Hello guys good day.
Can anyone tell me why vray always messes up my textures ? … Im really lost now… 
pls post the .skp or a screenshot with View>Face Style>Monochrome, so we can see what you are up against
Lots of reversed faces, usually the front faces are white and the back faces are blueish gray, try to apply textures on the (front) faces only, not on groups or components
