In this exercise, you create several basic materials in V-Ray and explore material properties and options.

Part 1:

  • Create a simple composition of 5 objects.
  • Follow V-Ray 8.1 [basic options] to create basic rendering settings for your drawing. Please also select 640x480 as your output size in the Output section of the Render Options Window. Uncheck the Show GI Only box in the Lighting Settings of the Global Switches (you will establish a directional light in step 4).
  • Follow V-Ray 8.5 [infinite plane] to create a V-Ray Infinite Plane below your objects
  • Create a basic directional light (Rhinoceros 5.17 [directional light]) to highlight your objects.
  • Establish a saved (named) perspective view of your 5 objects, all objects must be visible. (Rhino 5.28 [saved views])

Part 2:

  • Follow V-Ray 8.2 [assigning materials] to assign a basic default material to all of your objects.
  • Follow V-Ray 8.3 [basic materials] to create and assign different colored materials to each of your objects. Perform a rendering of this view (showing 5 objects with 5 colors). You will post this to the course website.
  • Next, adjust the transparency of two of the objects (one should have a transparency color of “Dark Gray” and the other should have a transparency color of light gray). Perform another rendering of the same view. You will post this rendering to the website as well (in the same Exercise 204 post).
  • Next, Follow V-Ray 8.4 [reflection layers] to add reflection layers to 4 of the 5 materials. Create another rendering to post.
  • Edit the reflection layer’s Fresnel IOR for 3 of the 4 materials above. Perform another rendering and make a note of how this changes the appearance of the material. You will post this to the website as well.
  • Change the reflection glossiness on one of the above materials to 0.5 and the reflection glossiness on another to 0.75. Perform another rendering.

Part 3:

  • Optional: In this course, you will find that you need a variety of materials. I have an archive of materials available for you to download on the course website. Please download the .zip file (http://www.digitaltoolsforarchitects.com/resources/resource-packages/) of V-Ray materials and extract it to the resources folder on your flash drive.
  • Optional: Follow V-Ray 8.12 [importing materials]  to import at least 5 materials to your current scene.
  • Assign 5 materials to the 5 objects.  Perform another rendering and save the result.
  • Open your .3dm file from the last class (Exercise 203). Assign materials using the techniques learned above. Make sure to add one infinite plane below your objects. Render the result and post this, along with the others to the course website by the end of class today. You do not need to comment on this exercise.
    • Note:  Since you will be posting several images today, consider using a slideshow or gallery format for your post, see instructions below.

Uploading a Gallery:

  • Create a new post on the course website by clicking on the black "+ New" button at the top of the page.
  • Click on the "Add Media" button.
  • On the left side click on "Create Gallery" (red rectangle below)
  • Click on Upload Files and select the files to add to your gallery.

  • Click the "Create a new gallery" button at the bottom of the window (orange rectangle above)
  • You will now see the "Edit Gallery" window.  Please change the gallery settings to match the image below.  You can drag the images to change the order of the images.

  • Click on the "Insert Gallery" button at the bottom of the window.
  • You will see the images you just uploaded as a grid in the body of your post.
  • Change the Format to be "Gallery" and turn on the toggle for "Slideshow on Post page"

    • You can now set a featured image (just pick your favorite image) for your post and then publish your work.
