Object - Ground intersection area problem

Hello,
I tried many things to prevent this problem but I couldn't. There is a shiny slice at intersection areas. What is the problem here?

Read ray_epsilon parameter in the manual to learn it.

This ^
It is upmost important to acknowledge that a change of the Ray Epsilon is often caused by
a wrong-scene scale. Therefore, implying that the scene-scale
has to be properly adjusted (to avoid many rendering issues), which wouldn't require to change the Ray Epsilon (aside from edge-cases that call for it).

hi,
Sure, I will read docs.
But before posting this problem I tried that but it didn't work. I tried so small value like 0.000001.
There is a ground (plane object) in the scene and single HDRI Env. I've added another plane object under the ground object (I mean it is not visible actually) and problem is gone.
@elska for the scale issue, I tried some test with a new document. With default RayEp value there was the same problem. I will try to change project scale values to see its effects about this problem.
thank you

Your objects are tiny. Just making the ray_epsilon too small that's fixing the issue.

Okay,
thank you.
