. I will set up a simple tutorial, that won’t go into too much depth but will allow you to set up a quick IES light within your model.

The model I have supplied is a simple on that I have modeled in Sketchup and brought into 3D max, it is of a project we are working on for a hairdresser. It is a simple clay model that has been attributed a Vertex Edges Material (which I will get into later).

You will need to download two things:

IES Lights – available here

IES Light Viewer – available here

IES Generator – available here (not necessary to install)

 

What is IES Lighting

IES stands for Illuminating Engineering Society. IES standard file format was created for the electronic transfer of photometric data over the web. It has been widely used by many lighting manufacturers and is one of the industry standards in photometric data distribution. An IES file is basically the measurement of distribution of light (intensity) stored in ASCII format. You can think of it as a digital profile of a real world light. In 3d software like 3ds max it can be used for creating lights with shapes and physically accurate form. (Source cgarena.com)

 

SketchUp Importing to 3D Studio Max

I tend to model simple things in SketchUp, just because of its ease of use and also speed, it handles the job for the majority of things that I do.

You should verify that before exporting all your model has its faces facing front (white colour instead of blue) This will guarantee that there won’t be any problems in the rendering phase once we get onto 3D Max

I have ignored the chandelier back faces, as these are just simple front and back face

Export with the settings in image.

 

 

Inserting a IES Light

First thing you should do is download IES lights from www.lithonia.com , it has an extensive library of IES files with different categories.

After you have downloaded the lights, you can use IES viewer to browse through them and choose one from the preview.

Load up the file and insert a Photometric – Free Light (can use target light is you need to target it)

I have highlighted in red the changes I made:

Firstly turn on VrayShadows – Choose Photometric Web from Light Distribuition pull down menu and then change your intensity according to what you desire.

Note that you can change the area shadows, so that you may have a softer shadow around the projected shadow edges.

This will get you started on your way to using IES Lights

 

Wireframe Tutorial Vray

I have used a wireframe type material, which I like to use in these clay render type solutions, so that provides a nice “work in progress” image, so we can analise what needs to be twequed and adjusted.

Just insert VrayEdgesTex into the diffuse slot of a VrayMaterial and voila, as easy as that. Now all you need to do is insert that into the Override Material in the Render Setup box.

Hope you have enjoyed this first simple tutorial and that if you have any doubts please feel free to leave a comment.

    Hi , that was a good tutorial , but there are an issue on the tutorial images. Can’t see the wording and numbers on the screen or downloaded as picture.

  3. by Juni

    Very good lighting, thanks for the useful lesson

  4. by Vince Jaramillo

    why use MAX’s default Parametric light? Why not the Vray IES option?

    Vince

    • Hi there Vince,

      thanks for your comment, this is quite an old tutorial and at the time, I was doing this type of lighting in this way.
      At the present I only use Vray lighting actually and do all my IES in post, but when I do have to use IES for some reason I would use your Vray IES option.

      Cheers
      Pedro
