    $\begingroup$ Are you using Cycles or Evee? basically you need to render out a mask and use that in compositing to change the background. This is how you render a mask: youtube.com/watch?v=MDNi-NNSlyY And this node helps you extract your data in the compositor: docs.blender.org/manual/en/latest/compositing/types/input/… $\endgroup$ – morph3us Aug 20 '19 at 11:08
  • $\begingroup$ And before i extract the data in compositor i have to render my animation before ? $\endgroup$ – Krenk Aug 20 '19 at 13:59
  • $\begingroup$ What i should do first after creating the mask? $\endgroup$ – Krenk Aug 20 '19 at 14:02
  • $\begingroup$ you can either rerender the whole animation or just the alpha mask as a seperate layer, i presume. I wanted to push you in the right direction, but havent done something like that in Blender / Cycles myself yet, thats why I only commented and didnt give an answer. $\endgroup$ – morph3us Aug 20 '19 at 15:00

    $\begingroup$ I found that i can use an alpha over node in the compositor and then i just have to render the animation . $\endgroup$ – Krenk Aug 20 '19 at 15:11

You can change the color of the background in the compositor with the environment pass and either an alpha over node or a mix node.
