if you have same problem, it can be help you

There is a miss point in the lab renderer shadercode. in vr_standard shader code vNormalWs is activate when !S_UNLIT. but in vr_standard code line 355, you can see a error

#if ( S_RENDER_BACKFACES )
{
i.vNormalWs.xyz *= ( bIsFrontFace ? 1.0 : -1.0 );
}
#endif

if you use option unlit and render backfaces, error will be occur.

change code like this :

#if ( S_RENDER_BACKFACES && !S_UNLIT )
{
i.vNormalWs.xyz *= ( bIsFrontFace ? 1.0 : -1.0 );
}
#endif

when occur "invalid vlavla~ 'vNormalWs'"
