In this exercise, you will work with the building you created in Exercise 214. You will isolate the building and assign appropriate materials. You will then bring the building into an existing scene (San Francisco) and create a sunlight and sky system for lighting. You will render using a physical camera to control the results.

Part 1:

  • Open your Exercise 214 Rhino file. Select your best skyscraper (or the one you wish to work with). Use Edit>Copy to copy the building and then create a new Rhino file and use Edit>Paste to put your building in the new scene. Save this .3dm file. You will assign materials here and use this as a block for future work.
    • Note: You can always come back and edit this building by opening this file. When you save it, you will be able to update it in other rhino files where you have used it.
  • Remember to organize your layers for this block (and assign material by layer) to make the import easy.

Part 2:

  • Download the [Premium Content - Login] [Membership Options].3dm file from the course website (look for this exercise).
  • Place your building from Part 1 as a block reference into this SF downtown scene. You should see a blue foundation to help you orient your building (the foundation is 100’ x 200’).
    • Note: Rhinoceros will likely ask you to overwrite your existing scene materials, say ok to this.
  • Assign a white or light gray material to the SF City backdrop buildings. (I like White Porcelain for this).

Part 3:

  • Follow V-Ray 8.17 [sun] to establish a physical sun for your scene.
  • Note: the physical placement of your sun in your scene does not change the lighting in the scene. I typically put the sun at 0,0,0 to make it easy to find at a later time.
  • Now follow V-Ray 8.18 [sky] to create a sky for your scene.

Part 4:

  • Follow V-Ray 8.19 [physical camera] to set up a proper exposure for your new scene. Perform a rendering of your scene. If you are unhappy with the end result, change as necessary and repeat.
  • Post your work to the course website by the end of class today. You should comment on other students’ work for this exercise.
