Hi guys. It seems that there are 2 modelling factors that people find more challenging: (a) the core shadow and (b) ambient occlusion. I'm posting a solution for those two modelling factors for you to consider. As far as the core shadow is concerned, it might be useful to think about it in the following way: if you take the shape of the form shadow and subtract the shape of the reflected light, you are left with the core shadow. Many of you correctly identified ambient occlusion where the monkey head touches the table / surface, but missed it in some other important places. Remember to look for it in cavities, tight corners, gaps and creases, like those found between eye balls sockets.

Overview

Let's practice identifying modeling factors!

Materials Needed

  • The project files
  • Either a printer and colored pencils 
  • Or your favorite image editing application such as Photoshop

Steps

  1. Decide whether you'll do this assignment digitally or traditionally, and download the project files.
    If you do it traditionally, you'll draw on the printout.
  2. Identify and label all modeling factors by drawing an outline for each of them and coloring in the area. For "Ambient Light Intensity", estimate a percentage. 0% is no ambient light at all, 100% is extreme ambient light Intensity.
  3. Upload your labelled image. 

Duration

This project should take 30–60 minutes to complete. Start with the sphere and if you want to challenge yourself, do the monkey afterward.

Example

Newest
ball light intensity: 50%, pig light intensity: 75%, Monkey light intensity: 25%
