White specks all over render

#1

Hi,
I can’t seem to solve this issure.
I’m using 3dsmax and vray 5 with the defult settings, brute force - light cache.
Most of the time these settings are fine but with this particuler scene I am getting white spots all over the image.
My model uses a hdri light scource for the daylight and vray lights for the down lighters, If I turn the vray lights off the specks dissapear so I know its somethig to do with the lights but what ? Please see image.
This image only took 6 mins to render but I did one over night which took four hours and it was just as bad if not worse.
Any help with this issus will be greatly appriciated.
Matt.
