Hi everybody, i have a question…  
Im using crazybump for vray sketchup, crazybump gives many maps as normals, disp, occlusion, specularity and diffuse, my question is, where do I have to use those maps in vray? I mean is normal map used for bump? Where do I use the specularity map?

Thanks for the help
