Weird black spots with bump noise map

[AltoR]

Hello,

I am facing a strange problem: the scene is composed of:
_ a VRaySun + VRaySky
_ 2 test objects: a sphere and a cube
_ the material applied to the objects is a simple grey diffuse VRayMtl + :
a noise map on the bump slot (amount = 40)
Reflection is set to pure white
Fresnel Reflections is On, IOR set to 1.8
Reflection Glossiness is set to 0.7

When I do a render black spots appear on the objects as if the noise map was on the diffuse slot.
If I set the Reflection amount to 0 (eg pure black) the problem is gone.
I first thought it was caused by the Reflection's Exit Color so I did a test setting it to red. But the spots remain black ...

Please see the attached file to help me,

Thank you in advance,

and if you check fix dark edges in the options section of the material?

You fixed my problem !! Thank you so much !!
I never saw this option before ... How does it come it is NOT enbaled by default ?! And the VRay Manual is a bit confusing about it: "enabling this option will fix dark edges that some times appear on objects with glossy materials" ... What must I understand by "some times" ... This is odd ... Maybe Vlado could answer me ?
Btw: you ShowReel really rocks !

look under BRDF, fix dark glossy edges (im not sure if 2.4 has it though)

Ah ok. I think its on by default in vray 3.0

Ah ok. I think its on by default in vray 3.0

Yes it is - but only for the new created materials.

Thank you guys for your feedbacks, much appreciated. Hope I will soon get enough money to afford VRay 3
