Quote - And I'm not sure how to add your wish to the wishlist as there is already an entry for subdivision

Yes, I know. Except that there is a difference between subdivision "because we want even better results" and subdivision "because we hope to get acceptable results".
To put it bluntly, the tests rg5a did (and posted in the Lux forum) were done with whatever subdivision LuxPose is capable of right now (23a), so it is clearly very far from being enough. It seems we need more, much more, and that's what the post was all about.
(Now, how much more, that's another question - only tests will be able to tell)

And to put you own (LaurieA) concerns at ease, rg5a has gone to great lengths to make sure it wasn't a LuxPose issue before posting there - if there is a couple of people who don't want to look like fools to the Lux crowd, we're part of it. We've got 2 other issues pending, but rg5a wants to wait till the weekend before posting them over there, to make sure they're reproducible and not just due to our own computers.
