Trace sets problem for multiple objects

Hi,

when I select object I can go to VRay object properties - Trace sets and change settings for reflections and refractions.

But when I have multiple objects selected, both settings are grey out. When I need the same settings for more objects I would really like to change settings for all objects once.

Is there any way or is it a bug?
Can you please make this possible?

Thank you.

I wrote a script for this once. Check this thread and try the last version (post Private Messages ).

oh, never saw that. Thank you, I will test it.
