Oculus equivalent to "SteamVR_loadlevel" in Unity3D?

Hi all. Newbie here. I'm not much of a C# coder, so I use prefab scripts for most of my work. I want to switch my app to Oculus SDK, but can't find a ready made C# equivalent to SteamVR_Loadlevel. I'm not sure how to smoothly move from one level to another without something like this. The standard Unity load_level didn't work well in VR when I used it. I'd be grateful for a link to a script I can use. Thanks in advance for any advice!
