Atmospheric perspective with Ai Fog

- [Instructor] To begin the chapter on rendering…let's add a simple fog atmosphere to this exterior shot.…The effect we want to achieve is atmospheric perspective…where objects in the distance are lower contrast…due to atmospheric scattering in the air.…Let's render the camera view,…clicking it to give focus.…And go to the menus and choose Arnold, Render.…The Arnold render view shows…the exterior scene with no fog applied.…Now open the render settings.…

You can do that from status line.…Render settings…and then the Arnold render tab…Open up the environment section.…Inside here, you'll see two slots for maps.…The background legacy slot…is only there for backward compatibility…with pervious versions of Arnold.…We don't need this background field anymore…because the skydome light does everything we need.…We want to apply an atmosphere here to the scene.…

So click on Create Render Note.…And from the pop up dialogue choose…Create AI fog.…The fog's created.…We want to select the AI fog.…It looks like it is already selected.…
