Edit UV mapping for a Vismat material in SketchUp

Hello :wave: SketchUper and vray renderer, i have a question about how to edit the uv mapping for a vismat material in SketchUp, like vray in 3dsmax we can make it in gizmo editor and put it box mapping and scale it as we want, for example i have a problem when i create a standard material in vray and i put a tiles bump in bump map editor, the problem is that i can’t edit the uv mapping for the tiles at the model…or if i put a noise effects in bump its the same i need to make it uv mapping as a box to scale it… Plz help :frowning:
