how do i create .vismat files?
you can also do pack material in the new Vray 1.49.01. it will be saved as zip file. if you want to share it or save it into another computer with texture on the folder.
You want it available in SketchUp's material library?
After you have imported it, export the SketchUp material as an .skm. In VfSU 1.48.xx the V-Ray properties are saved with the SketchUp materials.
