In this exercise, you will create a high-quality V-Ray rendering of an exterior perspective. You should use your model created in Exercise 218 & 219. Please note, as many of you are still working to design your retreat, I have given you another day to work. The steps below are similar to Exercise 220 and if you completed them already, just perform a rendering for today after you spend the lab working on your design. If you did not complete the steps below as part of Exercise 220, you should do them today as part of Exercise 221 and post your work.
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 Lens Length. This will enable you to drag and adjust the lens 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. (I like 28)
- Follow Rhino 5.28 [saved views] to save your view. Name this view “Render01” or something similar.
Part 2: Establishing an HDRI environment
- Follow V-Ray 8.24 [HDRI] to set up an HDRI image environment for the GI (Skylight) and Background.
- Follow V-Ray 8.25 [channels] to add channels for rendering. (Add Z-Depth and Alpha)
Part 3: Assigning a V-Ray Sun System
- Follow V-Ray 8.17 [sun] to establish a sunlight system.
- Follow V-Ray 8.19 [physical camera] 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 8.26 [HDRI + Sunlight] to adjust the HDRI image to match the physical sun created in step 5.
Part 4: Assigning Appropriate 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.
Part 5: Ocean, Grass & Rocks
- Using the skills you have learned previously in the semester (V-Ray Proxy objects) and the strategies demonstrated in lecture, add water, rocks & grass where appropriate to enhance your design. (Some landscape objects are here)
Part 6: Final Rendering(s)
- Perform your final rendering at 1024 x 768 minimum. You may elect to render at a larger size, but be aware this can take more time. You should use the network (distributed) rendering for this operation.
- You should also navigate to the Output drawer of the V-Ray options and check the box to “Save Render Output” and “Save Alpha Separate.” Make sure to click the button with the ... and save your work to your OneDrive folder (if you are using OneDrive).
- 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.
