In this exercise, you will work to establish an interior 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 [named views] to set up a third named view of your interior. 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 an appropriate scale.
- Note: You should perform a File>Save As... before continuing with this exercise. You should also switch your glass material from being the highly reflective material used for your day exterior rendering and instead use a more conventional glass material. (V-Ray 8.14 or download “Basic Glass” from the course website)
Part 2: Night HDRI
- Follow V-Ray 8.24 [HDRI] & V-Ray 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 your 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 [blocks]) so you can use it later. (You may have done this in Exercise 219 & 221, but review light locations and modify if necessary).
- Note: Before changing V-Ray settings, save your .visopt file so that you can return to your daytime settings and do additional renderings.
- 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 [emissive material]) to represent the bulb.
- Note: Turn the intensity up to 100 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 219 & 221, create spotlights or point lights as appropriate for each fixture in the interior/exterior night rendering.
Part 4: Save Your Rendering(s) and Elements/Channels
- Follow V-Ray 8.25 [channels] 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 (for the long side) though this will depend on the time remaining in the 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.
