f-edge not working OK.?

[Harutium]

My f-edge plug-in over max 6 is not working as
expected: Despite I add a f-edge map in the Bump slot, with 100%
intensity when rendering the ghost of original square edges still appear behind the new rounded ones.
Am I doing anything wrong or what?
thanks

I think that would be expected since the GI is going to look at the base geometry

Could you post a picture? We just used f-edge on a project here with VRay and GI, and we didn't see anything like this.
