VrayFur and VrayClipper interesting result

I’m doing a section for a window, using the Vray fur for the junction between moving parts, for the little hair that prevents air infiltration.

It is a mesh object in this situation, but the result will be the same if you are using the vray ‘plane’ clipper, I tried both methods
Where the clipper meets the fur, it creates ‘white’ blob, as you can see on the image.

This happens on Vray 3.40.03 for 3dsMax 2017.

Hello,

Does it change if you increase the max transparency levels ?

Best regards,
Yavor
