Rendering an Exterior Perspective
In this exercise, you create a high quality V-Ray rendering of an exterior perspective. You should use your model created in Exercise 11.3
Part 1: Setting up the “Ideal View”
- When you begin setting up this view, think as though you were a photographer trying to showcase a “real” building. Think about your composition of the final render as well as the design it showcases.
- Note: You can adjust the lens length of the viewport camera by right clicking on the view label and selecting Set Camera>Adjust Lense Length. This will enable you to drag and adjust the lense length. Alternatively, you can specify the lens length at the same time by looking at the properties window and editing the “Lens Length” value. A good “architectural” lens length is between 18 and 35.
- Follow Rhino Tutorial 5.28 to save your view. Name this view “Render01” or something similar.
Part 2: Establishing an HDRI environment
- Follow V-Ray Tutorial 8.24 to set up an HDRI image environment for the GI (Skylight) and Background.
- Follow V-Ray Tutorial 8.25 to add channels for rendering.
Part 3: Assigning a V-Ray Sun System
- Follow V-Ray Tutorial 8.17 to establish a sunlight system.
- Follow V-Ray Tutorial 8.19 to set up a physical camera to properly expose the scene. You may wish to start with a shutter speed value of 100 or 200.
- Follow V-Ray Tutorial 8.26 to adjust the HDRI image to match the physical sun created in step 5.
Part 4: Assigning Appropirate Materials
- Spend some time assigning materials to your model. Make sure to adjust the mapping on objects to have the material applied correctly. You may use materials you find online (either the digital tools site or outside sources) or you can create your own. (Review HBAw13 for help)
Part 5: Final Rendering(s)
- Perform your final rendering at 800 x 600 minimum. You may elect to render at a larger size, but be aware this can take more time.
- Make sure to save .jpg or .png files for each channel you create (RGB Color, Alpha, Background, & Z-depth). You will need these files next Monday.
- Post your final RGB color image to the course website by the end of class today. Please comment on at least 3 other students’ renderings before the start of next class.
