That's a huge improvement Marc, that is now looking like it is supposed to!

So if that issue is fixed in Octane now, the only thing you should need to do when exporting from MoI is to uncheck the "Weld vertices along edges" option at export time.


Could you also try the single polygon file from here:

What does that single polygon look like shaded in Octane now?
