The charting of this plane is skewed

Unity Engine

I’m doing realtime GI for a room. Essentially there are four walls, a ceiling, and floor.
After the Realtime GI calculations are complete, the ceiling is rotated in the atlas. Whereas everything else is nicely aligned. Why would this occur for this mesh? It is completely a flat plane and aligned with the word axis’.

Thanks, I’ll look at that document.

Edit: Clicking “Preserve UVs” then causes the island to be aligned nicely.
