Hey guys i have a quick question that im trying to figure out. I've been going through all the vray for maya videos and I was wondering, is there a way to apply 1 texture input gamma to all the textures in my scene?

So basically I'm trying to use only vray attributes on everything. i know i could use a gamma correction utility in maya but I'm rather looking for a way to apply a vray texture input gamma node to everything.
If anyone has a workflow going for that, id greatly appreciate the assistance.
