turn off reflections

hi at all

is it possible to turn off the reflection on one object but not on the other on?

thanks for the help

Your question is really too vague !

What renderer are you using ?
Do you want objects not to receive reflections or cast reflections or both ?

Please supply a simplified example blend file of your scene

oh sorry …

the reflection on the jar are to big and i want to remove it from the glass but not from the rest of the robot
