Bump Map Not Rendering, Bleaching Material Instead

[zacharytyler]

I've been pulling my hair out fudging with settings and I can't get close to figuring this one out.

I'm trying to apply a bump map to some wood-siding that I'm doing for a client in Vray 1.01 for Rhino 4.

With no maps, the material rendered looks like this:

 

For hyperbole's sake, just to see if I can get an effect, I've added this bump map:

 

And the rendering, with bump map, turns into this (Intensity 1):

 

 

The Material is just a basic 20%grey with no special settings. This seems to be happening to all materials I've toyed with.

I've tried multiple bumps, tinkered with settings, and used different Indirect Illuminations.

 

I have a rectangular light facing the surface, the only Environment Light is the GI, set at White and 1.

 

The bump map settings I've toyed with a lot but they're at default now.

 

Anything you guys could suggest would be amazing, since I've pretty much hit a brick wall here. I've tried to include relevant information but if there's anything I'm leaving out let me know

 

Thanks
