Instant changes in settings

[Anonymous]

Hello guys i have an issue with a multable surface materials that has to do with setting the percentage in there settings.

For example i have a metal surface that is blue and when i render it in cinerender it is too shiny so when i change its shinning surface settings to a lower number lets say from 60 to 59 it just jumps from a really shiny surface into a really solid painted metal. I dont how how to fix this and i have this problem with glass surfaces as well.
