This is one of my architectural Visualisation jobs and also my first experiment with V-ray, before that I did everything in Mental Ray, it took me 4 hours to model everything in the scene, 1 hour to calculate indirect Illumination and 30 minutes to render, I would really love to hear some feedback about this one :)
Also, here's a wireframe of this scene:
To light up this scene I've used 3 lights: 2 v-ray lights at every window and one target directional light as a sunlight.
Settings for V-ray lights are:
1. Invisible
2. Store with Irradiance map
3. Multiplier - 15
Settings for Target Directional Lights:
1. Shadow: V-Ray area Shadow
2. Multiplier: 0,5
3. Hotspot/Beam and Fallof/Field: 5m
V-ray Render Settings:
1.Indirect Illumination:
Primary Bounces - Multiplier: 1.1, Irradiance Map
Secondary Bounces - Multiplier 1, Light Cache
2. Irradiance Map
Current Preset - Medium
3. Light Cache
Calculation Parameters - Subdivs: 1000, Sample Size: 0,02
4. V-ray Environment
GI Environment - Override Max's: checked, Multiplier: 1, Color: White
Reflection/Refraction - Override Max's: checked, Multiplier: 6, Color: White
5. rQMC Sampler
Everything Stays Default, apart from Noise Treshold, it was set to 0,05
6. V-ray Color Mapping
Expotential
