WCS material scale mapping in VRay Rhino

Trying to scale a material in the VRay material editor (World Co-ordinate System) so that a brick material will always show bricks at the correct size. Any idea where the WCS options are in the VRay material editor? Thanks!

Use the texture mapping controls in Rhino instead.

But I want to use VRay materials. The rhino material editor is turned off when I use VRay rendering.

The texture mapping is a property of Rhino OBJECTS, not the material–well, on top of it anyway. He’s saying to go to the Texture Mapping page in the Rhino Object Properties panel.
