Hi Jamie, thanks for testing that.

So yeah, there is absolutely no indication of the actual vertex normals being used there for the shading whatsoever.

It's pretty obvious that only the face normal is being used to shade it.

That would probably be a good example to send over, since it is so simple with just 1 polygon in it.


Did you use any particular import options into Octane for that render? There is something like a "Use smooth groups" option, was that option enabled or disabled?
