I tracked a 17 second video where I had a bunch of dots on a macbook. I want to make it look like there is shattered glass in front of the mac. Currently working on concepts, I ran into a problem: The background video does not render in the final render (It does in the viewport render) (I'm using Cycles)

This is what it looks like in viewport render: All of the pillars are made of glass, with an IOR of 1.1 and 0 Roughness.

Some people online say to enable/disable transparent under film.

With transparent on (F12 Render)

Without transparent on (F12 Render)

Here's my Background settings:

Then my render settings:

  • $\begingroup$ @cegaton any tips on doing this easily? Properly scaling it to the camera doesn't sound like fun $\endgroup$ Oct 7, 2016 at 16:05
  • $\begingroup$ blender.stackexchange.com/questions/38452/… that will make your background image render behind the 3d scene... but to make the glass interact with the screen, the screen itself has to be an object in the 3d environment. $\endgroup$
