Introduction:

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:

  • 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.
  • Follow V-Ray 8.12 [importing materials]  to import at least 5 materials to your current scene.  Assign each to one of the 5 objects.  Perform another rendering and save the result.
  • Open your .3dm file from 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.

Posting a Gallery of Images to the Course Website:

  • Login to www.digitaltoolsforarchitects.com and create a new post. Give the post a title with your name and Exercise 204.
  • Select the “Exercise 204” checkbox from the “Categories” section as well as “Exercises” and “Digital Tools For Architects (Archi 136)”
  • Now change the “Format” to be “Gallery” (This should be directly below where you select “Publish” in the Format box).
  • In the “Content” Tab, check the box for “Slideshow on Post Page” then move to the Gallery tab.
  • In this “Gallery” tab, click on the “Add images to gallery” button below “Selected Images From Gallery” You should then navigate and select your images from your flash drive. You can do a multiple file upload, but be patient as it can take some time to upload.
  • Now click on "Insert Gallery Into Post"
  • Click on “Publish” to publish your post. You’re not done, continue below.
  • Set a featured image for your post by clicking the “Add Media” button. Click on the “Set Featured Image” link and choose “Images Uploaded to this Post” from the drop-down menu. Select your favorite image and click “Set Featured Image”
  • Navigate to the Gallery tab again and confirm all of your images have been uploaded. Click “Update” one last time and then view your post to be sure that your images load correctly.
