i have some questions about materials now. what material should i use in poser to get glossy in lux.

how to change the IOR settings in poser?

do we have to use blinn or just the specular node?

can we use textures for reflections?

The standard material is glossy if specular is set, else it is matte.
As far as I can tell BB makes use of the blinn node. 
I don't use plain materials BB's converter exports. So I can't tell much about it.
For skin I replace all materials to mattetranslucent or velvet.
