Hi Brian,

There are a bunch of duplicates in that listing, I think it's 4 different possible rotations with each rotational position being possibly diagonally mirrored or not, so 8 different possibilities.

That's actually why it is controlled by the pick location, so that you can control it directly with your pick rather than going into some dropdown and using trial and error going through 8 different possible choices.

I've been thinking about adding a mirror (basically exchange u and v directions) as another option so you could correct the case of when you have clicked right in the corner of each surface which then does not control the mirroring very well. When you pick you don't want to pick directly on the corner itself, more like on one edge somewhat near the end of the edge but not right directly at the end since when you're on the corner you're actually on 2 edges at the same time.

So like one of these 8 red spots here:
