Just wanted to note that VRayMtl’s - Basic parameters - Rougness does not render correct in the Render Element VRayRawLighting as long as there is no VRayLighing-Element and VRayDiffuseFilter present.
Also note the brightness of the Translucency of the VRay2SidedMtl, which is messy without VRayLighting, too.
Sorry if that is known and or fixed already 
See attached Max-file

Thank you for reporting this.
The Roughness issue is already fixed in V-Ray NEXT BETA.
For the Translucency issue we will take a look and I hope we will have a fix for that soon.
