Matte not blocking sun

[Bpositive]

Hi

Why is it that my matte objects are not blocking light coming from the sun?

I'm getting long sharp shadows from the sun, when there only should be diffuse shadows.

Can you attach that scene for investigation?
Let us also know the exact versions of V-Ray/3DSMax.
