If I havea  Poser texture, that is (for example) a checkerboard pattern...in poser I can change the U_scale and V_scale to affect the size of the checkerboard pattern on the clothes I apply it to.  (the u_scale and v_scale on the image map node)

I don't seem to be getting this coming over into Reality?

Is it somewhere I am missing?  I only see "scale" referenced once in the docs, and its not in regards to this.
