3DsMax 2017 to Keyshot wierd graphical glitches, please help.

[d149st]

Hey guys, I am suddenly having this bug were when I press Clear All the texture appears like it is glitched on Keyshot. I am using the 3DsMax to Keyshot export plugin.
If I use the smoothing groups it fixes the bug but.... as you can see on the second image the edges become too soft for me. I don't like this result. I never used it.

This started to happen after I installed the latest version of 3DsMax 2017. Before that I didn't have any problems.  (I don't remember if I had either the 2016 or 2017 very sorry). But anyway before I would always press Clear All to get the sharp look without smooth edges. I uninstalled and reinstalled keyshot but to no avail. Please help I need Keyshot for work.

Thanks!
