Ray epsilon by default : 0.0001
and my scene is 1:1 scale (3 meters height)
I tried to change my ray epsilon but same shit

It's hard to tell if you're really a getting light leak as it appears, or if it's just a quirk of your geometry shape and lighting setup. If your scene is what I am imagining, that might actually be correct. It looks like a simple scene; can you upload it, or a stripped down version with just the visible geometry and lights in your example?

Could it be a phong shading issue perhaps? Try messing with that a bit :)

Hi,
you can use the Info Channel Kernel to check the geometry, try with Geometry, Smooth, and Shading Normal passes.

Try zipping your scene and the using the "Upload Attachment" button on the bottom of window, then "Choose File", then "Add the File".
