Vray material translucency and scene scaling

Hi Everyone

 

Im working on a pipeline which involves a lot of moving scene back and forth between different plattforms, to finally be rendered with vray standalone. With all this moving comes rescaling the scene from millimiters to meters. This is done with the commands

 

- units.SystemType = #meters

- rescaleWorldUnits 0.001

 

Everything works fine, except for vray materials which has translucency on them. Their specular color changes drastically and no matte how much I tweak the thickness/fogbias/fog system unit scaling I cant bring the amount of translucency back.

In fact ; past a certain point of scaling there seem to that the thickness/fogbias sliders start loosing effect. I can for example put the thickness down to 1 mm , or 100000 mm and the effect is the same. Have any of you had this problem, and if so: How did you solve it? Am I looking at the wrong parameters?
