I'm trying to get started with the Avatars SDK on Oculus Go using Unity 2018.2.15. I have the latest version of the Oculus Integration plug-in (1.34).

But when I run any of the samples, the avatars appear as translucent white columns, sometimes accompanied by pink blobs that may be hands. Here's an example from the Avatar Gallery sample:
Any idea what's gone wrong here? How do I get avatars to appear actual avatars?
