I just started working on doors. Oak & Iron have been designed so far.
As side note, a warning though. As doors consist of two blocks, it’s difficult to design a seamless design between the two parts, meaning it’s not possible to have strong normals nor overlapping heightmaps otherwise the seams become visible and the POM glitches out. I chose to use POM for the “windows” only and very soft normals to avoid visible seams as much as possible.
