Rendering images with the Render Studio package using Creo 10

When rendering images with the Render Studio package that comes with Creo 10. Bump maps, which I use all of the time to represent things like fiber wrapping on tanks, iso grid structure, weld beads, etc., are not being scaled per my inputs.  This is especially useful for representing threads. I have a basic raster image for threads that I apply to a threaded surface, and just scale it along the revolve axis as needed to represent the number of threads that should be there as a function of the cylinder length, and the thread pitch.  Thread bump maps are being rendered, but with a default scale of 1 along the rotational axis. These results are whether I use a parametric or cylindrical mapping for those textures. I don’t know if there is a setting I missed, a configuration value I overlooked, or what.
