Quote - ok i see that if you connect the textures to the specualar that it works.

now i only need to find out how to change IOR for reflections.

Reflections? This is how glossy is defined:

glossy::d float texture The depth (thickness) of the coating layer for absorption effects. (0 = disables) 0.0
glossy::index float texture IOR of the coating. 0.0
