Path Traced Fog and Camera Animation

I am new to Omniverse and really enjoy it.
I am having troubles finding Path Traced Fog, I doesn’t show up on render settings/under Path-Tracing and it isn’t there. Did this get changed or removed.

Also, animating camera? How. I go to the curve editor, set the keys and nothing happens. I am find little to no documentation on these?

Any help would be appreciated.
