Observe, Observe, Observe. Wherever you are, whatever you are doing, become aware of how your surroundings or what you are viewing are lit and what kind of feeling or mood that lighting may create.
When it comes to lighting a 3D-scene, the light-setup can either make or break the scene’s believability and realism. Many artists lack the knowledge of lighting techniques. There are three concerns you have to consider during your lighting-setup: Is there enough light? Is the light source believable? And, how does the lighting affect the mood of the scene?
In this tutorial, we will illuminate the scene with the help of one light source and one HDRI. This is a step by step tutorial, with images to grasp the general workflow idea easily.
First download the 3d file from here and textures if you do not have one of Hyperfocal Design HDRI Skies you can also use their free HDRI samples from their website called www.hyperfocaldesign.com/free-textures/
Step 1: Open the 3d model in max and apply the materials to the model. You can see the screenshots for reference.

Direct Lighting Setup
We create a direct light with Vray Shadows. You can follow the images. But it really is a matter of taste. I like seeing walls washed with a combination of light and shadows. 
Use areas shadows this provides strong but dispersed shadows. Play with the UVW size in Vray Shadows Params. You can see the images below.
The first image has a value of zero (size UVW) giving it a focused look with no fading. If you increase the size, you can see there is now some fading in the shadow borders. And finally very dispersed shadows.
HDRI Lighting Setup
Now we load the HDRIs into the material editor; one for the illumination and other for the Environment.
Rendering and G. I Check out the rendering settings through which I achived the interior lighting. And Hope you enjoyed this tutorial and if you have any queries or suggestions then please mail me.
