VRay Glossy tutorial

[mauarduz]

If comeone could guide me with what kind of maps are places in the glossiness slot in reflections parameters depending on the material we want to obtain, say, plastic, metal, etc etc.

 

up to now i just used the glossi % lets say, below 1.0, .85; .95, etc, but rendering times get 2 high and i have an average machine to work with.

 

so maybe with a map on the glossi slot i can lower rendering times ?

 

thank you for your attention.
