VrayMaterial translucency + rescaleWorldUnits

Hi everybody, I'm working on a pipe back and forth between 3ds max / other 3d platforms, and on to Vray Standalone for rendering. In order for the conversion from 3ds max to work well, I need to change the units setup, and rescale he entire scene using the maxscript command rescaleWorldUnits. This command works exactly like "Rescale world units" utility. The Problem lies with what it does with translucent vraymaterials.

 

Say that I scale down the scene by a factor of 0.01. The translucency effect breaks, and even if I take the original thickness multiplied by 0.01, it doesnt change anything. the material does not seem to react at all no matter what number I input.

 

Now, if I skip the rescaling and just change the units, it all works perfectly. Is there some hidden (or embarrassingly obvious) parameter I need to change in order for this to work?
