hidden edges in vray for 3ds max 2013 and 2015 not disappearing

the interior edges using a semi-transparent wireframe material won’t disappear. i’ve tried to toggle on and off the ‘hidden edges’ of vrayedgestex but no luck. i noticed that when rendering with vray adv the edges don’t show up, but the result is much better using vray RT. problem is i can’t get the interior edges to disappear. ideas?

here is the rendering using vray RT

Unfortunately the “hidden edges” option is not taken into account when render with RT. This is a limitation which we are working on.

but the result is much better using vray RT
Is there any render difference between the Advanced and RT/CPU renderer in your file when V-Ray EdgeTex is removed from the setup?

We have fixed this for the next service pack.
