Directing Skydome light visibility

- [Instructor] In Arnold version 5,…lights have visibility attributes…that determine how much that light will contribute…to the various render components…such as diffuse and specular and volume.…And for an Arnold skydome light,…we can also control the visibility to the camera…and through transmissive materials.…Let's do a rendering.…Go to the Arnold menu and choose render…to open up the Arnold render view.…Select the skydome in the viewport,…and open up its attributes, Control + A.…

At the top of the attribute editor…for the AI skydome shape node…are the skydome light attributes.…Scroll down a little bit below that…into the subsection for visibility.…And now we can control…each of the render components separately.…For example, if I want hotter reflections in the river,…I can increase the specular amount.…I'm not limited by this slider.…I can bring it down to 0…and I've got no specular reflections.…Bring it up to 1,…and I've got full specular reflections…as determined by the physical simulation.…

But I could just type in another value here,…
