TUTORIAL - Interior lighting set up - Vray 2.0

 Thanks again to Aleso for this tutorial

In this tutorial you will learn how to lighting and setting up a realistic render with vray 2.0 and 3ds max 2011, also how to use ies lights, setting lighting with vray sun and vray sky and using vray physical camera, and see how you can set up your render.

Soon i will upload a tutorial about modeling and unwrapping realistic furniture with 3ds max, zbrush and photoshop, but this times is just lighting and rendering.

This is the final render of this tutorial


To start i have used vray plane lights, vray sun & sky, photometric ies lights and vray camera, i used 3 plane lights for each window, all the lights have the same settings, you can see the settings in the right panel, this is how it looks from the top view


Also i have used vray sun and sky, and this is the position for vray sun and the settings

Now this it is time for the vray camera, and this is the settings of the vray camera.

In the indoor lighting i used photometric ies lighting with vray, i did not used the vray ies because the standard photometric lights has more customizable settings/parameters, all the photometric lights have the same settings, this is an screenshot of all the ies lights in the scene and the settings.

If you want to download the ies file that i used in this scene click here
And this is how the ies looks like

We are done with the lighting part here, let’s see the render settings, i usually use brute force, but in this time i was looking for some fast render times, and irradiance map + light cache is more faster than light cache + brute force, and this is the the render set up with vray

If you want to speed up the render time using this setting, go to the Settings tab, and in the Global Subdivision Multiplier change the 3 for 1. In photoshop i did a color correction, chromatic aberration and sharpen, nothing more :P
I hope that you have learned something and please if you have any question, just comment :D

    I mention this at the top of the blog post.

    Check it out, there are some great tuts there, however just looking through his comments the light cache setting are:

    "light cache settings, use between 1200 and 2000"

  3. great work. question-if i downsize the intensity of lights and vray sun,for not using physical camera for adjustinh the light, will i get the same results? i have trouble on using vray physical camera, especially with the f number that gives me the worst results when its too low. thank you.

  4. Yea the F number can be difficult, are you new to Vray? I used to feel the same about the Vray phys cams, however there are far more options available when using Vray cams to the standards., for example, realistic shutter controls, built in vertical and horizontal offset and shift, pre post exposure control. Good ISO control ability, as well as easily editable near and far clipping and horizon planes for generating good DOF control.

    I would recommend the vray cams over the standard max cams. To answer your question it can be possible to counter the intensity of a vray light by lowering the multiplier, however in doing this you will be effecting the colour balance and saturation of your image. I would try persevering with the vray cam if I were you, try holding the f number at around 6-8 and try increasing the shutter ISO the faster shutter speed should have an effect on your scene's intensity. Also have a look at a few photography websites, these vray cams behave very similar to real world cams.

    Hope this helps!

  5. yes im new to vray, its a couple of mounths tha im using it, i used to go with mental ray and iray. iray is easy to use because calculates the light automatically, is very slow though and has no materials.vray is fantastic because of his realistic results. thanks for ur advices,and for sharing ur knowledge,they are really usefull to me. one last question:
    In ur tuttorial you have windows only to the one side of the room, lets suppose that we got one more window to the other side of the room, opposite to those that the sun goes in, the multiplier of the vray light for that window will still be 100?(for a physically accurate result)if no, how much? thanks again!

    Check this guy out, some of his tutorials are fantastic! To answer your question, try out the lighting settings as is and see what you get, you may find that you do not need the multiplier levels of the first window to achieve a good result. You are probably looking for an ambient result from the second window, which will be achieved on the room by the GI pass of your scene I assume.

    anyway Good Luck.

  8. I am so disappointed, another tutorial with just great images but not the real settings! You must have other settings that you used for obtaining the results in the pictures you put here. I used step by step all the settings that you show here and my result is not even close to what you show here! So many tutorials with great pictures but none of them give you the real settings! This one is no different! So disappointing!

  9. Yeah...same here.
    Great image here, but if you do it yourself step by step...not even close.

    Apreciate the help, but a video tutorial is alot better.
