Im having issues with the quality of a reflection, here are 3 screenshots

Here is the object with reflection turned on. How do I smooth this out?


Here is the mesh of the object.


Here is the object with reflection turned off.


I thought it was the displacement map that raises the surface of the object slightly but even with that turned off the reflection looks bad.

it looks like the displacement map yes (that's the usual result unless the map is higher res and even then it depends on how close you get to the surface with a camera) and the bottom looks normal too, with that flat a surface the light would have to be at just the right angle to reflect into the camera and it's probably not.

If you want a slightly domed surface for each tile and it needs to be smooth you might want to consider Subdivision surfaces

Here is a screenshot of the object without a displacement map. Something still looks wrong. It just seems that I need to adjust something in the render settings but i'm not sure what.

By default lights don't appear in reflections, but you'll see a fake reflection in the specular channel. If it's an area light and you've turned on the "show in reflections" option in the Details tab that could be causing the problem.

As Brian said, it's hard to say for sure without seeing the file.

it's the Blur Offset/Blur Scale in the Bump channel .psd - if you want to blur the bump a bit do it in the texture (it's big enough)

oh I see now. I also see that when i turn displacement map back on its messed up also. it looks like if i set that to .5% it looks better

thanks for the help.
