Trouble with Smoothing Groups

Hi,
one of the best feature in lw 2019 is the smoothing groups and I'm using it a lot because I avoid to divide my object only to stop the smoothing.
I thought in Octane the smoothing groups work great because in IPR the render is perfect, as I see in native and in openGL.
The problem is the final render (F9, or F10, or screamernet). The smoothing groups don't exist.
There is a way to resolve this issue?
I attach a couple of images to show what happens in the final render, you can see a simple object with some sm.gr. assigned. IPR is ok, F9 is a disaster.

Thank you for the help.
Bye
Gianluca

Hi,

This sounds like some kind of bug or limitation on the LightWave side. Somehow the smoothing groups normals are not computed in the final F9/F10 rendering stage. I'll investigate it to be sure and report this issue to the LightWave dev. team if finally it is a LW limitation.

Thanks,

Hi,
I tested it with native engine: VPR and final F9 render both right, the problem is in Octane final F9. If the bug is in lightwave side and we wait the LW dev. team to resolve it, I afraid we lose the hope to see it fixed...

In any case thank you for the help.
Have a good day
Bye
