• Type in sun in the command line and choose SunDockBar
• You can also access this command from the VRay interface sun icon
• Turn the sun system on and select the location and time/date of your scene
• Once you have selected these options, hit OK and place the sun/light within your model

• Turn on the physical camera and adjust the shutter speed and Film speed ISO
• For a daylight scene with the sun being the only source of light, your shutter speed value should be around 300-500 (depending on the daytime in the sun settings) and the ISO should be around 100-150 .

• Your result will look like this.
• The scene looks a bit too yellow. In order to adjust that, select a slightly yellow color in the white balance box.

• Your new result will be this:

• Connect your sun to the environment of the scene
• Go to Environment , click on the m next to GI and Reflection/refraction (background) and connect the sunsystem to the environment by selecting TexSky on the left side first and then choosing Rhino Document Sun on top

• Your result will look like this.
• Adjust the white balance to a more blueish tone and correct the shutter speed as well as the ISO value.

• In order to get the most realistic light calculation you should change your primary engine to irradiance map and the secondary engine to lightcache in the indirect illumination menu .

• After adjusting the engines turning on the ambient occlusion and a blueish tone for the white balance, the shutter speed of 600 and the ISO of 100. Your result will be this:

• In order to get softer shadows from your sun you can increase its size in the environment menu:

• With a size value of 10 your scene looks like this:

• Now you have a nice lighting set up. In order to get a realistic result you have to add some textures. Use the Vray material editor in order to load some materials and apply them to the surfaces:
