Ray Epsilon problem

[jeremyshin]

Hello guys,

I have a problem apparently with Ray Epsilon.
Basically I have a simple low poly mesh with a simple image in the diffuse channel, glossy material.
Problem is that I have some kind of light leak at the mesh intersections. I redeuced Ray Epsilon to the minimum, which helped but the problem is still there.
I have tried to tweak every settings, without success.
If I use Directlighting Kernel, the problem is gone... but I want to use Pathtracing, there is absolutely no reason to have this issue.

You can see the issue in the attached picture, it is with Ray Epsilon to the minimum.

Thanks, J.

Setting GI Clamp to 0.03 helped reducing the problem.
I work with 2020.2-R3, latest drivers.

I am not sure that it is normal to have to set GI Clamp to 0.03...

I can send a scene in PM if needed...

What are the dimensions of the object?
You can use the InfoChannel passes to check the geometry.
