MR Photons attributes

When I open the Photons Attributes section of a material (say Phong), I only have 2 settings: a "Derive from Maya" checkbox, and a "Take settings from Maya" button. I'm using MR public beta for OS X with Maya 4.5. I guess we should have here Photons attributes like shinyness, absorbs or translucence. Could anyone using the PC final version of MR tell me if there are more settings than just these two buttons?
Thanks,
Alex
