Vray material not cooperating

[jtroupe]

I am using a spanish tile material for the roof and it is acting funny on the edges. It is casting a shadow, and then the displacement is giving me 2 different sizes of 'humps' even though it is the same material and the same layer.

Any help woould be appreciated.

for the different sizes of the tiles, you have two different uvw's on the roof object.

 

check that your displacement is set to '3d and then check the 'keep continuity.

I only have one uvw map mofidier on that layer, and there isn't a displacment modifier on it, that is the material.
