Renderman and Subdivision!

Just got reminded today that polygonal geometry in Renderman needs to be subdivided to appear smoothed during rendering.  There was this problem about certain faces of an object in rendered appearing much brighter than their neighbouring faces. Those bright faces stood out like sore thumbs in the render.  For Mengdi and myself, this was our first time doing look-development with Renderman. We did a lot of tests, trying lots of ways to solve it.  Being quite new at Renderman and look-development, we tried lots of stuff: - turned on/off the lights one by one - tweaked shaders - removed shaders - disabled reflection lights - switched between point-based occlusion and real-time rendered occlusion - switched between baked and on-the-fly reflection occlusion  - and all of that.  None of it worked. During the trial and error stage, it occurred to us that the geometry may not be smoothed. I had meant do tests to find out if the geometry was smoothed/subdivided in our Maya viewport, if it
