how to decrease or increase vray light subdivisions globally

[chow choppe]

hi all

i was just wondering if there is any way or maybee any script where i can change vray light subdivions of different lights together when they are not instances.

basically i have lot of lights in a scene with varying intensity and are not instance of each other. so i want a way to make their subdivisions hig or low like 8 or 24 or vice versa in one go. so that i dont have to do it by selecting each light and changing subdivisons one by one.

in vray light lister it shows all the lights but i am not able to select them all there and just make subdivions same in one go.

 

any advice on this?

 

thanks
