vray sphere fade, objects outside still rendering

[stevesideas]

Hi there,

Im having to render a section of an animation using vray sphere fade. When rendering, a section that isnt within the radius of the sphere still renders out (including alpha). The object is a blend material that is transparent. Any ideas how to stop this ?

Cheers

I've had problems with this on my glass materials before. Thankfully it's never strong enough to cause an issue but i'd like to know what causes this too.
