vray and displacement on a bottle surface

[syokaku]

hi everyone,
I modeled a bottle, now the client asked to me to put a logo beveled on the glass surface of the bottle. I thought to use the vrayDisplacementMod but I don't know how to use the map in the right way: I need only one logo on the entire bottle surface and I need it in a certain position on the bottle surface –*I need something similar to a uvw unwrap applied to the vrayDisplacementMod.
Is there any possibility of doing this?

thanks in advance.

yes,just unwrap as usual,place your logo.Then use that image in the 3d slot of the displacement modifier.If you dont unwrap it will try to stretch the logo over the entire circumference of the bottle.
