QUESTION
How do you get glass to cast a shadow?

ANSWER
A glass object will cast a shadow when you:
  • Use the PureGlass Material.
  • Set the Opacity slider value higher than 0.
  • Render the image in 5-star quality.
There are 16 shades of grey for PureGlass shadows - one for each sub-frame that a rendering consists of.

Bear in mind that you can't preview PureGlass shadows in Build Mode.


   
   
Compare These Two Renders:
  • Render at 3 Star Quality - No Shadow - No Reduced Light Through the Glass

   
  • Render at 5 Star Quality - Shadow/Reduced Light Through the Glass
