Add Physical Sky illumination and background.
- [Narrator] The Arnold physical sky environment…provides illumination and a back drop…through an Arnold SkyDome light.…The Ai physical sky is…a simulation that's photometrically accurate.…Let's go ahead and open up the Arnold Render view.…Arnold, Render.…And then create the physical sky…back in the menus Arnold, Lights, Physical Sky.…And we see something now in our Arnold Render view.…
There's a sphere at the origin.…That's an Ai SkyDome light.…Select it and we can see it's an Ai SkyDome.…Let's open its attributes with Control + A.…And we saw the attributes for the SkyDome…in a previous movie.…The only thing we want to do…in this case is increase the samples to five.…And that will get a higher quality rendering.…We can also make this sphere larger.…Scroll down to the Viewport section…and set the sky radius to 70,000.…
We won't see anything in the background here…but at least we don't have…this distracting sphere over there…Now let's go to the Ai physical sky parameters.…We can get to that either from…the Go To input node button in the Color attribute…
