I actually wasn't trying to make anything look shiny. What I wanted to do was make sure that textured objects and flat-coloured objects could sit next to each other and look like they had an identical finish - a plain, matte one.
I was fiddling with the "shininess" property at first because I was confused by something the engine did. Apparently a WhiteShadingBitmapMaterial contains a lot of sub-maps of varying light levels, and in the first few frames of rendering a Scene, it fills out those sub-maps - but until it does, the surface can look inaccurate; either too bright or too dark.
