In this tutorial, we’ll be using real units, so the first thing would be to open the menu "Customize > Units

Setup > US" and choose "Standard > Feet w/Decimal Inches" as the unit.

Step 2

When you are trying to get a photorealistic quality it is very important to make sure that your object

scale is accurate. This will play an important role in achieving a good render. Also, as you can see the scene is quite simple... just a small lobby (mostly modeled with boxes). Note: It is important that it is a

closed room, and there are no openings for the light from environment to enter.

Step 3

Press f10, and from the "assign renderer" tab choose "Vray". This will enable "Vray" as your renderer, and also enable Vray materials in your material editor.

Step 4

Assign a simple Vray material to all the objects in the scene, and set up basic scene lighting and render settings. This is to finalize the lighting and render settings and save time, since a plain material renders

much faster than reflective and glossy materials which will be added later.

Step 5

Now to work on the lighting and render settings to achieve the final result.

Step 6

Add a Vray physical camera to the scene by going to "Create Tab > Camera > Vray > Physical Camera".

Step 7

The settings for a physical camera are:

Type - Determines the type of the camera. Set it to "Still".

Film Gate - Specifies the horizontal size of the film gate in millimeters. Set it according

to your scene.

Focal Length - Specifies the equivalent focal length of the camera lens.

f-number - The width of the camera aperture and (indirectly) exposure. If the

Exposure option is checked, changing the f-number will affect the image brightness.

Vignetting - When this option is on, the optical vignetting effect of a real-world

cameras is simulated.

White Balance - Allows additional modification of the image output according to the

color or preset chosen.

Shutter Speed - The shutter speed (in inverse seconds) for the still photographic

camera. For example, a shutter speed of 1/50 s corresponds to a value of 50 for this

parameter.

Film Speed (ISO) - Determines the film power (sensitivity). Smaller values make the

image darker, while larger values make it brighter.

Step 8

Now to place the various Vray lights. Lights 1-4 affect the scene directly, whereas light 5

has been placed in a downward direction, and will affect the scene in an indirect (in the

form of bounced light).
