Decal Widget is missing

Hi,
Unfortunateley i am not able to find or use the Decal widget in my Rhino Version 6
with Vray 3.60

I found a hint that that its vrays fault - putting his own button in the property panel, but i cant figure it out how to fix it - and i cant find any documentation adressing this problem…

Help would be appreciated!
