Hi Luca,

   That is a bug -- the shininess of helix axis cylinders should change using the shininess control.  I have fixed it in the Chimera daily build.  Tonight's Chimera daily build will have the fix.  Not sure if Chimera builds will work tonight due to a power outage yesterday at UCSF.  Look for Chimera build dated Nov 14 or later.

When I try to reduce the shininess of the figure, I can change it for the ribbons (Viewing -> Lightning -> Shininess) but not for the axes, that remain unchanged (very shiny). Is there a way to change the shininess for all objects, ribbons and axes?
