shadow/light problem

[new.ages]

hy guys!

i have this problem with shadows/lights with that wall material
you can see in the pics that there is light comming in a very shallow angle from behind the front side of the wall. so the wall should be in shadow. but in the rendering it seems that there islight curving around the corner.
its no smoothing issue and the problem is gone when i disable the bump-map.
its a simple white vray mat with a mix map in the bump.
light is vray sun/sky

any ideas?

You using VRayEdgeTex? Also try setting sun shadow bias to 0.0.

+1 about decreasing the shadow bias.

You could also try to move the sun slightly to one side. It seems that it's exactly parallel to the wall and I think it's not a very good lighting setup.
