I would like to save my physics animation in a PNG sequence with the landing plane transparent. I have an object that is landing on a plane. This plane needs to be transparent in the PNG animation sequence. I've seen posts with the "Film" tab, but I don't seem to have this in verion 2.79a. How do I do this? Thank you.

  • $\begingroup$ As stated, I don't have the "Film" tab. That post refers to an older version, I'm assuming. $\endgroup$ – Matt Mar 18 '18 at 0:45

    $\begingroup$ Yes you do. You are either not looking in the right place or have the wrong render engine active. If you don't then edit your question and provide screenshots to back your claim so that we don't have to guess in the dark what your issue is. $\endgroup$ – Duarte Farrajota Ramos Mar 18 '18 at 0:51

Film tab appears with Cycles Renderer (here v2.79a): enter image description here

The "Transparent" option in Film tab is for the background only. For any mesh to be transparent as well, you have several options. Make sure you select RGBA in the PNG options in order to include the transparency.

  1. define the material to be transparent: enter image description here
  2. uncheck the object from rendering: enter image description here
  3. make it invisible to camera: enter image description here

I am sure I am missing some other means! Note that all those methods may have side effect like shadows etc.

  • $\begingroup$ Awesome, but how does it distinguish which Plane is transparent? $\endgroup$ – Matt Mar 18 '18 at 2:04
  • $\begingroup$ See, one of the Planes is the "ground" of my animation, which includes gravity. The objects fall and bounce on the Plane. I need that Plane to be transparent for the PNG animation sequencing. $\endgroup$ – Matt Mar 18 '18 at 2:06

  • $\begingroup$ Sorry, but that's just making the plane gray. $\endgroup$ – Matt Mar 18 '18 at 3:06
  • $\begingroup$ Is there some way I can save this project and let you download it to take a look to see what I am missing? $\endgroup$ – Matt Mar 18 '18 at 3:08
