$\begingroup$ I really thought I tried that and it didn't work! Apparently I did something wrong. This is the useful answer for me because it preserves neighbourhood relations. Triangulating faces separately doesn't. If you look carefully at the images in the other answers, the subdivision of the cube edges isn't identical between faces either. With this method it is. $\endgroup$

$\begingroup$ @Szabolcs Ah yes I see what you are saying. Just as an FYI, you could always add an extra step after triangulating faces separately and fix that issue with RepairMesh[r2, "TJunctionEdges"]. $\endgroup$

$\begingroup$ I didn't even consider this. Feeling a bit foolish now... $\endgroup$

$\begingroup$ @Szabolcs What version are you on? All 3 of those examples work for me on 11.0.0. $\endgroup$

$\begingroup$ @ChipHurst I am sorry, I am stupid. I used MaxCellMeasure -> number instead of MaxCellMeasure -> {2 -> number}. Need more coffee ... won't comment today anymore before thinking things through 3 times. Yes, everything works correctly. $\endgroup$
