What you are seeing is called "Moire" patterning, and is typical when rendering
something with very small repeatable patterns (e.g., brick).
Perhaps the instructions here can help:

Unfortuantely, the simplicity of Revit rendering means that often times you do
not have the fine control over parameters which will eliminate this issue.
