Bump effect shows up on material preview but not on render.

I just updated V-Ray to the newest version today. When trying to render a interior scene, I noticed that my wood floor was completely flat. Every time I change the multiplier and the bump type, the material preview reflects those changes, but when I render the scene I continue to get a flat, bumpless floor. Please help!

Hi
I made some test with bump and I'm not able to reproduce your issue. Bump mapping is working fine for me. Is there any way that you can share your scene with me?

I was able to fix the problem by duplicating the problem material and using the new one.

This is weird. Do you still have the original material with the bump issue? If yes, can you send it to me? I'm curious why the material is not working.
