Bump disappears with spotlight on (VRAY for SU)

[dr.raoul]

Hi, maybe it is just a silly button
to press in VRAY for SU, but I can't find a way to keep the bump
on a wall when it is lit with a spotlight.
My rendering always keeps shows up very flat.

Anybody can help?
Best and thanx in advance
Raoul

Hello,

PC performances, SU and VRay versions, VRay options and materials settings ?

It very much depends on the direction your light is shining from. The more perpendicular your light source is to your surface, the more washed out your bump map will be. If you have your light closer to parallel, you'll get a more raking light and show up your surface texture much better. Can you post an image perhaps?
