In this exercise, you will work establish an exterior night perspective/rendering. You should consider adding both interior and exterior lighting to the scene and control the output of the lighting. You will also install and use a night sky HDRI background.
Part 1: Setting up your view in Rhinoceros
- Follow Rhinoceros 5.28 [Saved Views] to set up a third named view of your exterior. You may wish to change the lens length down to 18(mm) to mimic a wide angle lens camera. This can be the same view you established for your exterior rendering or you can pick a new view.
- Make sure your scene has appropriate materials assigned. If necessary, adjust texture maps to make materials have appropriate scale.
Part 2: Night HDRI
- Follow V-Ray 8.24 [HDRI] & 8.26 [HDRI + Sunlight] to install a night HDRI (Download .hdr file from the course website or use your own). Set the value for the GI and Background to be 1.0. You may need to turn off you sun as well (or at least decrease the intensity to 0.1).

Part 3: Adding Lights.
- Identify 2-4 exterior places where you would like to add lights to your rendering. You may need to create geometry to hold the light. You can make this geometry as a block reference (Rhino 5.14) so you can use it later. (You may have done this in Exercise 223 & 224, but review light locations and modify if necessary).
- If you can see the light source (i.e. a bulb, neon, etc.) then you should create and use an emissive material (V-Ray 8.15) to represent the bulb. Note: Turn the intensity up to 65 so that you can see the bulb in your rendering.
- Place your light geometry in the scene.
- Using settings similar to those used in Exercise 223 & 224, create spotlights or point lights as appropriate for each fixture in the interior/exterior night rendering.
Part 4: Save Your Rendering(s) and Channels
- Follow V-Ray 8.25 to turn on the “Reflection” and “Refraction” channels in addition to the Z-Depth, Alpha & Background.
- Perform a final rendering. Ideally the final rendering would be 800px or larger along the larger size though this will depend on the time remaining in lab.
Part 5: Finesse & Final Image
- Post your work to the course website by the end of class today. You should comment on 3 other students’ renderings for this exercise. Next week you will continue working with V-Ray for your final project.
