I have a prop which uses a few shaders from this pack, especially the wireframe one: https://github.com/netri/Neitri-Unity-Shaders

Currently these are broken on the beta - same avatar works fine on the live version. It's really hard to describe the effect, you'd probably have to go see it - the debug robot available in the Avatar Testing Chamber has a feature which uses this shader.

Seems to be only in VR though - it works in desktop.
