VRWorks 4.17 missing shader?

Hello, I found a problem - with a clean download from git branch VRWorks in 4.17 - I try to run a simple UE4 VR template project. When I try to run it in editor in VR mode then it simply crashing. Looks like there is missing shader (error on screenshot).

Assertion failed: ShaderRef != NULL && *ShaderRef != nullptr
Failed to find shader type TOneColorFastGS<false> in Platform PCD3D_SM5

Did anyone encounter something like that? Or is there some additional step to make when running VRWorks?
