I am using the compositor to add fog effect to a scene I want to use for a skybox. To create the skybox texture, it is possible to render six planes separately (set camera to 1:1 aspect ratio 90 deg fov), but that is a lot of work. Or maybe there is another way to fade out distant objects.

  • $\begingroup$ If you are in cycles perhaps use actual geometry with a volumetric material to make the fog and simulate distance fading? $\endgroup$ – Duarte Farrajota Ramos Jan 18 '17 at 3:55
  • $\begingroup$ @DuarteFarrajotaRamos Good point, but I always get the scene to dark, and it increases the render time alot. $\endgroup$ – user877329 Jan 18 '17 at 11:07
  • $\begingroup$ If it is too dark then it's probably because it is too dense, never really tried it myself, but for fog I think it has to have really low density value. As for render times not really much one can do, maybe exclude fog effects from everything except camera visibility. $\endgroup$ – Duarte Farrajota Ramos Jan 18 '17 at 13:53
